Intelligent Transportation System

Southern California Intelligent Transportation System (ITS) Regional Architecture is a Regional ITS Architecture for the SCAG region. The region includes the counties of Los Angeles, Orange, Ventura, Riverside, San Bernardino, and Imperial. The goal of the project is to document the ITS Architecture covering the Southern California Region. An ITS Architecture is a framework for ensuring institutional agreement and technical integration of technologies for the implementation of projects or groups of projects under an ITS strategy.

Regional ITS projects, or transportation projects, both highway and transit, with ITS elements, which want to be eligible for the use of Federal transportation funds, are required to be consistent with the Regional Architecture pursuant to 23 CFR 940.9 and 940.11. In addition, such projects must comply with system engineering requirements and applicable Federal standards that have been adopted for the implementation of ITS.

As part of the 2008 RTP process, SCAG updated its regional ITS architecture to incorporate security. This regional ITS architecture supplement incorporates security elements to the 2004 SCAG regional architecture at the regional and sub-regional levels.
