Town of North Wilkesboro Downtown Traffic Study


The City of Charleston planned to improve and expand the existing Gaillard Municipal Auditorium into what will be an attractive, multi-functional civic center at the heart of historic Charleston, to be named Gaillard Center. DAVENPORT was retained to provide transportation engineering services for the proposed center to determine the potential transportation related impacts of this development and to identify improvements required to accommodate the impacts of both background and new development traffic. DAVENPORT worked closely with the City to obtain background information and develop the scope of work which included traffic and pedestrian counts, intersection analyses, and operational review of existing parking deck gates.

The project was located on Calhoun Street, an area already prone to having queuing and parking issues. In addition, right-of-way constraints would not allow for traditional roadway improvements. Also, the City had estimated the each month of delay would cost an additional $366,000, and therefore were anxious to gain project approval as quickly as possible. It was also important to the city to gain the approval of the surrounding residents.

Due to the location of the proposed redevelopment and an extremely tight site, cost effective roadway improvement options were limited. Taking this into account, DAVENPORT was able to develop creative and budget-friendly congestion and parking strategies. DAVENPORT was also able to meet the tight deadline requested by the City. The report DAVENPORT delivered addressed the concerns of the surrounding neighborhood with regards to transportation. This allowed the city to gain project approval, move the development forward, and take advantage of lower construction costs.

The Gaillard Center project is currently under construction.



The intersection of South Church Street and Williamson Avenue/St. Marks Church Road is located on the western side of Burlington. The city had identified this intersection as one of its most congested, and it was expected to worsen in the future. With a population exceeding 55,000 residents and growing, the City of Burlington sought to improve traffic conditions to provide capacity for future growth, and improve safety.

DAVENPORT performed a thorough review of this intersection, including traffic data collection and field observation, level of service and queuing analysis, crash analysis, recommendations, conceptual designs, and cost estimating. The purpose of this effort was to identify improvements that could be made in the short term and long term.

DAVENPORT's Solution

Applying today’s standards to an already established intersection with intense development on all four corners required creative solutions. Limited right-of-way, multiple access points for adjacent developments that did not meet current access management standards and numerous above and below ground potential utility conflicts provided for a unique challenge for our team. DAVENPORT worked with all stakeholders for the project, and ultimately delivered a cost effective plan that could provide a roadmap to improving this intersection, both in the short term and in the long term.



As part of the City of Greenville’s revitalization plan for its Uptown Commercial District, a new four-story, 250-space parking deck was planned on the southwest quadrant of the intersection of 4th Street and Cotanche Street. DAVENPORT was selected as part of the design team to provide transportation engineering support services. DAVENPORT’s role included a transportation impact analysis to determine what, if any, intersection or roadway improvements would be needed. Analysis included traffic modeling for the project’s build year, as well as a future scenario for five years after the parking deck was planned to open to the public. The traffic study included the two access driveways proposed for the parking deck and multiple other off-site study intersections. DAVENPORT evaluated level of service for all study intersections and provided a detailed vehicular queuing analysis to ensure proper function of the parking deck access driveways and surrounding intersections. DAVENPORT’s team coordinated our scope of work closely with the City of Greenville Traffic Engineer.



DAVENPORT was retained to upgrade and modernize the existing traffic signal at the intersection of W. Broad Street and N. Allison Street in Richmond, VA. The upgrades included:



The City of Winston Salem selected DAVENPORT to determine the feasibility of adding bicycle lanes to the South Main Street Corridor. This is part of the City’s plan to make its facilities more multimodal.

As a result of the feasibility study findings, DAVENPORT designed bike lanes for Main Street from Salem Avenue to Clemmonsville Road, and for Acadia Avenue (Salisbury Ridge Road) from Buchanan Street to Sunnyside Avenue. In lieu of adding an additional lane which would have cost significantly more, DAVENPORT modified the existing lanes to accommodate 5-wide bicycle lanes while maintaining traffic lane regulations. Where the available pavement was too narrow for a separate 5’ wide bicycle lane, DAVENPORT established markings that indicated shared lanes. DAVENPORT also revised the existing signal design to accommodate the addition of bicycle lanes. This included both directions on Main Street and eliminating one of the two northbound left turn lanes. DAVENPORT also provided traffic signal design modifications to accommodate the dual direction bicycle lanes on Main Street at the intersection with Silas Creek Parkway. The designs met NCDOT standards and were review by WSDOT and NCDOT. DAVENPORT’s construction document package received minimal review comments.

DAVENPORT completed professional services for this project in 2010, with the City of Winston-Salem implementing our design in 2013.



The Town of North Wilkesboro desired to have a more walkable downtown. DAVENPORT was hired to perform a corridor study to help analyze downtown traffic patterns in order to make recommendations on how to make the area more walkable. DAVENPORT provided traffic forecasting, traffic analysis, traffic simulation, and cost estimates.

After extensively reviewing the various alternatives, DAVENPORT suggested the Town convert the most trafficked corridor from a one-way street to two-way traffic. DAVENPORT’s recommendations also outlined access management, traffic circulation, traffic control, signal timing, phasing, safety, transit, parking and constructibility. Replacing an existing traffic signal with a four-way stop was also recommended in order to create a “town center” feel.

The Town and NCDOT accepted these recommendations and ultimately installed them resulting in a more pedestrian friendly downtown.

Before After



DAVENPORT was commissioned on September 8, 2009 by the Piedmont Area Transit Authority (P.A.R.T.) to prepare a preliminary development plan and subsequent construction documents for the development of a Park and Ride facility on a 1.5 acre vacant parcel in the Town of Mocksville, NC. DAVENPORT was also commissioned to obtain approval of the erosion & sedimentation control plan, solicit bids and provide construction support services for the development. Despite already being late in the year, P.A.R.T. wished to start construction before the end of the year. DAVENPORT rose to the occasion with expedited design and permitting efforts, issuing construction documents (including plans and project manual) for bid on October 23, 2009. Bids were opened November 4, 2009, less than 60 days from DAVENPORT’s Notice to Proceed!

DAVENPORT’s scope of work included the preparation of site design to include parking for 122 vehicles and a bus patron shelter. The site plan accommodated a paved centralized patron gathering area with adjacent handicap parking, landscape buffers and decorative fencing. The construction documents included a topographic survey (by others), a site plan, grading and drainage plan, site lighting & landscaping plan, erosion & sedimentation control plans. Permitting included DENR erosion & sedimentation plan approval and Town of Mocksville zoning and grading permits.

As part of our bid and construction support services on the project, DAVENPORT prepared and issued bid packages, conducted a pre-bid meeting, attended the bid opening at P.A.R.T. offices, and assisted with the evaluation of bids to identify the apparent low bidder. We also performed periodic construction observations to process pay applications and ensure substantial compliance with the construction documents.



DAVENPORT was retained by the Capital Area Metropolitan Planning Organization (CAMPO) to perform a hot spot study for the intersections of US 401 at Ten-Ten Road, and US 401 at Hilltop-Needmore Road. The intersections, located south of Raleigh along the US 401 corridor north of SR 42, were experiencing significant delay and operational deficiencies. Traffic was anticipated to increase at these intersections with the expected continuation of growth in the surrounding area. Long-range plans were in place by NCDOT to eventually widen the roadway to six lanes with a superstreet configuration. DAVENPORT was tasked with identifying interim improvements to improve safety and operation of the intersections until such time as the roadway widening project moved forward.

DAVENPORT’s team assessed the intersections to determine existing and future conditions to aide in identifying feasible and low-cost solutions to improve the operations and safety of the intersections. Future year analyses were carried out for short-term conditions in 2020 and long-term conditions in 2040. The improvement options were assessed for their ability to improve the level-ofservice at the intersection, as well as having minimal impacts to natural and cultural resources. Planning-level cost estimates were also prepared for each improvement option.

DAVENPORT’s Solution
The existing traditional intersection designs had proved ineffective, unsafe, and operationally deficient. After close communication with CAMPO and NCDOT, DAVENPORT recommended non-traditional solutions for both intersections.

For US 401 at Ten-Ten Road, DAVENPORT’s solution involved a Michigan Lefts intersection treatment as well as a single quadrant loop on the northeastern quadrant of the intersection. For the US 401 at Hilltop-Needmore Road, DAVENPORT recommended a reverse superstreet concept along with relocating Hilltop Road further to the south and connecting to Lake Wheeler Road. In addition a superstreet configuration was recommended for the intersection of Lake Wheeler Road with main street left turns permitted. These improvement options provided for the best operations and level of service for both short- and long-term scenarios, while improving the safety of the intersections by reducing conflict points.
