INTRODUCTION • • The major objective of this report is to supply the City of Fayetteville with a feasibility study for an intercity bikeway system This is the ground work from which future activity can be generated. These activities include the generation of public awareness and involvement, the development of an informed bikeway committee, detailed planning, and future cost analysis. It should be noted that a project of this complexity will take years of continued planning and funding to complete It must be included in the general plan for the city as a component of the transportation and recreational systems requiring continuous monitoring, evaluation and feedback. As is discussed throughout the report, there are several elements and different standards which can be incorporated into a bikeway system. These differences in standards affect the quality of the ride experienced by the bicychsts as well as the safety of motorists, pedestrians, and bicyclists. As is expected, the better the quality of bikeway developed, the higher the costs. As the project unfolds, the quality of the bikeway will be dictated by the public's interest and involvement, as well as the cooperation of Fayetteville's Public Works Departments for implementation and future funding. It must be stressed that for any bikeway system to be successful it must be planned with pubhc input and developed to the highest possible quality. A portion of the funds that have been authonzed by the Intermodal Surface Transportation Efficiency Act (ISTEA) are to be allocated for further planning stages in which the pubhc, as well as representatives from the city development departments are to be mvolved m the design, implementation and maintenance of the project. 1 II. NEEDS ANALYSIS There is, without a doubt. the need and public desire for an intercity bikeway system in Fayettville. Research on the concept began in 1978 with a survey of bicycle use among the residents of the city. In 1980, a Bicycle Task Force was formed to discuss the possibilities of a major bicycle transportation way throughout the city. Since then several interest groups have formed to show support for a future bikeway. The latest being the Bike Route Advisory Committee which was formed from the Northwest Arkansas Bicycle Club Many issues have been discussed and are reported to be of highest concern. Among these issues are: * Safe transportation for both the commuting and recreational bicyclists; * A route that will connect to an utter -county bikeway system; * Special attention for the safe commute of grade school children; * Educational programs for safe bicycle riding; * Greenways connecting public green spaces. Due to the increased public awareness, funding for the project was included in the capital improvements plan and a grant application has been made through the Arkansas Highway and Transportation Department for Enhancement funds under ISTEA (internodal Surface Transportation Efficiency Act). 2 • • III. BENEFITS • • Bicycling benefits both society and the individual. Communities that have successfully implemented bikeways have found that by integrating exercise, transportation and recreation on a daily basis, participants have enhanced their lifestyles. Not only can a bikeway improve the life of the bicyclist, but everyone in the community. An increased use of bicycles will effectively reduce traffic congestion and parking needs. This along with the obvious reduction in harmful auto emissions and noise pollution are all considered incentives for other communities to support long term investments m bicycle facilities. The benefits of bicycling as a method of transportation are obvious, as are the benefits of an established bikeway system for use by bicyclists. Benefits include providing the most direct route for utilitarian use, helping create a pleasurable experience for the recreational cyclist and incorporating more challenging routes for competitive rider while maintaining safe access for all. 3 at IV. PLANNING A BIKEWAY SYSTEM is composed of bicycle paths, lanes, and routes all interconnected and spaced closely enough to satisfy the vanous needs of the bicyclist. Three pnnciple questions must he addressed and resolved if a bikeway system is to be successfully achieved in the City of Fayettville. These questions are: "Where should the bicycle facilities be placed?", "What type of facility should be provided?", and How much money should be spent on a bicycle facility development?" The answers to these questions are not easily determined because they involve value judgements as well as complex technical considerations. For this reason it is apparent that further research must be gathered and analyzed by an informed group of public citizens, recreation professionals. and representatives from municipal departments before a finalized report can be prepared. However, this feasibility study will serve as a guide to developing a bikeway system. A system that will provide bicyclist of Fayettville with a safe and efficient means of transportation while alleviating conflicts experienced by motorists. 4 • • • • A. WHERE SHOULD BICYCLE FACILITIES BE PLACED? The answer to "where" mvestments in bicycle facilities should be directed, must rest on an investigation into the potential types of uses of the bicycle. Smce it is clear that the bicycle is bemg utilized for a wide variety of recreational and purposeful trips, it follows that investment in facilities should reflect these diverse interests. In general, bicycle trip purposes can be divided into two broad types, utilitarian and recreational. For a bicyclist on a utilitarian trip, the primary objective is reaching a specific destination quickly with few intemiphons The bicycle is simply the chosen mode of transportation. On the other hand, a bicyclist on a recreational trip is ndmg for pleasure; the destination is of less importance. Of course, for the vast majority of trips, these purposes are not absolute or mutually exclusive. That is, most trips will have some utilitanan and some recreational purposes. New bicycle facilities, therefore, should be designed to accommodate the needs of the anticipated mix of bicyclists. Bicyclists differ widely in their abilities and in their preferences for riding environments Some bicyclists place high importance on directness and have the ability to nde safely and confidently m heavy traffic. Other bicyclists place more importance on the quality of the trip and are willing to go out of their way to ride on residential streets and paths. Thus, bicycle facilities should be planned and designed to accommodate a broad range of cyclists, fulfilling the needs of a large percentage of the public. 5 The following categones of bicycle transportation systems are proven to have the greatest potential for bicycle use. Many cities that have developed successful bikeways have used these guidelines to locate where facilities should be placed. Table A will provide specific examples of these systems. PENETRATOR SYSTEMS - If the bicycle is to be utilized as a purposeful trip - making vehicle, it will be necessary to provide facilites leading into concentrations of high employment or other high use areas such as shopping centers and universities. Unfortunately, intense motor vehicle traffic in and around these high activity areas will often preclude safe hicyclmg. Bicycle facilities penetrating into these areas are bound to be costly or unfeasible in many situations Nevertheless, where opportunities do occur, expenditures higher than usual might be justified when high use is anticipated. INTERNAL SYSTEMS - There are few areas within the metropolitan area where a well designed bikeway system could result in the bicycle being the primary means of transportation. This is particularly true on college campuses and in regional parks. Many major institutions such as the University of Arkansas have shortages in convenient parking; accommodation of such parking would be costly. A well designed bikeway system would provide a efficient, low-cost transportation alternative with low storage area requirements. Potentials for internal bicycle system exist within the University of Arkansas. ENVIRONMENTAL LINEAR CORRIDORS - Unfortunately the most expensive and complex bicycle facility to develop is that of the environmental bikeway corridor totally separated from motorized transportation. These facilities often preserve and enhance large portions of a city's natural resources while providing both leisure and utilitarian bicycling for the community. Since the Fayettville area experiences such hilly topography, the potential bikeway development along natural stream hanks should receive specific attention These floodways provide a very desirable flat gradient that encourage bike use. 6 • • NEW LAND DEVELOPMENTS - The most effective bicycle transportation systems are developed concurrently with the vehicular system. Particularly close attention to future development of the bikeway system should be undertaken in the future development areas. Development incentives could be built into local ordinances to encourage private developers to provide facilities for bicyclists as part of their residential, commercial and mdustrial developments. TRANSPORTATION LINEAR CORRIDORS - There is an opportunity to provide the most direct routes for bicycle facilities along major transportation corridors such as highways, and major arterial roads. To develop these routes most efficiently, the bicycle facilities should be incorporated during construction or reconstruction. RECREATIONAL LOOPS - Located within the Ozark Mountain range, there are abundant opportunities for bicyclist to enjoy scenic routes along rural roads surrounding the City of Fayettville Many recreational routes have been established and must be accessible from wrthm the city hmrts. To develop a comprehensive bikeway system, facilities accommodating these rural routes must be incorporated. 7 • • HIGH POTENTIAL LOCATIONS FOR BICYCLE FACILITIES Penetrator Central Business Districts Systems Large Employment Centers Shopping Centers Schools and Universities Parks Internal Systems Colleges and Umversiues Regional Parks Environmental Stream Valleys Linear Ridge Lines Corridors New Land Developments Residential Subdivisions Large scale P.U.D.s Transportation & Highway Right of Way Utility Corridors Utility Right of Way Recreational Loops Enure urbanized area Rural roads Table A 8 • • B. WHAT TYPE OF FACILITY SHOULD BE PROVIDED? A BICYCLE FACILITY denotes improvements and provisions made by public agencies to accommodate or encourage bicycling, including parking facilities, bikeways maps, and shared roadways not specifically designated for bicycle use. There is a wide range of facility improvements which can be incorporated into a bikeway system. Improvements can be as simple and inexpensive as placing signs along an existing street to indicate a bike route or as complex and costly as providing a bike path, separate from any existing features. The controlling elements of the design of every bicycle facihty should be its location and the factors that are present Once the location that will best satisfy the most bicyclists has been identified, the following facilities can be chosen based on suitability. 9 • BICYCLE FACILITIES • BICYCLE LANE BICYCLE PATH Adjacent to Roadway BICYCLE PATH Separate from Roadway 1W PIK* RM MTC Ya. 11 li 4 4 • BICYCLE ROUTES • Shared right-of-way located on lightly traveled streets and roadways designated solely by the standard "Bike Route" sign encouraging bicycle use and warning motonsts to anticipate cychsts on the street. A route is estabhshed to provide the bicyclist with a direct and desirable route to a specific destination WIDTH - Bike routes should be developed on roadways with a width of 28 feet or more, however, in residential streets where vehicular speeds are low and traffic is unobtrusive, a street width of 25 feet is acceptable. In general, 14 feet of usable width for each lane is desired. Usable width would normally be from curb face to lane stripe, or from edge Ime to lane stripe, but adjustments must be made for drainage grates,parking, and longitudinal ridges between pavement and gutter sections. USE - The cost of improvmg an existing street to include a bike route is minimal; this type of facility may be feasible as a connection between residential areas and designated bikeways. In areas where a direct route is sought along existing roads where factors such as street width and necessary on street parking make other facilities unreasonable, a bike route may be chosen for a short distance in order to provide continuous bicycle travel. As phases of the bikeway system are completed, Bike Routes may provide a temporary connection along roads that are scheduled for future improvements. Until the next phase is completed this will provide bicyclists with a continuous designated route to their destination. However, this type of facility is the least desirable and should only be used m low traffic situations or as a temporary facility. 12 BICYCLE LANES Spring Street Bike Lane along one way street •n..r 7 a4.- ,.rv'ti.z. W`-r^may 1'�.. Si . �..� ' +fir I Highway 265 Bike Lane 13 BIKE LANES The bicycle lane is distinguishable from bicycle routes in that it is intended for the preferential or exclusive use of bicyclists. It is developed along the outside lane adjacent to the curb. The bicycle lane is delineated by means of pavement markings or curbs. Pavement markings are passive in nature and may be easily crossed by motor vehicles. They include striping, full width pavement colorings, or painting, pavement markers and reflectable raised pavement marking. They provide the cyclist with psychological rather then physical protection. The use of curbs or bumper blocks provide a more protected separation however are not recommended as these have been found to be hazardous to the bicyclist as well as a maintenance problem. Bicycle lanes should always be one way facilities and carry traffic in the same direction as the adjacent motor vehicle traffic. Two-way bicycle lanes on one side of the roadway are unacceptable because they promote riding against the flow of motor vehicle traffic. Wrong -way riding is a major cause of bicycle accidents and violates traffic laws. Bicycle lanes on one way streets should be on the right side of the street, except in areas where a bicycle lane on the left will decrease the number of conflicts, such as bus traffic, excessive driveways or loading areas. WIDTH - Under ideal conditions, the minimal bicycle lane width is 4 feet. However, certain edge conditions dictate additional desirable bicycle lane width. To examine the width requirements for bike lanes, Figure 2 shows three usual locations for such facilities m relation to the roadway. Figure 2(a) depicts bicycle lanes on an urban curbed street where an on -street parking lane is provided The recommended bicycle lane width is 5 feet allowing the cyclist room to maneuver around opened car doors. Bicycle lanes should always be placed between the parking lane and the motor vehicle lane. 14 • • Bicycle lanes between the curb and the parking lane can create obstacles for the cyclist from opening car doors and poor viability at intersections. This placement also prohibits the cyclist from making left turns and therefore should not be considered. Where parking is permitted but not indicated by a marked lane, as exists throughout most of the residential areas within the City of Fayettville, a combination lane for both motor vehicle parking and bicycle use should be a minimum of 12 feet. Since many of the streets in Fayettville are designed with a width of 30 feet or less in residential areas, all on street parking would have to be terminated. Figure 2(b) depicts bicycle lanes along the outer portions of an urban curbed street where parking is prohibited. Bicycle lanes in this location should have a minimum width of 5 feet from the curb face. This extra width is suggested since bicyclists generally do not nde near a curb because of possible debris, of hitting a pedal on the curb, of an uneven longitudinal joint, or of a steeper cross slope. By providing a five foot lane, the usual 4 foot lane exists between the motorists lane and any pavement obstructions. Figure 2(c) depicts bicycle lanes on a roadway without curb or gutter. Bicycle lanes should he located between the motor vehicle lanes and the roadway shoulders. Bicycle lanes may have a minimum width of 4 feet, where the shoulder can provide additional maneuvenng width. A width of 5 feet or greater is preferable; additional widths are desirable where substantial truck traffic is present, or where vehicular speeds exceed 35 mph. This may suggest that existing shoulders be improved to accommodate a bicycle lane. 15 • • (a) CURBED STREET WITH PARKING 8'-10' 5' r Parking Bike Lane XXXl Motor Vehicle Lanes Bike Lane (b) CURBED STREET WITHOUT PARKING 8'-10' r Parking 4' 15n.)

Figure 2 16 INTERSECTIONS WITH BICYCLE LANES - Bicycle lanes tend to complicate both bicycle and motor vehicle turning movements at intersections. Because they encourage bicyclists to keep right and the motorists to keep left, both operators are somewhat discouraged from merging in advance of turns. Thus, some bicyclists will begin left icons from the right bicycle lane and some motorists will begin right turns from the left of the bicycle lane. Both maneuvers are contrary to established Traffic Laws and result in conflicts. At intersections, bicyclists proceeding straight through and motorists turning right ' must cross paths. Striping and signing configurations which encourage these crossings in advance of the intersection, in a merging fashion, are preferable to those that force the crossing in the immediate vicinity of the intersection. To a lesser extent, the same is true for left turning bicyclists; however, in the maneuver, the bicyclist has the option of making either a vehicular style" left turn (where the bicyclists merges left to the same lane used by for the motor vehicle left turns) or a "pedestrian style" left turn (where the bicycle proceeds straight through the intersections, turn left at the far side, then proceeds across the intersection again on the cross street.

EU J .I ra •lV e lli G I r I I H I I I I r I I L I Il BICYCLE PATHS Bicycle paths are the safest yet most costly facility designated exclusively for bicyclists and physically separated from motor vehicle traffic, where cross flow by motorists and pedestrians are limited. Bicycle paths serve a variety of purposes. They may provide commuting bicyclists with a shortcut through a residential neighborhood (eg. a connection between two cul-de-sac streets), create a scenic ride for both utilitarian and recreational trips, or supply access between park land along floodplain and utility easements. Bicycle path provide passage to areas that are otherwise inaccessible along designated roadways. Sometimes these facilities are located along major streets that are not utilized for other bikeway facilities due to existing site conditions. In general, combining bicycle and pedestrian right-of-ways is not desirable. Walkers, joggers, skateboarders, and roller skaters can, and often do, change their speed and direction almost instantaneously leaving bicyclists insufficient time to react to avoid collision. Similarly, pedestrians often have difficulty predicting the direction an oncoming bicyclist will take. However, in order to efficiently utilize funding, there are situations where the development of bike paths can be coordinated with pedestrian facilities in areas where both are lacking. Special design considerations must be addressed in these situations. It will be necessary to incorporate extra width as well as provide passive separation with the use of pavement markings and signage. WIDTH - The paved width and the operating width required for a bicycle path are primary design considerations. Figure 4 depicts a bicycle path on a separated right of way. Under most conditions, a recommended all paved width for a two directional bicycle path is 10 feet. In some instances, however a minimum of 8 feet can 20 Li be adequate. This minimum should he used only where the following conditions prevail: (1) bicycle traffic is expected to be low, even on peak days or peak hours, (2) pedestrian use of the facility is not expected to be more then usual, (3) the path is designed to provide safe and frequent passing opportunities, (4) the path will not be subject to maintenance vehicle loading conditions that would cause pavement edge damage. Under certain conditions it may be necessary or desirable to increase the width of the path to 12 feet; for example, because of substantial bicycle volume, probable shared use with joggers and other pedestrians, use by large maintenance vehicles, steep grades, and where bicyclists are likely to ride two abreast.

When this is not possible and the distance between the edge of the roadway and the bicycle path is less than 5 feet a suitable physical divider may be considered. Such dividers serve both to prevent bicyclists from making unwanted movements between the path and the adjacent roadway and to reinforce the concept that the path is an independent facility. Where used, the divider should be a minimum of 4.5 feet to prevent bicyclist from toppling over it, and it should be designed so that it does not become an obstruction in itself. INTERSECTIONS : It is preferable that the crossings of a bicycle path and roadway be at a location away from the influence of intersections with other roadways. Controlling vehicle movements at such intersections is more easily and safely accomplished through the application of standard traffic control devices and traffic laws. However, this would require extra stops along roadways which would be opposed by many motorists. Where physical constraints prohibit such independent intersections, or on roadways where extra stops would be a major inconvenience, the crossings may be at or adjacent to the pedestrian crossing. Right of way should be assigned and sight distance should be provided so as to minimize the potential for conflict resulting from unconventional turning movements. At crossings of high volume, multi -lane arterial roadways where signals are not warranted, consideration should be given to providing a median refuge area for bicyclists. Specifics on the design of Bike Paths are included in the Specifications section of this report. 22 I I BICYCLE PARKING Bicycle parking facilities is an essential element in an overall effort to ' promote bicycling. People are discouraged from hicycling unless adequate parking is available. Bicycle parking facilities should he provided at both the origin and destination of major routes and should offer protection from theft and damage. The wide variety of bicycle parking devices fall into two categories of user needs: Commuter or long-term parking, and convenience or short-term parking. The minimum needs for each differ in their placement. * Long-term parking - is needed at locations such as employment centers, bus stops, and multi -family dwellings.. * Short-term parking - is needed at locations such as shopping centers, libraries, recreation areas, and post offices. ' If bicycle parking is not properly designed and located, bicyclists will use trees, railings, and other objects. This practice can damage the object and create an obstruction for pedestrians. Several factors should be considered when planning and providing bicycle parking facilities. Location * the facility should be convenient and near building entrances, or other highly visible areas which are self policing. * ensure that bicycles are not where they will be damaged by motor vehicles * Facility should not interfere with normal pedestrian flow. Design * The facility should accommodate a wide range of bicycle shapes and sizes. * design to support both wheels and frame of hike. * select a design that is easy to use. If possible, signs depicting how to operate should be posted. * Offer protection from the weather. See figure 5 for design examples I I 23 I I I C. HOW MUCH MONEY SHOULD BE SPENT ON BICYCLE FACILITY DEVELOPMENT? There is no question that public interest for a Bikeway System is high and ' will increase as facilities are provided. However, is this enough to justify expenditures on bicycle transportation? The following are considerations that might be utilized to support spending. QUALITY OF LIFE - The many benefits associated to bicycle travel such as improved health, reduced air pollution, reduced noise, economy of natural resources, variety of transportation modes, economy of space, and enjoyment of the environment could be utilized to justify the expenditures on bicycle facilities. Unfortunately, these consideration are hard to quantify. EXPENDITURES IN RELATION TO OTHER RECREATIONAL ACTIVITIES - A comparison could be made between participant hours of bicycling versus other participant sports such as golfing, tennis or swimming and a determination made of levels of public expenditures versus hours of public use. A probable result would reveal the bicycle facilities are drastically deficient. INVESTMENT AS A PERCENTAGE OF TRANSPORTATION BUDGET - Since bicycling is a practical mode of transportation, any bicycling facilities should conceivably be included in the transportation planning and development, therefore sharing in the expenditures. During the detailed planning stages of the Bikeway System, location and facility selection will normally involve a cost analysis of alternatives. Funding availability can limit the alternatives; however, it is important that a lack of funds not result in a poorly designed and constructed facility. It is usually more desirable not to construct a bicycle facility than to construct a poorly planned or designed facility. The decision to implement a bikeway plan should be made with a conscious, long-term commitment to a proper level of maintenance. If only a small amount of funds are available, emphasis should be given to low cost improvements such as bicycle parking, removal of certain barriers, existing roadway improvements and non construction projects such as mapping. Sample bikeway construction costs are included in the Specifications section of this report. ' 1 25 , L I ' D. INVENTORY ' Once the general routes for the bikeway system are located and information about the types of facilities and the costs are gathered, detailing the plan can begin. During this stage in the design process many constraints will effect the final '• decisions. A complete analysis of existing conditions will need to be accumulated. Such as: * BARRIERS - Physical barriers caused by topographical features, freeways, or other impediments. The mountainous topography is a major factor for both bicycle ' and pedestrian transportation within the City of Fayettville. * ACCIDENTS - The prevention of bicycle accidents in problem areas. The ' potential for alleviating and preventing accident problems through the selection of facilities should be reviewed. * DIRECTNESS - For utilitarian trips, facilities should connect destination points along the most direct route. ' * ATTRACTIVENESS - The scenic value is particularly important along a facility intended to serve recreational bicyclists and should be considered as an enhancement to the bikeway system. * SECURITY - The potential for criminal acts against bicyclists, especially along remote bicycle paths, and the possibility of theft or vandalism at parking locations ' should be considered. * MAINTENANCE - Maintenance -sensitive design is an important feature. An '• improperly maintained bikeway will often be shunned by bicyclists in favor of a parallel roadway. I C I I Li 26 1J I * PAVEMENT SURFACE QUALITY - Bikeways must he free of humps, holes, and other surface irregularities if they are to attract and satisfy the needs of the bicyclists. Utility covers and drainage grates should he at grade and, if possible, outside the expected area of travel. Approaches to railroad crossings should be improved as necessary to provide for safe bicycle crossings. • ON -STREET VEHICULAR PARKING - The turnover and density of on -street parking can affect bicycle safety (opening car doors and cars leaving angle parking spaces). * TRAFFIC VOLUMES AND SPEEDS - For facilities on roadways, traffic volumes and speeds must be considered along with the roadway width. Commuting bicyclist frequently use arterial streets because they minimize delay and offer continuity for trips of several miles. It can be more desirable to improve heavily traveled, high speed streets then adjacent streets, if adequate width for all vehicles is available. However, improving parallel streets that have few stops and minimal conflicts is preferred in order to accommodate a greater variety of bicyclists. • BRIDGES - Bridges serve an important function by across barriers. However, some features found in bridge bicyclists are to be accommodated. The most common widths that are narrower than the approach roadways, found on movable spans, low railings or parapets, and 4 joints that can cause bicycle steering difficulties. providing bicycle access scan be unsuitable where of these are curb -to -curb open grated metal decks ;ertain types of expansion I * INTERSECTION CONDITIONS - A high proportion of accidents occur at intersections. Facilities should be selected so as to minimize the number of crossing. Wherever intersections occur, the facility must be designed with adequate stopping sight distance. I I I I I 27 ' I As the planning process continues and a comprehensive concept of where the bikeway system should be located is determined, a detailed analysis and inventory of existing conditions will be integral in determining which facilities should be incorporated. Obstructions and impediments on existing roadways along the route, such as unsafe grates, debris, narrow lanes, driveways, rough pavements, high-speed or high -volume traffic, curbside parking, bridge surface conditions, and traffic signals that are not conducive to bicycle travel should be recorded. I V. FUTURE PLANNING Public participation will be essential as we continue the planning process. ' Observations and surveys of active and potential bicyclists will be useful, as will the views of the non -bicycling public. The Bike Route Advisory Committee along with groups and individuals experienced in recreational planning will also be good sources of information, Thus, a wide variety of views should be sought. The National Parks Service, Southwest Region, can offer assistance through the River, Trails and Conservation Assistance Program. Representatives of this program feel that the City of Fayettville and its status as a University town creates favorable conditions for a bikeway system. They may be able to contribute technical assistance to help establish the groundwork for future planning. They may be interested in working with public interest groups and collaborating the efforts of local and state agencies whose involvement will be vital for the success of the hikeway system. MASTER PLANNING - Planning for bicycle facilities must be conducted in conjunction with the comprehensive master plan that strives to fulfill the needs , of the public as Fayettville enters the twenty first century. Plans for implementing bikeway projects must be in harmony with the communities goal for transportation improvements and be considered as a component of their park system. Local ordinances should incorporate future bikeway facilities with all proposed j commercial, industrial and residential development. EDUCATION - Safety must influence all decisions pertaining to bicycle facility development. In view of the considerable danger of riding bicycles on streets with motorized vehicles, a proper educational program must be developed. It is wise that education be implemented before construction on bikeway facilities are completed I LJ 29 ' LJ L r L Li Li I I H I I These are examples of a program designed for the Atlanta Region Bikeway. 1. Expand bicycle education programs in grade schools - From available American Automobile Association statistics, it is clear that by far the highest accident rates are exhibited by grade school children. A high percentage of these accidents were found to be the fault of the bicyclist. To heighten the ability and understanding of school grade children, rodeos could be sponsored to instruct children on bicycle safety. These programs may include a voluntary testing program based on the Bicycle Institute of American Standards. Such a testing program would include balance, pedalling, braking, mounting, maneuvering, stopping, turning, and signalling. 2. Incorporate Bicycle education programs into high school driving education courses - The principal advantage of this would be the education of future drivers in the rights of the bicyclist and the elimination of the need to conduct special programs for bicyclists in this age group. 3. Incorporate special bicycle safety features into driver tests - Since the potential auto driver must share the right-of-way with cyclists, it is important that he understands the rights of the bicyclists in relation to the automobile. •' 4. institute an educational program to police officers - In view of the numerous and confusing local ordinances it is likely that local police officers may not be well informed in regard to bicycle regulations. ' 5. Incorporate bicycling safety suggestions into mass media programming - Make use of radio, television, and newspapers to inform t• and remind both cyclists and motorists of the traffic rules. These media are very effective means of reaching virtually the entire population. I L I I ' 30 I I IMPLEMENTATION - The phasing for construction of the bikeway ' system is an important part of the planning process, and can dictate the momentum and ultimate success or failure of the entire system. The choice of the components for the first phase of the bikeway are crucial. The greater the impact and perceived success of these early stages, the greater the likelihood of continuing and gaining support for the bikeway system. Moreover, each phase of the network, though integrated as a whole, must serve an essential function on its own. In the event of funding being delayed, or even cut off, each completed stage must be exclusively useful so that its resources will not he wasted. ' EVALUATION AND MONITORING - The monitoring and evaluation of any long-term project is crucial to the success of that project. Without feedback and regular evaluation of each phase of the bikeway system, correction of mistakes and adaptation to changing conditions would not be feasible, and could lead to discontinued use or misuse of the hikeway. I I I I C H 1 I 31 I I VI. A CONCEPTUAL PLAN 1 Providing a concept of how a bikeway system and its many components can be tailored to accommodate the needs of bicyclists in Fayettville will supply planners in the future with a basis from which to build a plan. Areas near bicycle traffic generators should be reviewed to identify existing '• Th and potential bicycle travel. The city planning department has noted specific locations that have been identified from public input as priority bicycle traffic generators. These particular areas presently spawn the greatest amount of utilitarian and recreational bicycle trips and should receive significant consideration as the planning process continues. SCHOOLS - a safe access for children from surrounding neighborhoods PARKS - the possible connection between all existing park land and open space. MAJOR EMPLOYERS INCLUDING THE UNIVERSITY - connecting . the work place with residential areas. ' SHOPPING - providing a linkage to residential and major employment centers. RECREATIONAL - noted by the public, involves access to recreational routes that have gained popularity among avid bikers. Some of these routes include Hwy 71 south to Devils Den, Hwy 16W to Lake Wedington, Hwy 112 to Bentonville, and Hwy 265 to Hogeye. Once major bicycle traffic generators are located and a network of logical bicycle ' transportation routes are mapped, the task of inventory will follow. Focus should be on the factors that most influence the needs of bicyclists and the selection of facilities. Several existing conditions hinder the location of many direct routes and effect the selection of preferred facilities. El I I ' 32 U C 1 EXISTING CONDITIONS 1 BARRIERS - The mountains that create the beautiful vistas throughout our city also create the major obstructions to the average bicyclist. Many of our residential areas as well as some of the commercial and industrial districts are developed on, or accessed by, steep slopes that are difficult to travel by bicycle. 1 NARROW STREETS - In older districts of town, within the center, south, and southeast portions of the city, several roadways are 25 feet or narrower. Thus the consideration of adding designated bike lanes should be eliminated. Development within these areas also lack the set -back controls that are currently maintained, resulting in little R.O.W. for widening streets or adding shoulders. ON STREET PARKING - In a majority of locations, on street parking is allowed and frequently used. This becomes an obstacle for bicyclists as well as regular vehicular traffic along the many narrow streets and a hazard to bicyclists even on the wider streets. BRIDGES - The presence of several streams result in conflicts with narrow bridges. The crossing of bridges are the only instance where sidewalks should he used by bikeway traffic. ACCESS - Due to the existing topography, there are numerous residential 1 areas that have minimal access. This results in a deviation from the most preferred routes. PAVEMENT SURFACE QUALITY. - As is expected, rough street surfaces, pot holes, off grade utility covers, inappropriate drainage grates and uneven railroad crossings are present in various locations. I I H H 33 ' I ' Fayettville does possess many qualities that provide the elements for a successful bikeway system. ' ATTRACTIVENESS - The beauty of the Ozark Mountain Region provides a pristine setting for any activity including bicycle transportation. This amenity is not only present along distant vistas but also among the residential neighborhoods where the tree lined streets provide an aesthetic quality to all modes of transportation. EXISTING OPEN SPACE - The concept of using bike paths to connect activity nodes where other facilities are impractical is reasonable along the many utility easements and floodplain areas. ' The analysis of the existing conditions reinforces the concept of using a combination of facilities to provide a continuous bikeway system. The use of bike lanes are the most favored facility and should be implemented as the foundation of the bikeway system while other facilities will be incorporated in locations where bike lanes are not practical or preferred. The following maps show the bikeway locations and the type of facilities suitable for those conditions. Each map graphically indicates the priority bicycle transportation routes, the destinations and the facilities. It is important to note that the location of the routes that were selected to serve a utilitarian purpose may also serve as a connection to, or a section of, recreational routes. The bikeway is a network and serves the needs of several types of cyclists. Segments along a route designated to provide young children with access to school may supply passage to a route that serves the serious recreational rider. I C I ' 34 E E .

WARNING SIGNS Place warning signs approximately 50 to 65 feet in advance of safety hazard situations such as drainage grates, rough surfaces, street crossings, narrow bridge crossing, and other problem situations on bikeways where the warning is strictly for the cyclist. SOURCE: Bikeways: Designo aruction_ Provismc, J BIKE PATH SPECIFICATIONS HORIZONTAL ALIGNMENT AND SUPERELEVATION : ' The minimum radius negotiable by a bicycle is a function of the superelevation rate of the bicycle path surface, the coefficient of friction between the bicycle tires and the bicycle path surface. and the speed of the bicycle. The minimum design radius of curvature can be derived from the following formula: R= L 15(e+t) where: R = Minimum radius of curvature (ft), V = Design Speed (mph), e = Rate of Superelevation, f = Coefficient of Friction. For most bicycle paths applications the superelevation rate will vary from a minimum of 2 percent (the minimum necessary to encourage adequate drainage) to a maximum of approximately 5 percent (beyond which maneuvering difficulties by slow bicyclists might be expected). The minimum superelevation rate of 2 percent will be adequate for most conditions and will simplify construction. The coefficient of friction depends upon speed; surface type, roughness, and ' condition: tire type and condition; and whether the surface is wet or dry. Friction factors used for design should be selected based upon the point at which centrifugal force causes the bicyclist to recognize feeling of discomfort and instinctively act to avoid higher speed. Extrapolating from values used in highway design, design fiction factors for paved bicycle paths can be assumed to vary from 0.30 at 15 mph to 0.22 at 30 mph. Although there are no data available for unpaved surfaces, it is suggested that friction factors be reduced by 50 percent to allow a sufficient margin of safety. ' I I 45 ' I I H I I Ti I Ti Ti I H Ti I I I I C Based upon a superelevation rate (e) of 2 percent, minimum radii of curvature can be selected from Table 3. TABLE 1 Minimum Radii for Paved Bicycle Paths (e = 2 Percent) Design Speed -V (mph) (1 mph= 1.61m/hr) Friction Factor -f f Minimum Radius - R (Feet) (1 ft = 0.3 m) 20 0.27 95 25 0.25 155 30 0.22 250 35 0.19 390 40 0.17 565 Table B When substandard radius curves must be used on bicycle paths because of right of way, topographical or other considerations, standard curve warning signs and supplemental pavement markings should be installed in accordance with the MUTCD. The negative effects of substandard curves can also be partially offset by widening the pavement through the curves. DESIGN SPEED: The speed that a bicyclist travels is dependent on several factors, including the type and condition of the bicycle, the purpose of the trip, the condition and location of the bicycle path, the speed and direction of the wind, and the physical condition of the bicyclists. Bicycle paths should be designed for a selected speed that is at least as high as the preferred speed of the faster bicyclists. In general, a design speed of 20 mph should be used; however,when the grade exceed four percent, or where prevailing tail winds exist, a design speed of 30 mph is advisable. , E I I On unpaved paths, where bicyclists tend to ride slower, a lower design speed of 15 mph can he used. Similarly, where the grades or the prevailing winds dictate, a higher design speed of 25 mph can be used. Since bicycle have a higher tendency to skid on unpaved surfaces, horizontal curvature design should take into account lower coefficients of friction. SIGHT DISTANCE: ' To provide the bicyclist with an opportunity to see and react to the unexpected, a bicycle path should be designed with adequate stopping sight distances. The distance required to bring a bicycle to a full controlled stop is a t function of the bicyclists perception and brake reaction time, the initial speed of the bicycle, the coefficient of friction between the tire and the pavement, and the braking ability of the bicycle. Figure 6 indicates the minimum stopping sight distance for various speeds and grades based on a total perception and brake reaction time of 2.5 seconds and. a coefficient of friction of 0.25 to account for the poor wet weather braking characteristics of many bicycles. For two-way bicycle paths, the sight distance in descending direction, that is, where "G" is negative, will control the design. Figure 7 is used to select the minimum length of vertical curve necessary to provide minimum stopping sight distance at various speeds on crest vertical curves. The eye height of the bicyclists is assumed to be 4.5 feet and the object height is assumed to be zero to recognize that impediments to bicycle travel exist at pavement level. ' Figure 8 indicates the minimum clearance that should be used to line of sight obstructions for horizontal curves. The lateral clearance is obtained by Figure 8 with the stopping sight distance from Figure 6 and the proposed horizontal radius of curvature. I I I 47 ' I I El Bicyclists frequently ride abreast of each other on bicycle paths and, on narrow bicycle path, bicyclists have a tendency to ride near the middle of the path. For these reasons, and because of serious consequences of a head on bicycle accident, lateral clearances on horizontal curves should be calculated based on the ' sum of the stopping sight distances for bicyclists traveling in opposite directions around the curve. Where this is not possible or feasible, considerations should be given for widening the path through the curve, installing a yellow center stripe, installing a curve ahead warning sing, or some combination of these alternatives. BIKE PATH SURFACE MATERIAL: There are several types of surface material that can be used for bike paths, each having their advantages and disadvantages. Unpaved paths are not recommended due to the susceptibility to erosion damage which would make bicycle travel unacceptable. The use of loose materials such as wood chips and gravel is also unadvisable. The texture of these materials make the surface too rough to be acceptable to bicyclists and the slopes that will be encountered within Fayettville exceed the slope recommended for these materials. CONCRETE - An excellent surface for bike facilities, concrete is relatively easy and quick to install. If properly installed with a good base, concrete is extremely durable and maintenance free. ' Concrete should be installed to a minimum depth of 4 inches, however, if the path will be used by maintenance, service or other vehicles it is necessary to provide more reinforcement and pour the concrete at a thicker depth. ' ASPHALT - This material is highly acceptable for many trail uses including bike facilities. Like concrete, asphalt provides a hard durable surface and although it demands more maintenance then concrete, it is slightly less expensive to install. CRUSHED STONE - Crushed stone such as granite and limestone, provides a smooth, sturdy bike path surface. The angular shape of the aggregate tends to compact and interlock better than rounded stone, and combined with finer • particles of clay and other binding materials, the stability of the product is suitable • for trails of grade less than 5 percent. Grades greater then 5 percent may cause the some slumping, and may not be suitable for all bike paths throughout the IFayettville location.
