Benicia’s Traffic Calming Program

Two‐Tiered Program

• Minor roads are handled through a neighborhood‐based process.

• Major roads are handled through the City’s Traffic, Pedestrian, and Bicycle Safety Committee.

• Major roads and minor roads have slightly different toolboxes

Major Road Test Case

Approach ‐ Overview

• Flexible approach to outreach

• User‐friendly tools that help citizens understand real‐time effects

Committee Recommendation

• Two‐phased approach, starting with primarily speed control (Scenario I) and moving towards volume control if results are not satisfactory.

• Conduct field tests to measure impact to Fire Department response time. 

Field Tests

• Fire Department brought trucks and ladders to the site.

• Staff placed cones to represent circles and median islands.

• Fire Department did “test” runs with and without the devices.

• Circles added 25 seconds per location, compared to 5-8 seconds as national norm.

Circle Dimensions

Key Learnings

• Fire Department has a valid but very narrow mission.

• Someone at the City (manager or council) needed to balance Fire Dept needs against other public safety and livability needs.

• Field tests should be done with actual devices or very similar.
