Transportation / Divisions / Traffic Division

The Traffic Division is responsible for providing efficient and safe flow of vehicular, pedestrian, and bicycle traffic. Activities include the maintenance of signs, markings and traffic signals as well as the management of traffic. This management will be coordinated through a new Traffic Management Center (TMS), currently under development. Traffic Management activities will include maintenance of traffic, parking restrictions, events management, traffic signal coordination, truck routing, development review, safety studies, red light enforcement and community traffic calming.

Traffic Engineering

The Traffic Engineering section is responsible for making sure that the roadways are available for the safe efficient conveyance of vehicle, pedestrian and bicycle traffic. Traffic management plans are developed and implemented for parades, sports events, fireworks etc. Requests for lane or street closures for construction or events are reviewed and the field set-ups are inspected. Set-ups are installed to facilitate road work performance.

This section generates plans and work orders for installations of signs and pavement markings. All new development plans are reviewed to ensure that safe and efficient movement of traffic and the plans are prepared for any needed traffic improvements.

Truck restrictions are established and modified as needed to strike a balance between community impacts and the needs of businesses. Permits and routes for oversized loads are issued and escorts are provided to coordinate with police.

Traffic engineering personnel work with community groups to address concerns and to develop traffic calming measures where appropriate. Traffic engineering personnel also work with the MTA to improve the Regional Transit System.

Signal Engineering

The Signal Engineering Section is responsible for the design of new and existing traffic signals. Specific projects include:

  • Development of a state-of-the art Traffic Management Control Center (TMC)
  • Replacement of the City's 1300 Traffic Signal Controllers
  • Replacement of the 40,000 plus traffic signal bulbs with LED's (Light Emitting Diode)
  • Signal timing contract to retime signals in the Central Business District and along selected gateways
  • Installation of traffic monitoring cameras

  • Management of the Red Light Camera Program, which has resulted in dramatic reductions and accidents citywide especially those caused by red light running.
