Comprehensive Transportation Projects

Intelligent Transportation Systems

The Regional Intermodal Transportation Management Systems (TMS) Network includes subsystems to better manage the region's freeways, roads, transit, incidents and emergency response, special events, commercial vehicle operations, and traveler information.

Projects being conducted as part of the Intelligent Transportation System (ITS) program include the Southern California ITS Priority Corridor Program and Regional Traveler Information System.

Southern California Intelligent Transportation System Priority Corridor Program
A multiregional effort is underway to interconnect transportation management centers in Southern California.

San Diego County and six other Southern California counties have collectively been designated by Congress as a national ITS demonstration corridor.

SANDAG administers the demonstration project on behalf of 22 agencies that make up this important multiregional effort to build a Southern California Transportation Systems Management (TSM) Network.

The Corridor TSM Network project provides the essential communications and software services necessary to link local and regional agency systems so they can work together cooperatively. This Network interconnects the transportation management centers of southern California (Cities, Counties, and transportation agencies in the SANDAG and SCAG regions) to enable the agencies to cooperatively improve the efficiency and performance of the overall transportation system.

ITS enables local agencies to cooperatively manage the overall performance of both the local and regional transportation systems.

Regional Traveler Information System
SANDAG assists local agencies to administer the implementation and installation of the region's traveler information system in cooperation with private industry partners. The first phase of the project will include delivery of real-time travel information for freeways, arterial streets, transit, and commercial vehicles using traditional media sources (e.g., television, telephone, Internet). Dissemination of real-time information by new technologies (e.g., cell phone, cellular Internet, hand held computers, and in-vehicle navigation devices) will follow in the second phase.
