Description:

Signs are installed at a location to bring awareness to driving speeds or to enhance user safety. Warning signs can bring awareness to the presence of specific conditions such as a trail crossing, school zone, etc. Speed limit signs define the maximum enforceable speed of a given roadway. The speed limit is set based on geometric design and engineering and traffic surveys. A reduction to the speed limit would require an engineering and traffic survey and may need to be accompanied by changes in roadway geometry.

Advantages:

•    Heighten awareness of roadway speed limit or specific conditions.

•    Uses a standard traffic control device easily recognizable by motorists.

Disadvantages:

•    Does not physically restrict vehicles from speeding.

•    May become less effective over time.

•    Can lose effectiveness if used too often.

•    Cannot be used to reduce the existing speed limit without an engineering and traffic survey.

Suitable:

•    Residential and Collector Streets

•    Location where speeding occurs.

•    Along roadway curvature.

•    Roadways with high bike and pedestrian usage.

•    Schools zone.
