pedestrian accommodations
What We Have Learned
8

Department of Transportation 9

• Intricate traffic analysis
• Working to arrive at the “Right” solution
• Additional Analysis Undertaken
o Origin-Destination Studies
o Traffic Simulations
Why Is It Taking Longer?
10

• No-Build
• Intersection Improvements
• HOV2+ Lanes – “Inside” option *
• HOV2+ Lanes – “Outside” option *
• General Purpose Lanes *
* These options include the addition of one general purpose lane
in each direction between Guinea Road and Burke Lake Road.
Roadway Improvement Options
11

• Traffic volumes will continue to increase
• Existing congestion points will get worse
• New congestion points will develop

• Improve bottlenecks
Intersection Improvements
15

• What does it mean?
o Controlling travel movements to
balance of access and mobility
• How does it improve the roadway?
o Reduces conflict points
o Facilitates traffic flow
• How does it affect my travel?
o Reduces travel time
o Improves safety
Access Management
16

• Guinea Road Intersection

o Triple NB right turn lane on to Braddock Road
o No NB left or through movement (routed to intersection
via Rolling Road)
o Extend dual left turn lanes on to Burke Lake Road
o Kings Park Drive
limited to right in/
right out

• Options under consideration
o Completed trail network
o Signalized at-grade crossings and HAWK * signals
o Bridges and underpasses
* High Intensity Activated crossWalK beacon
Bicycle and Pedestrian
Accommodations
40

• Connections to neighborhoods and activity centers
• Shared Use Paths along corridor
Completed Trail Network
41

• Crosswalks at signalized
intersections
• Impacts corridor traffic
performance when called
• Allows protected
pedestrian crossings
• Criteria must be met
(MUTCD warrants)
At-grade Crossings HAWK Signals
Department of Transportation 42

• Removes pedestrian/
vehicle conflicts
• High cost
• Improved undercrossing at
Accotink Creek
• Cost-prohibitive at other
locations compared to
other options
Pedestrian Bridges Trail Under-Crossings
43

Important Issues Identified
• Traffic congestion and delays will increase
significantly in the No-build option
• Intersection Improvements help traffic flow
• HOV2+ and General Purpose Lane options require
additional improvements
• Access to/from Transit Sites is critical
• Widening from Guinea Road to Burke Lake Road
needed if widening occurs between Burke Lake
Road and I-495
44

Next Steps
• Finalize Traffic Modeling for Corridor and Analysis of
Alternatives
o Refine build alternatives with addition improvements
o Update traffic analysis and simulations
• Analyze traffic impacts at transit center sites
o Traffic simulation at Kings Park Shopping Center
• Community Meeting – November 2016
• Ranking and Prioritization Final Alternatives
• Develop Preferred Alternatives for Corridor and Transit
Center
