Integrated Corridor Management (ICM)

2. What is ICM? • ICM is a promising tool in the congestion management toolbox that combines advanced technologies and innovative practices. • ICM is the proactive, joint, multimodal management of transportation infrastructure assets along a corridor by transportation system operators and managers. • ICM seeks to optimize the use of existing infrastructure assets, making transportation investments go farther. • With ICM, the corridor is managed as a system—rather than the more traditional approach of managing individual assets.

3. Example ICM Corridor Local Jurisdiction 1 — Traffic Signal System Regional Rail Agency — Train Management System State DOT — Freeway Management System Bus Company — AVL System Local Jurisdiction 2 — Traffic Signal System

4. ICM System Freeway Systems Arterial Signal Systems Rail Systems Bus Systems An ICMS is the set of procedures, processes, and information systems that support transportation system managers in making coordinated decisions involving the optimal performance of all transportation networks in a corridor.

5. ICMS Context “ICM is about management of a corridor. Management implies more than monitoring. Management implies planning for, and responding to what is happening.” Operational Objectives – Provide the Tools To: • Optimize performance at a corridor level • Improve utilization of existing infrastructure • Reduce travel delays • Achieve load balancing across the networks • Facilitate mode shifts • Facilitate route shifts • Facilitate departure/arrival shifts • Respond to events with coordinated multi-agency actions

11. Data Needs Analysis ICMS introduces needs that were not present when we were only dealing with one network at a time. • Data collection needs time stamps so data from different sources can be aligned • Data granularity is different for ICMS (we need finer spatial and temporal detail) • Data latencies that were acceptable for reporting will not work for operational modeling and control • Decisions about how to respond to current situations should not be based on data that is days or weeks old. • Observational data needs to be collected often enough to represent the current situation. • Observational data needs to be available quick enough to facilitate a useful response • Challenges: Data sharing limitations: proprietary data, agency policies, incompatible data systems

12. ICM Data Requirements • Transit Networks - We need data that represents the current situation • Vehicle location and speed every 30-120 seconds • Vehicle passenger count every pull-out • Arterial Networks – We need data that represents what is happening at the lane level • Vehicle volumes, by approach lane, collected every 1-5 seconds & reported every 30-300 seconds • Signal phase data, by approach lane, collected every 1-5 seconds & reported every 30-300 seconds • Link volumes and average speeds every 30-300 seconds

13. Corridor Performance Measures • Travel time • Travel delay time and predictability • Incident duration and frequency • Fuel consumption and pollution reduction • Corridor capacity utilization (vehicle & traveler throughput)
