Traffic and Safety Division

All activities and programs led by the Traffic & Safety Division share one ultimate objective – to improve safety. The division is responsible for overseeing the research and programs that help improve transportation safety statewide. These responsibilities include safety improvement programs for work zones, school zones, traffic signals, and active transportation. Traffic & Safety personnel also supervise studies that determine the causes of crashes and other traffic hazards as well as discuss how these dangers can be minimized.

The programs administered by the Traffic & Safety Division are a service to the public. As you navigate through the various Traffic & Safety subtopics, you will see contact information listed. We value your input and encourage you to give us your comments or questions.
