The Transportation Authority of Marin (TAM) is designated as the congestion management agency for Marin County, and is tasked with preparing a Congestion Management Program to fulfill the state legislative requirements of Propositions 111 and 116, approved in June 1990.
TAM’s congestion management program monitors our local multi-modal transportation networks level of service on our roadways, bicycle and pedestrian facilities and transit services, and identifies improvements to the performance of these multi-modal systems.
The CMP consists of a system monitoring effort, performance measurement and capital improvement plan for these systems. As required by state legislation TAM maintains a travel demand model to forecast proposed changes to the transportation network.
Funding to conduct the Congestion Management Program is provided by CMA planning funds.
