2 Integrated Corridor Management involves viewing corridor assets such as freeways, arterials, and transit through a common lens. Source: Federal Highway Administration PennDOT s Transform 76 ICM Initiative I-76 (Schuylkill Expressway) Expressway

3 Managing Freeway Corridors State of the Practice - State DOTs manage freeway corridors to: Manage Congestion Promote Quick Incident Clearance Provide Actionable Traveler Information Leading states are working to promote multi-modal operations Improve Roadway Safety Reduce Secondary Accidents Provide Information about Severe Weather 3

4 Managing Arterial Corridors State of the Practice challenges on arterial corridors: Most State DOTs employ aggressive signal optimization programs on the signals they operate and maintain SPaT Challenge making progress - 38 active sites However, Signals often operated by multiple entities on a single corridor (institutional barriers) Lack of region-wide (MPO Level) situational awareness Many proprietary signal systems Municipality controlled work zones and special events 4

5 Crowd Sourced Data Does this impact ICM? In severely congested areas, crowd-sourced data routing vehicles off the freeway onto arterials L.A.

7 PennDOT s Transform 76 In addition to building strong regional partnerships and enhancing traveler information programs, PennDOT will employ technology and innovative strategies used and proven elsewhere in the U.S. and the world: Variable Speed Limit* Queue Detection/Warning* Dynamic Junction Control Flexible Lane Use Ramp Metering Multi-modal Improvements Coordinated Traffic Signals* *ATMS System Engineering/software development underway 7

8 Statewide Unified Traffic Signal Command & Control Sustainable approach to managing and improving Traffic Signal Maintenance and Operations Why is this needed? Interoperability is critical to maximizing existing capacity PennDOT and Municipal situational awareness and seamless operations Connected and Automated Vehicle applications Integrated Corridor Management (ICM) Reduce duplicate software Reduction of maintenance support costs Consistency for TMC operators for more timely and efficient operation of traffic signal systems 8

9 Goals Advancing Operations Safety Mobility Effective Management Future Ready Local Control Controller Detection Corridor Control Communications Corridor Progression Adaptive Systems Central Management Central Server Database Monitor performance Situational awareness Advanced Applications Interoperability Connected & Automated Vehicle Applications 9 Performance based specification; multiple vendors One system; One vendor Innovative technology

10 Coordinated Traffic Signals PennDOT has been partnering with Q-Free since 2013 on a statewide NextGen ATMS Platform PennDOT has identified 160 traffic signals in Montgomery County and the City of Philadelphia along adjacent arterials PennDOT plans to take O & M responsibilities with the intention of modernizing the signal equipment and communications to actively control signal operations from a centralized location, building upon the Regional Integrated Multimodal (RIMIS) project. Modern signals infrastructure will be a crucial element as connected vehicle technology is incorporated into automobiles. 10

14 Enhancing Traffic Incident Management (TIM) TIM is an integral part of any ICM deployment Quick diversion of traffic to clear the way for public safety and emergency response personnel and vehicles to more quickly approach an incident while minimizing the potential for secondary incidents Enhanced traveler information, allowing motorists to understand incident impacts and make alternate route or modal choices Establishment of a central platform for collaboration among TIM partners 14

15 Traffic Incident Management (TIM) TIM diversion plans are stored as REST service to compliment the business rules response. Benefits: Flexibility of business rules engine (new devices, new DMS policies, etc.) Layered TIM plan elements Traffic Signal Plans (can be automated via Intelight MaxView integration) Detour Routes (overlay on response map / included in DMS response) 15

16 Summary Ability to invoke corridor level traffic response plans with real time signal timing modifications. Architecture is being designed to be scalable and could be a model for future initiatives in other highly congested corridors not a one off Traffic signals can be controlled from TMC during incidents and major events TMC will have signal status integrated into ATMS platform 16
