The installation of a Traffic Signal does not prevent crashes.

An evaluation (signal warrant analysis) is conducted to determine if the installation of a traffic signal is warranted. Consideration for installation of a traffic signal include, but are not limited to:

a. How much traffic is there?
b. Are the high levels of traffic consistent throughout the day?
c. Are there pedestrians? Is this a pedestrian route for school children?
d. Is the street wide? Are there high speeds? Is it a busy thoroughfare?
e. Will the installation of the signal improve the traffic flow or create grid-lock with other nearby signals?

Once this data is collected, they are compared to standards as set forth in the M.U.T.C.D. (Manual on Uniform Traffic Control Devices).

A properly placed signal can improve the safety and efficiency of traffic flow through an intersection. An unwarranted signal can be the source of danger and annoyance to all who use the intersection.
