Street Story: A Platform for Community Engagement

Street Story is a community engagement tool that allows residents, community groups and agencies to collect information about transportation collisions, near-misses, general hazards and safe locations to travel. The platform and the information collected is free to use and publicly accessible. The tool was created by a team of city planners, public health professionals, engineers, social welfare experts and computer scientists at UC Berkeley’s Safe Transportation Research and Education Center (SafeTREC).

 Street Story Map

Street Story includes a survey about roadway experiences and a publicly available dataset of community input with maps and tables that can be downloaded. The platform allows the public to share information about crashes or near-misses they have been in, and places they feel safe or unsafe traveling through.

Once a report has been made, the information is publicly accessible, and community groups and agencies can use this information as a part of community needs assessments or transportation safety planning efforts.
