Neighborhood Traffic Safety

Traffic Safety Committee

The City of Dublin receives periodic requests for a review of potential traffic safety issues around the City. The City’s Traffic Safety Committee, comprised of representatives from Dublin Police Services’ traffic unit, Public Works’ transportation staff, and City maintenance staff, meets once a month to discuss these issues and recommend appropriate actions. Please contact the Public Works Department if you have a traffic safety concern you would like to have brought to the attention of the Traffic Safety Committee. Some common inquiries that the City receives are for:

Speed Bumps

The City of Dublin does not install speed bumps as a means of traffic calming on publicly maintained streets. There are various negative impacts associated with the installation of speed bumps. Including:

Noise pollution due to vehicle acceleration and deceleration
Emergency vehicle response times
Unintended diversion of traffic to alternate routes.
Increased speeding due to some drivers accelerating more between speed bumps in order to “make up for lost time.”

Alternative measures for traffic calming will be considered if speed is observed as an issue after a field investigation.

Stop Signs

Stop signs are installed only after an engineering study is completed and the location is deemed to meet the criteria set forth in the California Manual of Uniform Traffic Control Devices (CA MUTCD). These criteria include traffic and pedestrian volumes, collision history, or abnormal conditions that would justify the installation of a stop sign.

Signs & Pavement Markings

New sign and pavement markings requests will be considered after an investigation by City staff. Signs and pavement markings must comply with the standards set forth in the CA MUTCD. If deemed appropriate after an investigation, action will be taken by the City’s maintenance staff. Depending on the scope of the request, it may take anywhere from 2-8 weeks for an action to be completed.

Speed Limits

Speed limits are set based on the criteria provided in the California Vehicle Code (CVC). On non-residential streets, an Engineering and Traffic Survey is required to be completed, which reports the 85th percentile speed of the roadway, or the speed in which 85% of the drivers travel under; collision history; and conditions not readily apparent. The posted speed limit is then set by rounding the 85th percentile speed to the nearest 5 mph. An additional 5 mph reduction in the posted speed limit is allowed in certain situations.

On residential streets, the prima facie speed limit of 25 mph applies. This is the minimum allowable speed limit in a residential zone.
