Complete Streets Safety Assessments

For California Communities

The primary objectives of Complete Streets Safety Assessments are:

  • To improve safety for all modes of travel in a city or county, with emphasis on pedestrian and bicycle safety
  • To create safe, comfortable, accessible, and welcoming environments for all road users 
  • To enhance the walkability, bikeability, and economic vitality of local districts

To achieve these objectives, Tech Transfer provides free Complete Streets Safety Assessments to California local agencies.  We send expert evaluators to review traffic, pedestrian, and bicycle safety conditions, programs, and needs of your agency, and suggest new strategies to improve safety for all road users, with emphasis on pedestrians and bicyclists.  Tech Transfer provides highly-focused, in-depth, expert safety reviews of problem areas and specific suggestions for pedestrian and bicycle safety improvements. This free technical assistance service also helps local agencies identify potential sources of funding to make the suggested improvements, and justification to use in grant applications for state and federal funding.

Who can request a Complete Streets Safety Assessment?

California communities with populations over 25,000 with significant pedestrian and bicycle safety issues may request a Complete Streets Safety Assessment from Tech Transfer.  Priority is given to applicant agencies that appear in the highest collision rates (top ten lists) for OTS collision rankings.  California agencies can review their OTS collision ranking online.

How is the Complete Streets Safety Assessment conducted?

If a local agency is selected by Tech Transfer and approved by OTS for a CSSA, Tech Transfer will assign a team of two safety experts (evaluators) in the fields of traffic engineering, planning, or traffic enforcement, depending on the needs of the local agency, to conduct the study for the community.

The evaluators will begin with a thorough phone interview of local agency staff and then schedule a one-day visit to the city or county to observe pedestrian and bicycle traffic conditions in the field. As part of the assessment, the evaluators will review the community's pedestrian/bicycle safety programs, with a view to increase the overall effectiveness of the programs.  They will also review 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 pedestrian and bicycle collisions is proposed for the evaluation.   The evaluators will then visit the city or county for one day to conduct an evaluation using the comprehensive “A Technical Guide for Conducting Pedestrian Safety Assessments for California Communities” and “A Technical Guide for Conducting Bicycle Safety Assessments for California Communities.” to help the community achieve their objectives listed above. The site visit is conducted at various locations, as determined in coordination with city or county staff. The observations made during the field audit are used to suggest policies and physical improvements that could enhance pedestrian and bicycle safety and accessibility, and in some instances, economic vitality, and then suggest new strategies to improve safety for all modes of transportation in the community. 

After completing the one-day visit, the two evaluators prepare a report summarizing their findings and suggestions. This report presents the findings and suggestions for improvements derived from:

  • Benchmarking analysis of the community's existing pedestrian and bicycle programs, policies, and practices, which aims to provide the community with information on current best practices and how the city or county compares
  • Field walking and biking audits at various locations in the city or county
  • Discussions with and data provided by the local enforcement regarding their practices for pedestrian and bicycle safety

Many suggestions in the CSSA report may be appropriate for grant applications, including OTS grant or Safe-Routes-to-School funding. The suggestions for improvement may also be used as the starting point for a Pedestrian/Bicycle Master Plan, a document that would set forth pedestrian/bicycle and streetscape policies for the community and identify and prioritize capital improvement projects.
