Summary Information

Interstate 15 (I-15) is a north–south Interstate Highway that runs from San Diego, California, to the Canadian border. I-15 is a major corridor in San Diego that services commuting trips, regional traffic, and interstate and international commercial vehicles, and one of the pioneer sites in the USDOT's Integrated Corridor Management (ICM) Initiative. To estimate the benefits and costs associated with implementing ICM on the corridor, a study followed the USDOT Analysis, Modeling and Simulation (AMS) framework to assess the impacts of ICM strategies on mobility under high, medium, and low travel demand, daily operations, and freeway and arterial incidents. The assessed ICM strategies included pretrip 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.

The study estimated the capital, operating and maintenance (O&M) and annualized costs for the ICM strategies. Capital costs are up-front costs needed to procure and install ICM equipment. O&M costs are the continuing costs necessary to operate and maintain the deployed equipment including labor costs. Annualized costs are the average annual costs of deploying, operating, and maintaining ICM; annualized costs are especially useful when estimating long-term budgetary impacts of ICM projects. Annualized costs are determined from capital costs that have been amortized over the anticipated life of each piece of equipment.

Findings

  • A total 10-year life-cycle project cost of $12.0 million
  • An annualized cost of $1.42 million over the 10 year project life cycle
