Traffic Signals

Requests for Traffic Signal Installation

Requests for installation of intersection controls may be submitted to the Engineering Department. A traffic study will be conducted to determine if an upgrade of traffic controls is warranted. The traffic study will include the measurement of traffic volumes into the intersection from all approaches, the analysis of the distribution of traffic throughout the day and gathering accident records for the intersection. If a traffic signal is determined to be justified, a four-way stop can be installed until funding for the traffic signal becomes available. (Traffic signals can cost more than $175,000 per intersection.)

About Traffic Signals

Intersection controls are intended to establish which vehicles have right-of-way, improve traffic flow and reduce intersection delays. Examples include yield signs, stop signs, traffic signals and turn prohibition signs. The Texas Manual on Uniform Traffic Control Devices (TMUTCD), a state-wide set of standards for traffic control devices, has very specific guidelines and criteria for the proper use and placement of intersection control.
