Task 3 – Analyze Bicycle Collision Data

Task 3 – Analyze Bicycle Collision Data
Fehr & Peers will collect, map and analyze records of bicycle collisions from California Highway
Patrol reports filed in the Statewide Integrated Traffic Records System (SWITRS). We will
review reports from the past five years, create a GIS bicycle collisions database, and analyze the
collisions by several factors, such as location, crash type, parties involved, age, time of day, and
primary collision factor.

Based on this analysis, we will recommend safety improvements to existing roads, paths, and
other bicycle facilities. We will also recommend internal procedures that the City can undertake
to analyze collision data (regularity, department responsibilities, etc.), practices for conducting the
analysis (queries to conduct, procedures for identifying “hot spots,” practices for conducting
audits), and practices for information sharing (to assure that the data reaches the appropriate
internal people and identify which data can be posted for public consumption). This analysis will
also inform the education and enforcement components of the Plan.

Deliverable(s): Technical memorandum including analysis and GIS mapping of bicycle-vehicle
collision data, and recommendations for internal procedure on collision analysis practices.
