Many citizens believe that installing a stop sign at an intersection will control speed along the roadway. However, unwarranted stop signs can actually create other problems both at the intersection and along the roadway. When unwarranted stop signs are used, drivers must stop more frequently. Thus, they tend to drive faster between intersections in order to save time. Unwarranted stop signs also encourage disobedience and the use of alternate, inadequate routes. Properly located stop signs can have various benefits. Aside from providing orderly traffic movement, they can reduce some types of accidents and allow minor street traffic to enter or cross a major roadway. Thus, before installing a warranted stop sign, an engineer should determine that the stop sign will improve the overall safety and/or operation of the intersection.
