STOP
SIGNS
Installation
of Stop Signs is governed by Warrants. The Manual of Uniform Traffic
Control Devices states that "….STOP signs should not
be used for speed control". They are included here as a possible
tool for discouraging cut-through traffic in residential areas.
They may also reduce collisions and severity of accidents (Source:
Traffic Calming: State of the Practice - ITE, 1999)
They tend
not to have much effect on mid-block speeds and can actually cause
an increase. They tend also to have low compliance.
Unwarranted stop signs are not recommended.
