TRANSPORTATION COMMITTEE MEMO Meeting of February 24,2014
To: City of Fayetteville Transportation Committee
From: Chris Brown, City Engineer
Date: February 21, 2014
Subject: Rupple Road Traffic Study Discussion—MLK Jr. Boulevard to Wedington Drive
BACKGROUND:
Jacobs Engineering Group was hired to perform a traffic impact analysis of both existing and future sections
Rupple Road from MLK Jr. Blvd. to Wedington Drive. 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, growth rates from 1.2% to 1.9% were applied to historic traffic
counts outside of the Rupple Road corridor (background traffic) that 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 recommends, and used 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 Road south of Persimmon Street were modeled as roundabouts.
• The study analyzed 3 Build Alternatives:
0 2-Lane Build from MLK Jr. to south of Persimmon Street
0 4-Lane Build from MLK Jr. to south of Persimmon Street
0 4-Lane Build from MLK Jr. to Wedington Drive
THE CITY OF FAYETTEVILLE,ARKANSAS
Final 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 Street 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.
• The study states that a 2-lane roadway should operate with acceptable delays and speeds until the
corridor is developed to approximately 50% to 75% of build out which could occur in 10 years given the
need for the north-south connection, the close proximity to the school, Boys & Girls Club and I-540.
Staff developed cost estimates (rough order of magnitude) for three different road cross sections (attached) in
the following table:
Road Cross Section Est.Cost Dollars Saved Percentage Saved
Option 1 2-lanes west side only depressed median, 12'trail $5.67 Million -$1.70 Million -23%
Option 2 2-lanes depressed median, gravel shoulders, 12' trail, 5' $6.67 Million -$0.70 Million -10%
s/w
Full Option 4-lane boulevard w/ 12'trail& 5'sidewalk $7.37 Million
RECOMMENDATION:
Considering the relative closeness (for projects of this magnitude) of the above construction estimates, the
difficulty of access management without the median in place, the lack of major alternate routes for citizens,
staff recommends moving forward with the Full Option. If the Committee chooses a phased approach, Option 1
is preferred over Option 2 due to the relative ease of constructing the additional lanes in the future.
If Option 1 is chosen, the intersection at Wedington needs to be widened out to full width to accommodate the
heavy northbound right turn on to Wedington and the intersection at Persimmon Street will also have to be
widened to provide increased safety with the installation of the new traffic signal. Because of these needed
improvements and considering that there exists a short section of 4-lane Rupple Road south of Persimmon
Street, staff recommends 4-laning this entire segment of Rupple Road from the Persimmon Street intersection
north to Wedington. The traffic study also identified this segment as the first to fail from increased traffic
volumes. The cost of widening between Persimmon Street and Rupple Road was not considered in the cost
analysis since this work is recommended to be completed in either case.
Regardless of whether the 4-lane option or the 2-lane option is chosen, staff recommends:
1) Signalization at Persimmon Street and Rupple Road.
2) Construction of roundabouts at the 2 planned collector streets intersecting Rupple Road.
3) Full width construction from MLK Jr. Blvd. to the Farmington Branch of Goose Creek crossing.
4) Widening Rupple Road to 4-lanes between Persimmon Street and Wedington, as noted above.
Once direction is provided from the Transportation Committee, staff will proceed with design and other project
development tasks.
