Free Traffic Safety Evaluations for California Communities

Tech Transfer has offered evaluations to California cities and counties for more than 20 years.

The primary objective of a Traffic Safety Evaluation (TSE) is to improve traffic safety in a city or county. Improved local enforcement and engineering practices and programs can reduce traffic collisions that cause injury, death, and property damage. To achieve these objectives, Tech Transfer provides free Traffic Safety Evaluations, in which evaluators will review your city or county's traffic safety conditions, programs, and needs, and suggest new strategies to improve local traffic safety.

Any city or county public works department or police department in California can request a TSE. If the agency is selected for a TSE, Tech Transfer will assign a team of two traffic safety experts, one traffic engineer and one traffic enforcement expert, to conduct the TSE. The evaluators will begin with a thorough interview of local agency staff and then schedule a one-day visit to the city or county to observe conditions in the field. Following the visit, the TSE team will prepare a report presenting their findings and suggestions to improve traffic safety and traffic operations in the city or county.

Funding for this program is provided by a grant from the California Office of Traffic Safety (OTS), through the National Highway Traffic Safety Administration.

What kinds of safety issues can the evaluation address?

Engineering topics that communities have asked our evaluators to address include the following:

  • High-collision intersections
  • Inadequate sight-distance
  • Speeding problems
  • Speed-limit posting
  • Red-light running
  • Need for additional traffic control devices (signals, signs, markings, striping)
  • Roadway channelization and road diet
  • Traffic circulation
  • Signal timing
  • Access management
  • Traffic calming
  • Speed surveys
  • Traffic record keeping

Enforcement topics that communities have asked our evaluators to address include the following:

  • Enforcement capabilities and improvements
  • Local enforcement resources
  • Police personnel training
  • Driving Under the Influence (DUI)
  • Hit-and-run collisions
  • Speeding
  • Intersection/right-of-way enforcement
  • Vehicle impounds
  • Seat belt usage
  • Resource deployment
  • Traffic record systems
  • Reporting of collision factors
  • Safety and enforcement goals
  • Public relations and education

How is the evaluation conducted?

A team of two traffic safety experts reviews available safety data such as Statewide Integrated Traffic Reporting System (SWITRS) and Office of Traffic Safety (OTS) ranking.

Based on the available collision data and discussions with city and county staff, a list of intersections and roadway segments with the highest rates of collision is proposed for the evaluation. The team meets with key police and engineering staff to identify local issues, and then performs a site review of roadway safety conditions. After a second meeting with police and engineering staff, the team prepares a written report to document findings, suggestions for improvement, and other relevant information.

Who can request a Traffic Safety Evaluation?

Any agency within a city or community in California may request a Traffic Safety Evaluation from Tech Transfer. However, the number of evaluations we can do each year is limited by funding from OTS. Priority is given to applicants with significant traffic safety issues based on OTS collision rankings. Communities with the highest collision rates (top ten) for their population group are given priority. Communities with populations over 25,000 that appear in the top ten lists for OTS collision rankings are given the highest priority. Agencies can review their OTS collision ranking online.

What have other agencies said about thier Traffic Safety Evaluations?

"The evaluators were very professional. They met the city personnel and listened to our issues. They responded accordingly and did not present any information which was non-relevant. Their report was presented in an efficient format."
"The team did a great job in first understanding what the city's main areas of concern were. Once they had a list of areas, they went out and evaluated the locations. Their comments provided us with an additional perspective on areas that we could improve in order to increase safety. Overall, they exceeded our expectations."
"My overall perception of the work performed by the TSE team is one of great satisfaction. Their report was very thorough and addressed the traffic safety concerns we had."
