Another win for San Diego’s integrated corridor management system
The SANDAG integrated corridor management system on Interstate 15 in San Diego has just picked up the California Transportation Foundation award for Operational Efficiency Program, for the second time in three years. This pioneering ICM project centers around a decision support system, for which TSS provides the Aimsun Online modelling tool.
Thanks in large part to the success of the ICM system, in 2015 USDOT added the SANDAG ICM network to the Dynamic Mobility Applications (DMA)-Active Transportation and Demand Management (ATDM Analysis, Modeling and Simulation (AMS) Testbed Project.
“Since last year we’ve made a lot of progress on the ATDM/DMA test bed” says Principal Consultant, Matthew Juckes. “With an analysis plan in place we are now developing the tools needed to model both the communications and functionality of connected vehicles within the platform, including Intelligent Network Flow Optimization and Cooperative Adaptive Cruise Control, with others on the short-term horizon.”
The system has been running in an automated stage since March 2014, taking automatic control of signals and ramps when recommended by the simulated evaluations. The most recent update is the introduction of 40 alternate route signs along the arterials to guide drivers through the surface streets from and to the highway during a diversion. This, in addition to newly enhanced local street detection coverage, continues to improve the quality of the system and its ability to improve mobility through the corridor.
