All-way stop control (a stop sign on all intersection approaches) may be needed at intersections where crashes attributed to the current intersection traffic control configuration occur at an unacceptable rate, and where traffic volumes do not warrant traffic signal control. Traffic professionals evaluate the number of vehicles entering the intersection from all approaches, as well as accident frequency and types, speed of vehicles entering the intersection, intersection sight visibility, and the number of pedestrians and bicyclists using the intersection. If conditions meet specific requirements necessary for the installation of all-way stop control, the City will review and consider installing the stop signs as well as the necessary pavement markings and advance warning devices, as applicable.
Standards for Installation of All-Way Stop Control
Traffic engineering principles, guidance, and requirements (MUTCD, NACTO, AASHTO, ITE, FHWA, et. al) will be considered when evaluating the need for all-way stop control at an intersection.
A separate government or private entity may own or maintain one or more of the streets at the intersection where a request for all-way stop control has been made. This may require the other government or entity to provide review and approval of the request.
Process for Requesting All-Way Stop Control at an Intersection
The process to request an evaluation for all-way stop control at an intersection is as follows:
Department of Traffic and Transportation is contacted with an all-way stop request location, preferably by the neighborhood president, if one exists
Department of Traffic and Transportation provides the study area
A request for all-way stop control at an intersection is submitted to the Department of Traffic and Transportation in writing (email or letter). Included with this request is a petition (click HERE for petition form) showing support for all-way stop control of 75% of the property owners and renters within the study area identified by the Department of Traffic and Transportation. Only one signature per address will be counted. The petition should include:
Name of property owner/renter
Residency type (renter or homeowner)
Once the written request and petition in support is received, the Department of Traffic and Transportation will study the installation of all-way stop control at the requested location using traffic engineering standards. In addition, other government or private entities which own or maintain impacted streets will be notified of the study, and their approval may be needed in addition to the Department of Traffic and Transportation. Approval is also required from emergency responders (police, fire department, EMS) as the addition of a stop sign could impact their response time.
Once the study has been completed and reviewed by Department of Traffic and Transportation staff, the requestor will be notified of the results.
