The Traffic Engineering section is responsible for the traffic engineering and operations of the County roads. They work with the District Supervisor's office and with community and neighborhood groups to address neighborhood traffic issues such as speed and volume. They monitor the traffic on County roads to ensure safety and coordinate with the California Highway Patrol to provide enforcement and review accident history. They also work with the Design Engineering section to review and input on proposals that may impact the road network. Traffic signals, signing and striping plans are designed for developer and County projects.
