The Fairfax County Department of Transportation completed the Countywide Transit Network Study in 2016, in an effort to determine the type of transit systems needed to accommodate desired economic growth throughout the county over the next several decades. 

The study developed recommendations for where Metrorail should be extended, where light-rail or bus rapid transit systems are appropriate, and where express bus connections would help meet the transportation needs of future growth. The purpose of the Countywide Transit Network Study is to establish a network of high quality transit corridors in a cost-effective way to serve the county’s needs to accommodate planned growth over the long term.

FCDOT, in coordination with VDOT, is conducting a multimodal corridor study for the Fairfax County Parkway (Route 286) from Route 7 (Leesburg Pike) to Route 1 (Richmond Highway). The study corridor is approximately 31 miles in length and consists of 83 intersections and 17 interchanges.

There is a short-term and a long-term component of the study. The short-term study, which is being led by VDOT, is evaluating existing and short-term traffic conditions and will develop multi-modal recommendations to address existing and projected operational issues along the corridor. This project will assess short-term multimodal improvements that can be implemented immediately or within the next five to ten years to address operational and safety issues.

The purpose of the Herndon Metrorail Stations Access Management Study (HMSAMS) was to engage the public to identify and prioritize necessary bicycle and pedestrian facility projects to improve access to the future Herndon and Innovation Center Metrorail Station, culminating in the production of Station Access Manage Plans for each station. The effort was led by the Fairfax County Department of Transportation (FCDOT), was guided by a diverse 16 member HMSAMS Advisory Group, was supported by a consultant team and included three public workshops as well as an interactive, online survey. The HMSAMS public outreach process resulted in the participation of approximately 275 Fairfax County or Town of Herndon residents.

The purpose of this study is to address the recurring congestion on Hunter Mill Road from Sunrise Valley Drive to the Colvin Run Bridge during the morning and evening peak hours. The congestion is heavily concentrated at the intersections of Sunset Hills Road and the westbound Dulles Toll Road ramps at Hunter Mill Road. These two intersections are closely spaced and constrained by the existing bridge. The number of vehicles using Hunter Mill Road is forecasted to increase in the future.

With the opening of the Wiehle-Reston East Metrorail station, new development anticipated in Reston, and an increase in background traffic associated with development elsewhere in the region, vehicular traffic is expected to increase in this area. This study will look at alternatives to mitigate the existing and future conditions to ensure traffic can move efficiently through the intersections.

The study identifies intersection improvements that enhance the intersection operations and increase capacity, specifically through Silverbrook Road’s southbound left-turn movement and Lorton Road’s westbound right-turn movement. In addition, the goal of the study is to address any safety or operational deficiencies found through the existing conditions analysis, and address any other modes of transportation needs.

After considerable community involvement, the Fairfax County Department of Transportation (FCDOT) has developed a Preferred Recommended Design Alternative for the North Kings Highway (VA 241) Corridor within the Penn Daw Community Business Center (CBC). This alternative, Option 8C-1, addresses traffic issues and community concerns, including cut-thru traffic, pedestrian safety and walkability in the area. FCDOT will now initiate project design and will have further community involvement as the design progresses.

The Purpose of the network analysis, as directed by the Board of Supervisors, is to evaluate the conceptual grids of streets and road elements at gateways to the Reston Transit Station Areas (TSAs), which would result in traffic flowing at acceptable conditions while maintaining a walkable grid of streets. The end result should be TSA street networks that are cost effective, and require the minimum right-of-way, with the least negative impacts to adjacent properties and the environment and take into consideration the provisions of the Reston Phase I Master Plan. These improvements will mitigate problem locations in the three TSAs.

The Route 7 Bus Rapid Transit (BRT) Study intends to provide details on how a BRT system would function in Tysons from Spring Hill Metrorail Station to the I-66 interchange. The project team is currently developing and testing alternative BRT alignments in Tysons. The team is anticipating presenting the results and recommendations for potential alignment along with station locations in Fall 2020 to gain feedback and comments from the public.

FCDOT is commencing a phasing study to develop recommendations on the projected order in which transportation improvements should be implemented to maintain a balance between the future development of Seven Corners and the associated transportation infrastructure over time. The improvements were recommended in the Seven Corners Comprehensive Plan Amendment, which was adopted in 2015.

As part of the Tysons Neighborhood Study, the Fairfax County Department of Transportation (FCDOT) has identified the need to improve the Spring Hill Road and Lewinsville Road signalized intersection. The intersection has a significant skew and experiences peak hour congestion, significant cut-through traffic, long queues, and has a documented crash history. The project will develop and evaluate various preliminary concepts to improve intersection traffic operations and safety for all modes. A preferred alternative will be selected based on a comprehensive evaluation process of the project measures-of-effectiveness (MOEs) and community feedback.

In June 2010, the Fairfax County Board of Supervisors adopted a new Comprehensive Plan for Tysons Corner to take advantage of the arrival of Metrorail service to Tysons and transform the area from the auto-oriented, suburban development pattern that exists today into a true urban downtown for Fairfax County. The Tysons Plan calls for a walkable, pedestrian and bicycle friendly Tysons that will eventually be home to 100,000 residents and 200,000 workers. While the Tysons Plan outlines a long-term vision for Tysons, it does not provide a multimodal access management plan to address near term access to the Metrorail stations in Tysons Corner.

In order to create a multimodal access management plan for the Metrorail stations, currently under construction, in Tysons Corner, as well as to get the public to begin thinking about how they will reach the stations, the BOS approved funding for the Tysons Metrorail Station Access Management Study (TMSAMS) project on June 1, 2009. The ultimate objective of the study was to create a document that can be used as a tool for the BOS to make funding decisions on multi-modal transportation improvement projects, specifically to access the Metrorail stations in Tysons Corner, as funding becomes available.

As Fairfax County moves ahead to develop a plan for station access management and traffic improvements at the Wiehle Avenue Metrorail station, significant input from the public and identified stakeholders will be solicited and considered. A project advisory committee, known as the Reston Metrorail Access Group (RMAG), was appointed by Fairfax County Supervisor Catherine M. Hudgins in the spring of 2006 and was convened in July. At that meeting, the group reviewed information presented by Richard Stevens, the Fairfax County Department of Transportation Project Manager for the Dulles Rail Project.
