Frequently Asked Questions

Why is a CSMP important?

Californians recognized the critical need to reduce congestion on our vital travel corridors when they approved new transportation
funding through the Highway Safety, Traffic Reduction, Air Quality and Port Security Bond Act, known as Proposition 1B, in November 2006. Along with new funding came the responsibility to ensure that money is used efficiently and produces measurable results. CSMPs integrate capital improvements, traffic and transit management strategies and planning toward one common goal: keep people and goods moving safely and efficiently through a corridor. A corridor must have a CSMP to be eligible to receive funds from the Proposition 1B-funded Corridor Mobility Improvement Account and the Highway 99 Bond Programs.

How does a CSMP relate to other plans?

Caltrans is working together with cities, counties, regional transportation planning agencies, transit operators, bicycle groups, and
others to develop CSMPs and integrate the recommendations into all relevant transportation planning processes. A CSMP does not replace regional or local transportation plans but is intended to provide a strategy for integration and coordination, so that agencies can implement actions for more efficient corridor operations.

Who approves and implements a CSMP?

CSMPs are not officially approved by any agency, but are presented to the California Transportation Commission for information and provided to regional and local agencies for integration of the recommendations into their own plans and funding programs. It will be the responsibility of Caltrans, the regional agencies, and local cities and counties to implement the recommendations in each CSMP.

When will the CSMPs be completed?

The goal is to finish all the forty five first-generation CSMPs statewide by October 2010. The CSMPs will be continually updated thereafter. As of June 2009, about half of these CSMPs are complete and others are in progress. All the completed documents and the works in progress can be downloaded from this website.

How will a CSMP affect my commute?

Because the focus of a CSMP is to use proven methods to streamline the operations of a corridor and monitor the effectiveness of these methods, over time commuters should notice real improvements in travel times as well as an increase in travel mode choices (such as public transit, carpool/bus lanes, and bicycling).
