Gateway Cities Traffic Signal Synchronization and Bus Speed Improvement Project

The Atlantic Blvd./I-710 Corridor is a County of Los Angeles project which will result in arterial infrastructure improvements on north-south and east-west arterials along I-710 freeway in the South-East Los Angeles County (Gateway Cities) Forum.

The Atlantic Blvd./I-710 project area consists of 642 intersections in the following 15 different jurisdictions, comprising 13 cities, the County and Caltrans.

  • Los Angeles County
  • Caltrans
  • Bell
  • Bell Gardens
  • Commerce
  • Compton
  • Cudahy
  • Huntington Park
  • Long Beach
  • Lynwood
  • Maywood
  • Paramount
  • Signal Hill
  • South Gate
  • Vernon

The objective of this project is to design, develop and deploy Advanced Traffic Management System(s) (ATMS) in the corridor so that the signals in the Project area can be synchronized across the jurisdictional boundaries. This project concentrates on the needs of the agencies in this corridor with respect to signal synchronization and recommends improvements to field infrastructure (including controllers, loops, detectors, and communications) and central traffic control systems to meet those needs.

When successfully completed, each of the agencies responsible for traffic signal operations in the Atlantic Blvd./I-710 Corridor will have full access to an ATMS that monitors and controls the traffic signals under their jurisdiction. Agencies will be able to synchronize their signals with neighboring agencies, and exchange traffic information in real-time. Agencies will also be able to exchange data with other agencies in the Gateway Cities region. This will allow the agencies to respond to recurrent and non-recurrent congestion in a coordinated fashion across the jurisdictional boundaries.
