Maryland Transportation System Performance Dashboard 2016 Annual Attainment Report Highlights

 Goal: Community Vitality   


  • Better coordinate transportation investments and land use planning to support the environmental, social and economic sustainability of Maryland's existing communities and planned growth areas.
  • Enhance transportation networks and choices to improve mobility and accessibility, and to better integrate with land use.
  • Increase and enhance transportation connections to move people and goods within and between activity centers.

Select a Measure:

What We Measure:

Percent of vehicle miles of travel (VMT) in congested conditions on freeways/expressways and arterials in Maryland during the evening peak hour.

Why We Measure:

This measure tracks SHA performance in reducing congestion on the state highway system.  This is an indicator of congestion and the people/vehicles impacted by congestion.

Performance Progress:

  • Continued mobility/congestion management initiatives
  • The 2013 to 2014 increase in the percent of Vehicle Miles Traveled (VMT) experiencing congestion on freeways/expressways in evening peak hour could be attributed to the steadily improving economy that has resulted in increased peak hour VMT in the last few years, as the improved job market appears to be contributing to increased commuter travel
  • Work zones related to capital projects like the MDTA I-95 ETL project and other system preservation projects around the state also impacted the peak hour operations on freeways and expressways
  • Percent of VMT experiencing congestion on arterials in evening peak hour remained at very similar levels between 2013 and 2014. This could be attributed to the relatively flat demand on the arterial system, local intersection improvement projects, additional data coverage on local arterials and rounding methods

Future Strategies:

  • Develop and implement low-cost geometric improvements to alleviate congestion hotspots on the arterial system
  • Continue to work on long-term multimodal solutions that enhance safety, mobility and reliability of the arterials including some bus rapid transit (BRT) projects
  • Continue signal retiming and optimization program to improve arterial operations
  • Develop short-term congestion management solutions (geometric improvements, incident management, special event planning and ITS strategies) to improve traffic operations on freeways/expressway systems
  • Incorporate strategies that improve reliability of the transportation system. SHA will look at implementing Transportation Systems Management and Operations (TSM&O) strategies to improve mobility and reliability
  • Work on long-term multimodal solutions that enhance safety, mobility and reliability of the transportation system
