Connected Corridors

Connected Corridors (CC) was a collaborative program to research, develop, and test an Integrated Corridor Management (ICM) approach to managing transportation corridors in California. ICM views the corridor as a total system to be managed as an integrated and cohesive whole; it seeks to address the corridor’s overall transportation needs rather than the needs of particular elements or agencies alone. The Connected Corridors team developed a state of the art model and Decision Support System for use on a pilot project on Interstate 210. The pilot is now being spearheaded by Caltrans District 7 and will be deployed in Spring 2022. 

CC I-210 Pilot Vision

  • Pilot the 1st Connected Corridors ICM on I-210 in Los Angeles.
  • Bring together corridor stakeholders to create an environment for mutual cooperation.
  • Develop and deploy the I-210 Pilot as the most instrumented, modeled, and sophisticated corridor in the nation.
  • Focus on reducing non-recurrent congestion through traffic reroute opportunities.
  • Develop the system for expansion to all modes and recurrent congestion improvements.
  • Provides a foundation for future improvements and advances in transportation management. 

CC I-210 Pilot Accomplishments

Analysis, Modeling and Simulation

  • Data quality improved to 80-90% for the entire corridor
  • Real-time traffic-state estimation
  • Calibrated microsimulation model
  • Response plan library
  • Scorecard process for decision making
  • Solid foundation for ICM deployment 

ICM Core System

  • Standardized TMDD interfaces with each jurisdiction’s TMC (signals, ramps, sensing, signs), creating a library of multiple vendor products capable of communication with the Data Hub.
  • Data Hub scalable for any Caltrans district, providing storage and processing of data collected and incident management activities.
  • DSS for response plan development capable of operating in any corridor.
  • Corridor Management System providing full corridor situational awareness for all stakeholders.
  • Ability to deploy anywhere via AWS.

ICM Core System Capabilities

  • Real-time processing and storage of corridor data.
  • Traffic estimation for arterials and freeway.
  • Traffic prediction for response plan evaluation.
  • Response plan development and incident lifecycle management.
  • Repeatable solution for other regions, corridors, CT districts via AWS and deployment automation.
  • Configurable system to address local and regional differences.
  • Changeable workflows to manage pipelines and incident lifecycle.
  • Scalable solution for virtually any size implementation.
