The district conducts a traffic engineering study (if the city has not already provided this information) to determine if the location meets one of the signal justification warrants in the

Texas Manual on Uniform Traffic Control Devices (TMUTCD)

. (See Chapter 3 of this manual for a description of the traffic study.)

If the traffic study shows that the location meets at least one of the warrants for traffic signal installation (as described in the

TMUTCD

), the district then decides, based on engineering judgment, if the installation of a traffic signal would be in the best interest of the public. If the location does not meet at least one warrant, the request is denied.

If the traffic signal installation is deemed appropriate, the district traffic section then forwards its recommendation and a Traffic Signal Authorization Request form (described in Chapter 5 of this manual) to the district engineer for final approval and signature.

If the signal installation is approved, the district then determines who is responsible for the installation of the signal (based on the “Traffic Signal Policy” outlined in Chapter 1, Section 1, of this manual). If funding, installation, maintenance, or operation of the proposed signal will involve an entity other than TxDOT, the district must determine if a written agreement is required. Traffic signal agreements are covered in the

Negotiated Contracts Procedures Manual
