Stop Signs

Stop Sign The purpose of stop signs is generally misunderstood by the public. The purpose of the stop sign is provide safe and orderly operation at an intersection that is otherwise compromised without the signs.

The City receives many citizen requests for installing stop signs for a number of different reasons. The most common inquiry is to install a stop sign to slow traffic through their neighborhood. However, research shows that other measures are often more effective than adding “nuisance” stop signs. Information on some of these other measures can be found on the following link:
Studies have also shown that adding unwarranted stop signs can actually increase speeds as drivers try to make up for perceived “lost time”.

Some of the other reasons for requests include crash reduction, intersection visibility concerns, and travel time delay reduction. These requests are more fitting with the intended purpose of stop signs and are investigated by the City on a case-by-case basis.
Installation Policies
The Federal Highway Administration publishes the 
Manual on Uniform Traffic Control Devices (MUTCD).This publication dictates all aspects of signing and striping within public roadways. The MUTCD dictates the size, shape, and color for traffic signs, signals, and other traffic control devices.

Included within the MUTCD are guidelines for where signs and signals are installed that create uniformity from city to city and state to state. The City of Billings is required by State law to comply with the guidelines contained within the MUTCD. A stop sign will only be installed after careful engineering evaluation complying with the MUTCD guidelines of the existing conditions indicates that the installation is appropriate.
The guidelines outlined for stop sign installations are dependent on a number of factors.  When a citizen request is made, each of these factors are researched and analyzed to determine if a stop sign is justified for installation.  Some of these factors are listed below:
  • Volume of traffic on both intersecting roadways
  • Recorded crash history
  • Sight distance from one street to the other
  • Prevailing traffic speeds
  • Roadway classification (i.e. hierarchy of roadway network)
  • Temporary installation prior to signal installation

This process will also look to optimize the intersection without the use of signs.  Our experience has shown that improving the intersection sight distance by prohibiting parking near the intersection or trimming trees and shrubs is often more effective in reducing traffic accidents.  This often eliminates the need to install more restrictive intersection controls.  The overuse of stops signs can reduce their effectiveness.
