Traffic Calming

The City of Beaverton is committed to maintaining and improving the livability and safety of its residential neighborhoods. The goals and policies of the City’s Transportation System Plan and Comprehensive Plan provide the policy foundation for the program; specific traffic calming goals and policies provide for implementation. The procedures for the neighborhood traffic calming program are described in the Procedures element (PDF).

If you have any questions about the Traffic Calming Program, call (503) 526-3726.

Traffic Calming Program

Table 1 (PDF) shows the effects of recent traffic calming projects on traffic speeds and traffic volumes in various neighborhoods. The table shows both the 85th percentile speed (meaning that 85% of the vehicles were going at or below this speed) and the percent of vehicles exceeding the posted speed limit.

The traffic calming program is intended to improve compliance with the posted speed limits. It is not intended to require drivers to travel significantly below the speed limit. Most vehicles should be able to travel through a traffic calming area at the speed limit.
