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

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
Active Traffic Management and Shoulder Travel Lane 13
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
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
