Why traffic signs are not used for speed control

 

August 20, 2004

 

One of the most common requests the Parish receives is for the installation of stop signs to slow speeders in neighborhoods.

 

 

It seem like an obvious, inexpensive way to reduce vehicle speeds.  However, what seems to be a perfect solution actually causes other problems.

When stop signs are used as "nuisances" or "speed breakers," there is a high incidence of drivers intentionally ignoring the sign.  When vehicles do stop, the speed reduction is effective only in the immediate area of the sign, since a large percentage of motorists then increase their speed to make up for lost time.  This results in increased mid-block speeding.

For these reasons, we do not use stop signs as speed control devices.  Instead, they are used to improve safety at intersections where traffic volumes or accidents require them.

"Children at Play" signs

A frequent request to the Parish is for "Children at Play" signs.  Some parents believe that the safety of their children playing in or near the street can be enhanced through the installation of "Slow Children" or "Children at Play" signs.

Traffic studies have shown that such signs do not cause drivers to slow and do not reduce pedestrian accidents.  In fact, placement of these signs can increase the potential for accidents by giving children and parents a false sense of security.

For these reasons, the Calcasieu Parish Police Jury does not install these types of signs, and instead, encourages parents and/or guardians to find alternative play areas for children, such as a backyard or local park.
