On 22nd May 2014, the Interstate 15 Integrated Corridor Management Demonstrator Project in San Diego won the Operational Efficiency Program of the Year at the 25th Annual CTF Transportation Awards in California.
The San Diego ICM has been live since 2013 and deploys an innovative system designed to coordinate and optimise all available infrastructure, routes and modes.
The San Diego project team configured and integrated an online modelling package, delivering a pioneering Decision Support System (DSS) that can build on the state-of-the-art systems already in use on I-15. The DSS is a “smart” traffic management system that gives system managers comprehensive awareness of the performance of the entire corridor; it also allows them to take proactive steps to prevent system breakdown using enhanced controls across multi-jurisdictional devices such as traffic signals, ramp meters, and message signs.
At the heart of the DSS is Aimsun Live, which uses live traffic data feeds and simulations to dynamically forecast future corridor traffic conditions based on the current state of the network. Aimsun Live simulates and evaluates the impacts of different traffic management strategies and ranks them so operators can choose the best set of strategies to avoid congestion.
