Complete Streets Safety Assessments (CSSA)

SafeTREC is offering free Complete Streets Safety Assessments (CSSA) to California local agencies with a population of over 25,000 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 CSSA program is funded by the California Office of Traffic Safety, through the National Highway Traffic Safety Administration. Up until 2018, the program was coordinated by the Tech Transfer program at UCB.

The Complete Streets Safety Assessment (CSSA)

When a local agency applies for a CSSA and is approved for a study, a team of two 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 visit to the city or county to observe traffic conditions in the field. 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, county, or campus for one day to conduct an assessment. The site visit is conducted at various locations (focus areas), as determined in coordination with local agency staff. The observations made during the field audit 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 suggestions include, but are not limited to the following subjects:

  • Traffic signal equipment
  • Traffic signal timing and coordination
  • Sight distance
  • Speed
  • School zones traffic
  • Pedestrian/bicycle facilities 
  • Signing and pavement marking
  • Geometry of intersection/roadway
  • Policies and Procedures 
  • Public Education and Outreach
  • Funding
  • Enforcement 

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.
