As shown in the scroll plan as shared in the public meeting, the current intersection of Route 221 with Old Forest Road / 501 Expressway is a "conventional" intersection with a phase signal operation. This means, for instance, that the traffic signal controls the intersection in a manner per the following:
Between phase changes, there are periods of yellow and all-red time, which result in a significant amount of time when nobody is moving.
With the new scheme, the two intersections (southbound 501/221 and northbound 501/221) will operate with only three signal phases. This will include:
The advantage of fewer phases is that there is less "lost time" for each signal cycle due to signal phase changes. See this link for more information: Innovative Intersections and Interchanges - Info/Virginia Department of Transportation.
Additionally, as noted at the link, there are other safety benefits with this "innovative" intersection configuration.
The current left turn count shows 8 vehicles in the morning and 12 vehicles in the PM peak hours making that turn. Our projections for the year 2045 show 10 vehicles in the AM and 15 vehicles in the PM peak hours. Under the new configuration, those projected left turns will have to re-route as discussed in the public meeting. If all of the vehicles choose to use Wiggington, a maximum of 15 vehicles as currently anticipated, would equate to one vehicle every 4 minutes. However, if the Wiggington/Old Forest Road intersection becomes more congested in the future, motorists could choose to use the "circular" route as described in the public meeting.
To improve pedestrian and bicycle safety the city is providing a shared-use path along both sides of U.S.-501 N between U.S.-221 and Old Forest Road. Shared use paths are paved facilities physically separated from motorized vehicular traffic by an open space or barrier and are either within the highway right-of-way or an independent right-of-way. Shared use paths are used by bicyclists, pedestrians, skaters, runners, and others.
Current pedestrian counts do not warrant a pedestrian bridge/tunnel at any of the three intersections.
Roundabouts were considered during the Conceptual Design and Environmental assessment phases and determined to not meet the traffic demand required.
