The results of the traffic analysis have been compiled in a report along with observations and recommendations. Roadway cross section recommedations have been made based on the corridor users and proposed land use and densities. The study has also analyzed each intersection and made recommendations for geometry and configuration e.g. traffic signal vs roundabout and has advised of construction phasing options based on project growth in this area. This study will give the City a technical document to develop conceptual road plans to present to the Transportion Committee for approval to move into the design phase. DISCUSSION: A summary of the traffic study inputs and analysis is as follows : • Rupple Road is designated as a Principal Arterial Parkway on the Master Street Plan (City Plan 2030). • Future traffic was generated in the study area by using densities similar to Rupple Row (Traditional/New Urbanism Development Pattern) of 6 .24 units per acre or 1997 units which equates to a 24-hour two-way volume of 19, 111 vehicles at build out. Based on historical traffic volumes, a growth rate of 12% was applied to historic traffic counts outside of the Rupple corridor, but would be utilizing the new Rupple Road. The intersection of Rupple Road and Persimmon Street was evaluated using the year 2033 volumes to determine whether a signalized intersection or a roundabout would operate the more efficiently and safely. In regards to the Level Of Service, the roundabout barely nudged out the signal by 2 seconds which is considered negligible. Therefore, Jacobs decided to recommend and use a signalized intersection in the model in favor of the improved safety conditions for pedestrians, especially within a school zone. • Two future intersections on Rupple south of Persimmon were modeled as roundabouts. • The study analyzed 3 Build Alternatives . o 2-Lane Build from MLK Jr. to south of Persimmon o 4-Lane Build from MLK Jr. to south of Persimmon o 4-Lane Build from MLK Jr. to Wedington Drive THE CITE` OF FAYETTEVILLE,, ARKANSAS Preliminary Study results are as follows : • The 2-Lane Build will operate are very acceptable levels of service the opening year of this facility to traffic. • The first section which will fail operationally or have unacceptable levels of service will be the 2-lane section from Persimmon to Wedington with the Wedington intersection the most problematic due to the significant traffic volumes on Wedington. • The study shows that in the design year 2033 , Rupple Road needs to be a 4-lane facility to provide acceptable levels of service at each intersection/roundabout and acceptable travel times from MLK Jr. to Wedington Drive. RECOMMENDATION : Staff is waiting on the final analysis from Jacobs which will determine how many years from now will the four lane facility need to be constructed. Based on this answer, staff would either recommend to build 4 lanes now or wait and only build a two lane roadway at this time. If a two lane roadway is recommended, then we need to look at how to build the two lane roadway with expansion in mind as well as access management. Staff has drafted two typical sections, Option 1 and Option 2 (attached) to review and discuss with the Transportation Committee. ................ .............. ....... ............ ................ ....................... ............................................. .......................................................:.......<........................ ................................................ gas .5' C&G 1.5" C&G 12 10 lit 10 ............... .................... ............................... ............. .......... ......

The study area also included the existing section from Persimmon Street to Wedington Drive. The study area is shown in Figure 1. +i ■ Figure 1. Study Area Currently Rupple Road in the study area extends south from Wedington Drive to just south of the Owl Creek Elementary/Middle School. There is a traffic signal at the intersection with Wedington Drive and a 4-way stop at the Persimmon Street intersection. Rupple Road does not exist between the school and MLK (Hwy 62). The Master Street Plan (City Plan 2030) designates Rupple Road as a principal arterial parkway. The typical section for principal arterials obtained from the Master Street Plan is shown in Figure 2. For the study, parking was not included in the analysis. 21 Page PRINCIPAL ARTERIALS WITH ON-STREET PARKING are intended to be used in compact urban environments that are highly walkable and where building entries front the street. This street section is not intended to be used where traffic speeds exceed 30 MPH, 7 PRINCIPAL ARTERIAL BOl1LEVARD (WITH PARKING): Design Service Volume: <17,600 vpd 7 Desired Operating Speed: 25-10 mph .

Master Street Plan —Street Section Study Process: The step by step study process that we have used in this study is: 1. Collected the existing information in and around the study area. 2. The turning movement counts were collected from two (2) intersections(Rupple Road/Wedington Drive and Rupple Road/Persimmon Street). Turning movement counts were collected on a Tuesday and a Wednesday in October and November, 2013. 3. Radar counters were used to collect 24 hour counts at strategic points on the road network around the campus as shown in Figure 3. 4. The City of Fayetteville provided the future zoning information for the study area (see Table 4). 31 Page ow ., LEGEND WEDIPATON DRIVE 7 r* . t .'I'vr ,'e 24 HOUR COUNT LOCATIONS AIM r RUPPLE ROAD PERSIMMON STREET ' A 1-540 �k v STV 15 F .. a.r.: ir * r RJ �. ■ L ]LIM LL JW MLK BOULEVARD � 4 I 5. Jacobs has collected some information from other sources: a. Signal timings from City of Fayetteville. b. Average Daily Traffic (ADT's) from the Arkansas Highway and Transportation Department (AHTD) website. 6. Development of VISSIM and Synchro base models for the study area. 7. Development of future traffic numbers based on the historical traffic counts in the area as well as future development of the area along the corridor using the future zoning information provided by the City. 8. Analysis and calibration of the existing traffic in the base models. 9. Analysis of the future alternatives. 10. Summary of results and findings. After collecting the data a base traffic model was developedfor the analysis. The modeling software that is used on this project is VISSIM. VISSIM is microscopic time step driver behavior traffic simulation software, developed to model urban traffic (vehicle and pedestrian) and public transit operations. The program analyzes traffic and transit operations under constraints such as lane configuration, traffic composition, traffic signals, transit stops, etc.,thus making it a useful tool for the evaluation of various alternatives based on transportation engineering and planning measures of effectiveness (MOE's) such as vehicle delay, travel times and queue lengths. This program is capable of implicitly modeling passenger vehicle, light rail transit (LRT) vehicle and pedestrians simultaneously and also offers great visualization from simple to complex traffic conditions to provide a realistic picture of the traffic operations. Level of Service Level of service (LOS) is a term defined in the Highway Capacity Manual (HCM) to describe the operating performance of an intersection or roadway. The LOS of an intersection is a qualitative measure of capacity and operating conditions and is directly related to vehicle delay. LOS results range from "A" (minimal delay and conflicts) to "F" (significant delays and congestion), with LOS A representing very short delays and LOS F representing very long delays. As a practical consideration, LOS D is considered the limit of acceptable operation in an urban environment. LOS C is the desirable condition. LOS conditions for signalized intersections are shown in Table 1. For unsignalized intersections, the levels of service are shown in Table 2. The graphical representation of each intersect on LOS category is displayed in the below Figure 4. 51 Page Table 1. Level of Service Criteria for Signalized Intersections Level-of-Service Average Control Delay (LOS) (seconds/vehicle) Description A <_ 10.0 Very low vehicle delays, free flow, signal progression extremely favorable, most vehicles arrive during given signal phase. B 10.1 to 20.0 Good signal progression, more vehicles stop and experience higher delays than for LOS A. C 20.1 to 35.0 Stable flow, fair signal progression, significant number of vehicles stop at signals. D 35.1 to 55.0 Congestion noticeable, longer delays and unfavorable signal progression, many vehicles stop at signals. E 55.1 to 80.0 Limit of acceptable delay, unstable flow, poor signal progression, traffic near roadway capacity, frequent cycle failures. F >80.0 Unacceptable delays, extremely unstable flow and congestion, traffic exceeds roadway capacity, stop-and-go conditions. Source:HCM 2010 Table 2. Level of Service Criteria for Unsignalized Intersections Level-of-Service Average Control Delay (LOS) (seconds/vehicle) Description No delays at intersections with continuous flow of traffic. A < 10.0 Uncongested operations: high frequency of long gaps available for all left and right turning traffic. No observable queues. B 10.1 to 15.0 Same as LOS A Moderate delays at intersections with satisfactory to good traffic C 15.1 to 25.0 flow. Light congestion; infrequent backups on critical approaches. Increased probability of delays along every approach. Significant D 25.1 to 35.0 congestion on critical approaches, but intersection functional. No standing long lines formed. Heavy traffic flow condition. Heavy delays probable. No available E 35.1 to 50.0 gaps for cross-street traffic or main street turning traffic. Limit of stable flow. Unstable traffic flow. Heavy congestion. Traffic moves in forced F > 50.0 flow condition. Average delays greater than one minute highly probable. Total breakdown. Source:HCM 2010 61 Page Figure 4—Level of Service Descriptions LOS Intersections A No vehicle waits longer than one signal indication. B On a rare occasion, vehicles wait through more than one signal indication. C Intermittently, vehicles wait through more than one signal indication, occasionally backups may develop, traffic flow still stable and acceptable. 7. D Delays at intersections may become extensive, but enough cycles with lower demand occur to permit iF periodic clearance, preventing excessive backups. Wilor ; E Very long queues may create lengthy delays. ZU 4�� F Backups from locations downstream restrict or prevent movement of vehicles out of approach creating a �? "gridlock" condition. 7Page Existing Traffic The existing traffic data collected for the study area are summarized in the tables below. The traffic data counts are in the appendix. Overall, the AM traffic counts represent higher peak hour volumes for the study area and are, therefore, the focus of the analysis.

Fayetteville Planning provided two densities for residential zoning in the area. Table 4—Future Zoning in Study Area Fayetteville Planning Type Density Mountain Ranch Typical Suburban 1.95 units per acre Development Rupple Row Traditional/New Urbanism 6.24 units per acre Development Pattern The future zoning area is approximately 1 mile long by a half mile wide or 320 acres. Which would provide approximately 1997 units with the higher density or 624 units for the lesser density. For this study, 1997 units were used.

Table 8—Persimmon Street Intersection Delay Comparison Scenario Delay LOS (sect Roundabout 9.3 A Signalized Intersection 11.3 B 13Page Both scenarios have a low overall intersection delay. Given the negligible difference in overall delay, it was decided to model the intersection of Rupple Road and Persimmon Street as a signalized intersection in VISSIM to provide improved safety conditions for pedestrians. VISSIM Analysis Three (3) horizon year models were created within VISSIM. These models consisted of an Existing Year 2013, Opening Year 2013, and Design Year 2033 scenarios. The Existing Year 2013 model has the existing geometry for Rupple Road including the intersections of Wedington Drive and Persimmon Street. The Existing Year model was calibrated using traffic volumes and travel times collected in October and November 2013. The targets of this calibration effort were obtained from the Traffic Analysis Toolbox Volume 111— Guidelines for Applying Traffic Microsimulation Modeling Software published by the Federal Highway Administration (FHWA) and shown in the figure below.

This measure is a formula used in traffic modeling to compare two sets of traffic volumes (Observed and Modeled). Its mathematical formulation is similar to the Chi-Squared test, but it is not a true statistical test but rather an empirical formula. The formulation for the GEH Statistic is as follows: 2 * (M - 0)z GEH = (M + 0) Where M represents model estimate volume and O represents field counts. This statistic is typically used to offset the discrepancies that occur when using only simple percentages, as traffic volumes vary over a wide range. In other words, if using only percentages, small absolute discrepancies have no impact on large volumes but a large percent impact in smaller numbers, and vice versa. It has been shown that for traffic volumes smaller than 10,000 a five percent variation yields smaller numbers than a GEH of five. Beyond 10,000, five percent differences keep growing linearly whereas GEH=5 follows a decaying curve. The tables below summarize the calibration results in terms of GEH values and link flows for the AM peak period model. The results indicate that the model satisfies the volume calibration criteria listed above.

Of the field collected travel times provided, only one of the segments fell within the section of Rupple Road being modeled in the Existing Year model. This segment, specifically southbound Rupple Road from Wedington Drive to Persimmon Street, had an average field collected travel time of 83 seconds, this time is used to help calibrate the Existing Year model. The travel time for this segment within the Existing Year model was also 83 seconds. The detailed volume and travel time calibration spreadsheets are included in the appendix for further reference. For the Design Year 2033 VISSIM analysis the following geometry assumptions were made: • Rupple Road would curve west shortly after the existing southern terminus before traveling directly south to Martin Luther King Jr. Boulevard • The two proposed roundabouts between Persimmon Street and MILK Boulevard would have approximately equal spacing between them. The intersecting east-west roadways were assumed to be two-lane undivided facilities. • As determined based upon the Synchro analysis, the intersection of Rupple Road and Persimmon Street would be modeled as a signalized intersection. 161 Page W--] edin on Dr i h• x Persimmon St Roundaboutl L { 4 u v^ c RoundabouU C. MILK Blvd Figure 8— Rupple Road Extension VISSIM Model 17Page The following three (3) Build Alternatives were analyzed: • 2-lane Build:Two-lane Rupple Road extension:This alternative provides a 2-lane roadway between Martin Luther King Jr. Boulevard and the existing 4-lane southern termini south of Persimmon Street,thereby providing a 2-lane facility between Martin Luther King Jr. Boulevard and Wedington Drive,with the exception of the existing 1,300 foot 4-lane segment south of Persimmon Street. • 4-lane Build: This scenario provides a four lane roadway between Martin Luther King Jr. Boulevard and the existing 4-lane southern termini south of Persimmon Street. Under this scenario, Rupple Road between Martin Luther King Jr. Boulevard and Persimmon Street has a 4- lane section that reduces to a 2-lane facility at Persimmon Street. • 4-lane to Wedington Drive Build Alternative:This alternative would provide a 4-lane facility from Martin Luther King Jr. Boulevard to Wedington Drive, eliminating the choke point which occurs when the roadway reduces from four lanes to two lanes at Persimmon Street. This alternative will require widening between Persimmon Street and Wedington Drive. Additional improvements also proposed under this scenario include: o Persimmon Street intersection: Modifying the northbound right turn lane into a shared thru-right turn lane o Wedington Drive intersection: Modify the northbound approach to include exclusive left turn lane, through lane and exclusive right turn lane with overlap phasing. o Wedington Drive intersection: Modify the southbound right turn lane to a shared thru- right turn lane. The alternatives were evaluated using opening year and design year demand volumes, with the exception of 4-lane Build to Wedington Drive alternative which was only analyzed for Design Year 2033. Average vehicle delay at each intersection, corridor travel times, and network-wide performance measures (i.e.,total process volumes, latent demand,total delay time, and average speed)were extracted from the VISSIM models to assess the performance of each alterative. Summary of Results and Findings One of the objectives of this analysis was to determine if and/or when the proposed segment of Rupple Road, extending from the current terminus south of Persimmon Street to Martin Luther King Jr. Boulevard,would need to be expanded from a two-lane roadway to a four-lane roadway. After analyzing the proposed segment of Rupple Road modeled as a two-lane roadway, it was determined that, although a two-lane facility appears to be operate satisfactorily under opening year demand conditions, a two-lane facility would not have sufficient capacity to accommodate the design year demand. Severe congestion was observed throughout the corridor in the Year 2033 2-lane Build microsimulation model. As shown in Table 12, an acceptable level of delay was observed at all intersections for both the 2-lane and 4-lane Build alternatives during opening year; whereas,Table 13 shows the intersection delay at several intersections increases considerably as a result of the increase in 181 Page traffic volume expected in Year 2033 and lack of intersection capacity under the 2-lane and 4- lane alternatives.The results also indicate that delay along the corridor is substantially decreased when Rupple Road is widened from two to four lanes between Persimmon Street and Wedington Drive. Under the improved 4-lane scenario, intersection delays are less than 25 sec/veh,with the exception of the intersection at Wedington Drive which experiences a significant delay on the eastbound approach.
