Among the many requests for signs and markings installations, the Transportation Operations Division receives numerous requests for the installation of stop signs. Each request is studied to determine whether or not installing stop sign is the appropriate safety measure.
We have found that most stop sign requests are generated by citizens with a genuine concern for traffic and pedestrian safety, who believe that the installation of stop signs would solve many traffic safety problems.
Unfortunately, the solution to some of these traffic safety problems is not always that simple. In some cases, the installation of stop signs may create a situation that is more of a problem than already exists. In these cases, other solutions may be more feasible.
When stop signs are installed where the need to control right-of-way is questionable, there would be an increase in traffic delay and congestion with little or no gain in safety. In fact, safety is sometimes reduced. The number of rear-end accidents sometimes increases and pedestrian accidents may increase because of a false sense of security provided by the stop sign. Excessive use of stop signs tends to frustrate and anger motorists, who may divert to less suitable streets. If the motorist consistently observes that the cross street traffic is light or non-existent, the stop sign's installation will be questioned by the motorist, and he/she will frequently roll through or run the stop sign, thus reducing the credibility of stop signs. In some cases, this can occur up to 25% of the time.
Although the physical installation of a stop sign is relatively inexpensive, studies have shown that there are "associated" costs involved which must also be considered:
There may be alternative solutions to the problem at your intersection. Trees or bushes can be trimmed or parking restrictions can be installed near the intersection to help increase visibility. It is the owner's responsibility to trim any privately-owned shrubbery obstructing any public signs. Police enforcement can improve safety. Installation of Interactive Radar Speed Display signs may prove to be an effective solution too.
Generally, the best ways to insure traffic safety are to educate motorists and pedestrians to be cautious at all times and to enforce traffic laws.
