The City installs stop signs at an intersection only after a careful engineering evaluation of the existing conditions show the installation is appropriate. Some intersections do not need stop signs to improve safety. Overuse of stop signs reduces their effectiveness.
Drivers tend to ignore unwarranted stop signs.
Stop signs are not effective in reducing travel speed. Drivers try to make up for the delay by speeding up between stop controlled intersections. The number of broadside accidents is reduced. Acceleration and deceleration increases noise and air pollution near the signs. The frequency of rear-end accidents is likely to increase.
