1 I-95 / I-395 Integrated Corridor Management Hari Sripathi, P.E. Regional Operations Director

2 Purpose of ICM Initiative Address real time demand management in I-95/I- 395 corridor Identify tools to provide Information related to multimodal travel times and parking Address tools to enhance capacity such as shoulder travel lanes, other active traffic management schemes 2

3 Today's Corridors: Independent Systems Arterial Signal Systems Freeway Systems Rail Systems Bus Systems Parking Systems Efforts to date to reduce congestion have focused on optimization of individual systems Significant investments in ITS technologies Tremendous opportunities to integrate operations to manage total corridor capacity

4 The Commuter s View of ICM Destination choice Time of day choice Mode choice Route Choice Lane / Facility Choice providing travel choices 4

5 Participating Stakeholders Arlington County City of Alexandria Clean Air Partners Commuter Connections Dulles Area Transportation Association Fairfax County Department of Transportation City of Fredericksburg U.S. Department of Transportation Federal Transit Administration George Washington Regional Commission Loudoun County Metropolitan Washington Council of Governments (MWCOG) Northern Virginia Regional Commission (NVRC) Northern Virginia Transportation Commission (NVTC) Potomac and Rappahannock Transportation Regional Commission (PRTC) Prince William County U.S. Department of Defense U.S. Department of Transportation Federal Highway Administration Virginia Department of Rail and Public Transportation Virginia Department of Transportation Virginia Megaprojects (VDOT) Virginia Railway Express Washington Headquarters Services - DoD Washington Metropolitan Area Transit Authority (WMATA) Metropolitan Area Transportation Operations Coordination (MATOC) 5

6 Assets and Activities Freeway / Reversible HOV Parallel and connecting arterial network Express Lanes under development Commuter rail, express and local bus, Metro rail 40,000+ parking spaces (VDOT, transit) 1000 vanpools, 4000 carpools daily 6450 slugs daily (2009 VDOT) Real-time Ridesharing Pilot Est. 500 riders, 1000 drivers 6

11 Kiosks Pentagon Mark Center Ft. Belvoir Quantico Other Major Employers Major Shopping Malls Rest Areas

12 Arterials CANDIDATE SIGNAL GROUPS Transit signal priority along express bus routes Adaptive control along: Arterial alternate routes (incidents, congestion) Key routes between park-and-ride and I-95 12

13 Active Traffic Management and Shoulder Travel Lane 13

14 Adaptive Ramp Metering with HOV Bypass Upgrade 18 metered ramps along I-395 to vary rates based on real-time mainline flows Implement new ramp meters (some with HOV bypass lane) May require widening at some entrance ramps 14

15 Corridor Decision Support System Phase 1 (Performance Management) Collect, archive traffic flow and travel time/speed info for all VDOT routes in corridor Collect, archive operational info for transit services including travel time, average speed, schedule adherence, ridership / capacity, etc. Phase 2 (Modeling and Decision Support) Use macroscopic operations model to assess trends, compare information and guidance strategies, incentives to reduce traffic volume Provide recommended strategies and outputs directly into real-time traveler information and roadside displays; promote alternative modes, expedite travel during events, incident periods. 15
