Apply now for a free Complete Streets Safety Assessment from UC Berkeley SafeTREC

December 15, 2021

The UC Berkeley Safe Transportation Research and Education Center (SafeTREC) is offering free Complete Streets Safety Assessments (CSSAs) to California communities, including cities, counties, and school campuses with a population of over 2,500 people. CSSAs are comprehensive transportation safety assessments that focus on pedestrian and bicycle safety. They help local agencies identify and implement traffic safety solutions that lead to improved safety for all users of California’s roadways.

The Complete Streets Safety Assessment (CSSA)

When a local agency applies for a CSSA and is approved for a study, a team of safety experts in the fields of traffic engineering and planning are assigned to conduct the study for the community. The experts conduct a thorough phone interview of local agency staff and then schedule a virtual or in-person site visit to the city or county. They review available safety data such as Statewide Integrated Traffic Reporting System (SWITRS) and Office of Traffic Safety (OTS) rankings. Based on the available collision data and discussions with local agency staff, a list of intersections and roadway segments with the highest rates of collisions is proposed for the assessment. The experts then visit the city or county to conduct an assessment. The virtual or in-person site visit is conducted at various locations (focus areas), as determined in coordination with local agency staff. The observations made during the site visit are used to suggest policies and physical improvements that could enhance motor vehicle, pedestrian and bicycle safety and accessibility. The experts then prepare a report summarizing their findings and suggestions. The suggestions made in the reports are all customized to each community and their needs.

The CSSAs help agencies in their planning for traffic safety projects. The suggestions could be included into Capital Improvement Projects and Pedestrian/Bicycle Master Plans. One other way the program helps local agencies is by providing a tool for communication among departments within a local agency, as well as with Caltrans and other stakeholders, to discuss opportunities for enhancing safety for all users of public roadways. The CSSAs give agencies a resource or a supporting document for applying for funding. Explore the City of Suisun City Complete Streets Safety Assessment Final Report to learn more about the CSSAs.
