1 Congestion Management System in Hampton Roads, Virginia Presented by: Keith Nichols Hampton Roads Planning District Commission CMS Peer Exchange Forum September 16, 2005 The Hampton Roads Region Located in SE Virginia 10 cities and 6 counties, including Virginia Beach, Norfolk, and Williamsburg Over 1.6 million residents Economy driven by the military, ports, and tourism Connected by bridges/tunnels 1

2 Joins Map 9 Peninsula North Joins Map 13 Southside West Joins Map 15 Southside East CMS Data CMS network includes all minor arterials and above, as well as selected collectors Over 1,500 roadway segments (1,300 centerline miles) CMS network = Long range planning network CMS database includes various traffic characteristics for each roadway segment Daily volumes Roadway characteristics Peak hour data Truck data Travel time data GIS data Congestion Analysis Morning and afternoon peak hour LOS determined for CMS network Three time periods analyzed Existing TIP programmed projects (6 year horizon) Long range (20+ year horizon) Map Existing PM Peak Hour Congestion Level Peninsula South 2

3 Congestion Analysis Segment level of service Directional for freeways, bidirectional for surface streets LOS determined using Florida Q/LOS software (HCM) Traffic volumes and characteristics Roadway characteristics Default signal characteristics Separate bridge and tunnel analysis Travel times measured via probe vehicle Congestion Analysis Identified congested locations Created a congestion mitigation toolbox Recommended congestion management strategies for those locations without funded improvements Results incorporated into long range planning process Results also used in CMAQ and RSTP project selection 3

4 CMS Products The State of Transportation in Hampton Roads (CMS Part I) Summary of regional transportation trends from all modes Less technical, more graphical Designed for use both by decision makers as well as the public CMS Products CMS Part II Report Bridge and tunnel analysis Roadway congestion analysis Congestion mitigation strategies CMS Special Report Glossy report created for mass distribution Mailed to all members of HRPDC s distribution list (civic leagues, churches, libraries, public and private sector, etc.) 4

5 CMS - Regional Safety Study HRPDC conducted this study with the aim to improve safety and reduce congestion Compared crashes and crash rates on all freeway segments and nearly 500 intersections on the CMS network Identified hazardous locations and recommended improvements Difficulties arose since there is no single source for crash data in Virginia Localities have used the study to initiate safety grant applications and propose projects for inclusion in the TIP CMS - Travel Time Data Regional travel time collection Collected every 5 years for the CMS network via a GPS-equipped probe vehicle Only 1 run in each direction during AM & PM peak travel periods Used to determine regionwide travel trends, as well as travel trends to specific traffic generators Also collected for special studies 5

6 Future CMS Improvements? Congestion analysis with travel speeds rather than volume data Currently about 60 miles (50%) of the Hampton Roads Interstate system is instrumented by the Hampton Roads STC By the end of 2006, the entire regional Interstate system will be instrumented Data easily accessible via the Archived Data Management System (ADMS) Data quality severely limits the usefulness of this information Future CMS Improvements? Wireless location technology Demonstration project in Hampton Roads involving the Smart Travel Lab at UVa, FHWA and VDOT Cell phone pulses can hopefully be used to determine vehicle speeds anywhere on the roadway network 6
