Traffic Light Synchronization Program (TLSP)


The Highway Safety, Traffic Reduction, Air Quality, and Port Security Bond Act of 2006, approved by the voters as Proposition 1B on November 7, 2006, included a $250 million program to fund traffic light synchronization projects and other technology-based improvements to improve safety, operations and the effective capacity of local streets and roads.  This Traffic Light Synchronization Program (TLSP) is funded from funds deposited in the Highway Safety, Rehabilitation, and Preservation Account.  The funds are available, upon appropriation by the Legislature, to the Department of Transportation (Department), as allocated by the California Transportation Commission (Commission).

In 2007, the Legislature enacted implementing legislation (Senate Bill 88) that designated the Commission as the administrative agency responsible for programming TLSP funds and the agency authorized to adopt guidelines for the program. 

SB 88 specified various administrative and reporting requirements for all Proposition 1B programs, and it directed that $150 million from the TLSP be allocated to the City of Los Angeles for upgrading and installing traffic signal synchronization within its jurisdiction.

The Department will develop a proposed program of projects for the TLSP on the basis of project applications prepared by regional agencies or recipient local agencies.  The Commission will adopt the program upon finding that it is consistent with the program intent, which is to improve safety, operations and the effective capacity of local streets and roads.

The Department will form a committee to conduct a review and objective evaluation of project applications, with representatives of staff from the Federal Highway Administration, the Department, and the Commission. The criteria to be used in the evaluation include a benefit-cost indicator, safety index, emission benefits, project delivery, and local funding partnership.

The Final Draft TLSP Guidelines provide eligibility, application, project selection and programming procedures.    

The TLSP Evaluation Number (TLSPEN) will be used as a benefit-cost indicator based on delay and fuel consumption savings.
