How Stop Sign locations are determined?


Douglas County follows general guidelines in the design of  signs in order to conform to basic standards. Many of these guidelines are mentioned in various sections of the Manual on Uniform Traffic Control Devices (MUTCD).


Manual on Uniform Traffic Control Devices (MUTCD)


Numerous studies and project evaluations have repeatedly demonstrated the cost effectiveness of pavement markings as a means of enhancing both traffic safety and mobility. Pavement markings separate travel lanes and help delineate travel paths and the edge of the roadway. They may stand alone to indicate certain traffic rules and regulations or may be used to supplement regulations or warnings given by other traffic control devices.

Signs and Markings (FAQs)

Why can’t we have a stop sign in our neighborhood to reduce accidents?

Installing an unnecessary stop sign as a “nuisance” or “speed breaker” may actually increase the number of accidents in the area. The unwarranted signs breed disrespect by motorists who tend to ignore the signs or slow down without stopping. Impatient drivers view the additional delay as “lost time” to be made up by driving faster between signs.

What are traffic control zones and how should I react?

Whenever construction is in progress on or near the roadway, drivers face rapidly changing traffic conditions. These changes can be hazardous for drivers, workers and pedestrians unless protective measures are taken. Traffic control zones are divided into several areas to increase safety for both workers and motorists. The areas include: Advance Warning Area – tells motorist what to expect, Transition Area – moves traffic out of its normal area, Buffer Area – provides protection for traffic and workers, Work Area and Termination Area – lets traffic resume normal driving. When traveling through these control areas, always be alert for workers and decrease your speed to increase safety.
