Integrated Corridor Management: Analysis, Modeling, and Simulation for the I-15 Corridor in San Diego, California
A 2010 study used the USDOT Analysis, Modeling and Simulation (AMS) framework to evaluate the impact of implementing Integrated Corridor Management (ICM) on the Interstate-15 Corridor in San Diego, California. Serving as one of the pioneer sites in the ICM initiative, the I-15 Corridor consists of an 8 to 10 lane freeway that services commuting trips, regional traffic in off-peak hours, and interstate commercial traffic. The AMS study assessed the impacts of ICM on the I-15 Corridor under high, medium, to low travel demand, and during daily operations and freeway and arterial incidents. The study tested the following ICM strategies: pre-trip and en-route traveler information, mode shift to transit, freeway ramp metering, signal coordination on arterials with freeway ramp metering, physical bus priority, and congestion pricing on managed lanes.
