Matthew Jukes and Sydnie White of TSS with Aimsun Online
TSS-Transport Simulation Systems is showcasing its Aimsun Online real-time decision support system for traffic management. One of the most high-profile traffic management projects to use Aimsun Online as its prediction engine is the award-winning Interstate 15 Integrated Corridor Management (ICM) project led by the San Diego Association of Governments (SANDAG). At the core of the project is the configuration and implementation of a Decision Support System (DSS) using Aimsun Online.
“The DSS gives system managers comprehensive awareness of the current and predicted performance of the entire corridor,” says Matthew Juckes, senior project manager at TSS. “Now managers can take proactive steps to prevent system breakdown using enhanced controls across devices such as traffic signals, ramp meters, and dynamic message signs.”
Taking it one step further, earlier this year SANDAG completed a ‘Coordinated Test Plan’ for the first ever ‘fully automated’ multi-modal corridor handling of a freeway incident. TSS says this is one of the first times in the US that a traffic management decision has been successfully made entirely based on automatically triggered real-time simulations of the entire multi-modal transportation network.
Another recent innovation to come from the ICM project is the free 511 San Diego mobile application which is available for iOs and Android. Funded by the US Department of Transportation, the app provides real-time predictions from Aimsun Online and system based advisories, letting users view predictive travel times on I-15; current traffic conditions; MTS bus routes, fares, arrival times; as well as real-time dynamic toll rates for the I-15 Express Lanes. Since its launch in May 2014 it has already had over 25,000 downloads.
