Aimsun real-time analytics for traffic management
First publishedin ITS World Congress
TSS-Transport Simulation Systems will be showcasing the Aimsun Online real-time decision support system for traffic management. The system is the analytical engine for high-profile traffic management projects such as the award-winning Interstate 15 Integrated Corridor Management System (ICMS) led by the San Diego Association of Governments (SANDAG) and, in France, the Grand Lyon pilot site for the Opticities project to optimise citizen mobility and freight management in urban environments. The Lyon real-time simulation management system offers standardisation for access to data and aims to merge the city’s current traffic management system, developed by SPIE, with a real-time predictive system for the inner city of Lyon.
At the core of both projects is the configuration and implementation of a decision support system (DSS) using Aimsun Online to evaluate and propose optimal traffic management actions. Aimsun Online uses live data feeds and simulations to dynamically forecast traffic conditions based on the current state of the network, allowing system managers to evaluate incident response or congestion management strategies. This means that rather than reacting to congestion as it happens, we can take pre-emptive steps to prevent system breakdown using devices such as traffic signals, ramp meters, and dynamic message signs.
