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

Department of Transportation 45
Next Steps• Finalize Traffic Modeling for Corridor and Analysis of
Alternativeso Refine build alternatives with addition improvementso Update traffic analysis and simulations
• Analyze traffic impacts at transit center siteso Traffic simulation at Kings Park Shopping Center
• Community Meeting – November 2016• Ranking and Prioritization Final Alternatives• Develop Preferred Alternatives for Corridor and Transit
