​Overview

The Traffic Signal division studies, constructs, and repairs traffic signals, beacons, and flashers. We provide a safe, reliable, and efficient traffic signal system that provides access and mobility for various modes of transportation including vehicles, bicycles, and pedestrians. The Traffic Management Center and the Traffic Signal Shop provide a critical support to fulfill the goals of the Traffic Signal team. 

The Traffic Signal division submits funding applications to various external sources to explore feasibility of upgrading existing traffic signals to current national standards. The team has applied and secured funding for several million dollars on an yearly basis.


Traffic Signal Operations and Maintenance

The Operations Maintenance division designs, constructs, and repairs traffic control devices, such as traffic signals, school and pedestrian flashers, and street lights. The Congestion Management division conducts technical studies for traffic safety and installs traffic control devices.

I WOULD LIKE TO REPORT AN INTERSECTION IN FLASH/WITHOUT POWER- If an intersection has power but is not working correctly, the intersection might be in flash. If the intersection does not have power, the intersection may be dark. Intersections not in working colors should be reported by calling 311 and speaking directly with an agent. 

I WOULD LIKE TO REPORT A MISTIMED INTERSECTION- The Department of Transportation monitors timing at signalized intersections and adjusts the timing if needed. Intersections with timing issues should be reported by calling 311, visiting the 311 website or using the Dallas 311 mobile app.

I WOULD LIKE TO REQUEST A NEW TRAFFIC SIGNAL- The City of Dallas conducts studies to determine if an intersection should be built. Intersections that need to be considered for the installation of a traffic signal should be reported by calling 311, visiting the 311 website or using the Dallas 311 mobile app under the category "Traffic Signal- New".
