Integrated Corridor Management (ICM) ITS America Annual Meeting 2010 Session SS24 Integrated Corridor Management (ICM) Steve Mortensen Senior ITS Engineer Federal Transit Administration May 4, 2010

What is ICM? The integrated management of freeway, arterial, transit, and parking systems within a corridor Management of the corridor as a system, rather than the more traditional approach of managing individual assets ICM is the integrated management of freeway, arterial, transit, and parking systems within a corridor using ITS technologies and innovative practices or strategies It includes technical, operational (mitigate recurring and nonrecurring congestion, incident management, event management, maintenance, work zones), and institutional (Federal, state, city, transit agencies, emergency management organizations) integration Key ICM Areas: Load Balancing Demand Management Incident Management During: Recurring congestion Incidents Planned events (e.g., construction) Special events (e.g., concert, sporting events) Adverse weather

Broad ICM Strategies Increase multi-agency collaboration and coordination for overall corridor management Coordinate incident management Coordinate operations for planned and special events Optimize corridor mobility by promoting shifts in departure time, mode, and routes Manage demand

Supporting ITS Technologies HOT lanes / congestion pricing Transit signal priority Multimodal traveler information / Actionable traveler information Real-time traffic signal coordination, timing, and control Adaptive ramp metering Integrated electronic payment HOV strategies (change number of occupants, open to SOV during incidents) Congestion pricing with transit service, such as BRT Transit signal priority Multimodal traveler information (pre-trip and en-route) via 511, PDAs, the Internet, and the transportation infrastructure / Actionable traveler information Next transit vehicle arrival times Real-time parking availability information for park-and-ride facilities Freeway, arterial, and transit travel times Alternate route and mode information Real-time traffic signal coordination, timing, and control Adaptive ramp metering System-wide Coordinated signal and ramp metering operations Integrated electronic payment (e.g., fare incentives/changes)

ICM Initiative Goals Demonstrate and evaluate strategies and ITS technologies that help transportation operators efficiently and proactively manage corridors Provide the necessary tools, knowledge, and guidance, for ICM Phase 1: Foundational Research Phase 2: Corridor Tools, Strategies, and Integration Develop an ICM AMS methodology to enable localities to assess which ICM strategies provide the biggest benefit locally Apply and test the AMS methodology in a test corridor (35-mile segment of I-880 in the San Francisco Bay Area) Investigate and address ICM issues and needs, such as arterial and transit surveillance and detection data gaps, decision support systems, ITS standards, and corridor performance measures Phase 3: Corridor Site Development, Analysis, and Demonstration Stage 1: Pioneer Sites (August 2006 – March 2008) Eight sites were awarded funding in Fall 2006 to each develop a concept of operations document and requirements document. See next slide for list of Pioneer Sites. Stage 2: Modeling Sites (Summer 2008 – Summer 2010) Three of the Pioneer Sites were selected in Summer 2008 to analyze, model, and simulate ICM in their corridors. These include Dallas, Minneapolis, and San Diego (see slides 9-11). Stage 3: Demonstration Sites Dallas and San Diego were selected in Fall 2009 to demonstrate ICM in their corridors. This stage will consist of 18 months for design and development, and 18 months for operations and evaluation. Phase 4: KTT Outreach and Knowledge and Technology Transfer Develop outreach materials to raise awareness about ICM Develop a range of ICM KTT resources that equip corridor transportation practitioners to implement ICM

Eight USDOT ICM Pioneer Sites 3 Stages for the Pioneer Sites: Stage 1 – Concept of Operations, Sample Data, and Requirements Stage 2 – Analysis, Modeling, and Simulation Stage 3 – Demonstration and Evaluation Seattle Minneapolis Montgomery County Oakland San Diego Key Messages: The USDOT considers these eight Pioneer Sites to be critical partners in the development, deployment and evaluation of ICM concepts. These Pioneer Sites will develop multimodal ICM strategies that apply new institutional and operational approaches and advanced technologies to existing infrastructure to manage congestion and empower travelers. All eight of the Pioneer Sites are recognized leaders in the area of congestion management. The Pioneer Sites’ efforts will directly contribute to more efficient, reliable and safer corridors for the future Their corridors possess configurations and characteristics that the USDOT believes represent many other corridors across the nation.

ICM AMS Methodology: Provides Multi-level Analysis Regional patterns and mode shift; Transit analysis capability Traveler information, HOT lanes, congestion pricing and regional diversion patterns ICM AMS Methodology: Combine capabilities of and integrated the following existing analysis tools: Macroscopic travel demand models (e.g., Tranplan, TransCAD ) Effective in analyzing regional travel patterns and mode shift. Macroscopic models estimate travel demand based on projections of household and employment characteristics and predict travel preferences in activity location, time-of-day, mode, and route choice. Mesoscopic simulation models (e.g., Dynasmart-P) Effective in analyzing traveler information, tolling, HOT lanes, and congestion pricing, and regional diversion patterns Microscopic simulation models (e.g., VISSIM, CORSIM, Paramics) Effective in analyzing traffic control strategies such as ramp metering and arterial traffic signal coordination Test Corridor: Applied and tested the AMS methodology in a test corridor (35-mile segment of I-880 in the San Francisco Bay Area) Modeled the following ICM strategies: Highway Traveler Information: Pre-trip and en-route traveler information at 20% market penetration + variable message signs; drivers pick different routes, shift modes, or delay trip Transit Traveler Information: Impact of pre-trip and en-route incident information on mode shift; information on incident conditions, expected delays, transit options, scheduled transit travel times, parking availability HOT Lane: Conversion of existing HOV lane to HOT lane Ramp Metering: Local adaptive ramp metering (not corridor-adaptive ramp metering) Arterial Signal Coordination: 157 traffic signals were optimized for medium demand/no incident Combination: The above five ICM strategies combined Benefits: ICM 10-year benefit of approximately $300 million Different ICM strategies are more effective under different operational conditions. Results will vary from site to site. Mode Shift: In the presence of a major incident (2 freeway lanes blocked for 45 minutes), 1 – 4 percent of travelers affected by the incident shifted to transit when presented with transit traveler information. Could be improved with implementation of additional transit ICM strategies (e.g., fare incentives, transit service improvements such as BRT & TSP). For the test corridor, the HOT lanes and highway traveler information were consistently the most effective ICM investments in terms of both the benefit/cost ratio and net annual benefits (annual benefits minus annual costs) Traffic control strategies such as ramp metering and arterial traffic signal control 10 10 10 10

AMS Pioneer Sites Dallas (US-75) Minneapolis (I-394) San Diego (I-15) These sites were selected in Summer 2008 as AMS Pioneer Sites to model (a subset of) their proposed ICM strategies and ICM systems. Corridor Level Performance Measures: Travel time Travel delay time and predictability Incident duration and frequency Fuel consumption and pollution reduction Corridor capacity utilization (vehicle & traveler throughput)

AMS Pioneer Sites - Strategies ICM Strategy Minn. Dallas SD Traveler Information Earlier dissemination and information sharing between agencies  Comparative travel times (mode and route) Parking availability at park and ride lots ABC garage display Freeway traveler information (pre-trip and en-route) Arterial traveler information (pre-trip and en-route) Transit traveler information (pre-trip and en-route) Traffic Management Reduced incident times Incident signal retiming plans for arterials or frontage roads Retime ramp meters for incidents or congestion Coordinated signal and ramp meter operation Systemwide coordinated ramp metering Minneapolis plans to model earlier dissemination of freeway, arterial, and transit information, both pre trip and en-route (that is why the freeway, arterial, and transit traveler information rows are blank for Minneapolis). Minneapolis was going to model the provision of traveler information at downtown parking garages (ABC garage display) but this strategy is only useful for the PM peak. Minneapolis is only going to model the AM peak period. That is why this row is blank. All other completely blank rows were strategies considered for modeling at one time but were dropped after later consideration (often due to limited modeling funds).
