Parsons has been contracted by Caltrans District 7 to develop a decision support system using artificial intelligence that will help relieve hot spot congestion areas and improve travel reliability along the I-405 Sepulveda Pass corridor in Los Angeles, CA. The I-405 Sepulveda Pass corridor is the most congested highway segment in the United States.

To help relieve congestion and mitigate impacts caused by traffic events, Parsons will work with Caltrans District 7 Traffic Operations and Los Angeles City Department of Transportation (LADOT) to explore utilization of corridor management concepts and implement the decision support system along the I­‑405 corridor from I‑10 to SR 101, which will coordinate freeways with local arterials and improve mobility for commuters.
“Integrating this artificial intelligence solution with Caltrans’ existing advanced transportation management system will allow systematic freeway traffic responses that are in sync with arterial traffic signal operations,” stated Donald Graul, Connected Communities Market Leader. “The decision support system helps improve mobility without building additional infrastructure.”
The decision support system is a logic-driven, decision-making application that uses structured rules combined with incident and real-time congestion data to drive operational traffic strategies that mitigate and minimize impacts caused by events. Caltrans’ advanced transportation management system is a computer system application that was designed to monitor and manage all aspects of the freeway system in California’s Los Angeles and Ventura counties.
