What are the specific criteria for installing stop signs?
To determine whether or not a stop sign would be the best and most appropriate measure of traffic control, City of Warwick Department of Public Works (DPW) engineers work with Police Department Traffic Officers. They analyze the various characteristic of an intersection and any available crash data for that location. Some of the questions they ask themselves include:
Is this an intersection of a minor road with a main road where application of the normal right-of-way rule (e.g. yield to the right) is not apparent?
Is this an intersection where a street enters an arterial (major) street?
Is this an intersection where a combination of speed, restricted view and reported crash history indicates a need for control by the stop sign?
