When can a traffic signal be an asset instead of a liability to safety?
– Are there so many cars on both streets that signal controls are necessary to clear up the confusion or relieve the congestion? – Is the traffic on the main street so heavy that drivers on the side street will try to cross when it is unsafe? – Are there so many pedestrians trying to cross a busy main street that confusing, congested or hazardous conditions result? – Are there so many school children trying to cross the street at the same time that they need special controls for their protection? If so, is a traffic signal the best solution? – Are signals at this location going to help drivers maintain a uniform pace along the route without stopping unnecessarily? – Does the collision history indicate that signal controls will reduce the probability of collisions? – Do two arterials intersect at this location and will a signal help improve the flow of traffic? – Is there a combination of the above conditions which indicates that a signal will be an improvement rather than a detriment?
