Traffic engineering is the foundation of our roads system in Marin County. We are responsible for the planning, geometric design and traffic operations of all roads and streets excluding state highways. We study traffic patterns and user habits in order to build and maintain a more efficient system of roadways which address the needs of all users of our streets and roads.
Our Traffic Engineers are experts in their field and when a problem arises, we study the situation; monitoring traffic statistics such as the number of accidents and traffic jams in the area, review speed data and roadway conditions. When the studies are finished, a decision is made as to the best way to resolve the problem. We try to offer solutions that maintain smooth and efficient traffic operations through the installation of traffic control devices such as signs, signals, road markings and speed limit changes. In this way, we offer our community the safest roads possible.
If it is an emergency, such as a traffic signal is dark, please call DC Electric at 866-523-8386 or for roadway obstructions such as fallen trees, see the Roads Division Page for the appropriate number.
