Traffic signals help keep traffic moving and reduce accidents. They can also pose a safety hazard when they fail to work properly. Traffic engineers determine whether an intersection needs signal controls by comparing existing conditions against nationally accepted minimum guidelines (warrants). Engineers consider factors such as collision history, current traffic levels, and speeds, sight distances, prevailing road use, and geometry. Installation When a request for a Street Lights Installation , it sets in motion a substantial chain of tasks. Traffic signal requests are evaluated on a case-by-case basis using a set of measurable criteria. These are compared to current engineering standards and principles, and a determination is made on the most appropriate safety improvement that can be undertaken at the location. During this process, the department must also determine whether or not a traffic signal would improve the flow of traffic at the intersection. This includes assessin
