The City of Durham Department of Transportation installs and maintains traffic control devices, including stop signs, in accordance with the Manual on Uniform Traffic Control Devices (MUTCD). The MUTCD is approved by the federal highway administrator as the national standard for all traffic control devices. Stop signs are installed based on an in-depth engineering study, as outlined in the MUTCD. The City’s Director of Transportation approves the installation of stop signs when warranted.
The NCDOT must also approve stop sign installations on state system streets. The Transportation Department routinely conducts investigations as part of an ongoing Accident Reduction Program. In addition, resident concerns may initiate an engineering warrants based study for stop sign installations.
