Traffic Management

The Department of Public Works is responsible for maintaining our City’s traffic management system which includes traffic signals, pavement markings, signs, and more. Through the use of traffic studies, City staff is able to collect and analyze data to ensure the best traffic related treatments are implemented city wide to provide motorists and pedestrians an optimal traveling experience. Below you will find more detailed information. If there is a resource that would be helpful to you and it is not available, please let us know by contacting us at

The goal was to enhance traffic efficiency on our existing roadways using existing infrastructure. At the completion of this program, all traffic signals will continue to be evaluated for needed timing adjustments annually.
