Caltrans and transportation partners are taking a dynamic turn in transportation planning and operations with the creation of Corridor System Management Plans (CSMPs) for the most heavily congested transportation corridors – aimed at increasing transportation options, reducing congestion, and improving travel times.

A CSMP is a comprehensive, integrated management plan for increasing transportation options, decreasing congestion, and improving travel times in a transportation corridor. A CSMP includes all travel modes in a defined corridor – highways and freeways, parallel and connecting roadways, public transit (bus, bus rapid transit, light rail, intercity rail) and bikeways, along with intelligent transportation technologies, which include ramp metering, coordinated traffic signals, changeable message signs for traveler information, incident management, bus/carpool lanes and car/vanpool programs, and transit strategies.  CSMP success is based on the premise of managing a selected set of transportation components within a designated corridor as a system rather than as independent units. Each CSMP identifies current management strategies, existing travel conditions and mobility challenges, corridor performance management, planning management strategies, and capital improvements.

In District 3, six CSMPs have been developed.  The boundaries of each of these CSMPs are shown on the map below.  To view or print this map, please click here: D3 Map. To view an enlarged map of the transportation network for each CSMP corridor, please click on the highway in the map below.

Additional information about each CSMP corridor including final CSMPs can be found at Caltrans’ website at www.corridormobility.org or by contacting the CSMP Planning Manager listed below.
