Transportation System Safety Analysis

In 2018 the City hired a consultant to develop the City’s first comprehensive collision analysis, known as the Transportation System Safety Analysis (TSSA). The project focused on developing a baseline analysis for citywide collisions and tools to help the City proactively address current and future priority collision locations and patterns. The project helped to create a foundation for the update of the City’s Transportation System Plan.

• TSSA Analysis Summary
• TSSA Technical Report Summary of Crash Trends

As described in the TSSA documents, the analysis identified specific crash patterns and potential solutions, or countermeasures, to address and prevent crashes within the city. Below are some of the key takeaways from the analysis.

• The majority of crashes in Vancouver are low severity. However, there were 284 crashes involving fatalities or serious injuries between 2010 and 2016.
• More men than women experienced fatalities and serious injuries from crashes.
• Young drivers are the most frequently involved road user group in crashes.
• Approximately 25% of crashes that involved a pedestrian resulted in a fatality or serious injury.
• Distraction/Inattention led to the most crashes across all severities.
• Distraction/inattention, speeding, alcohol and/or drugs, and not using a seatbelt led to the most fatal and serious injury crashes.
• The majority of all crashes and fatal or serious injury crashes are occurring at signalized intersections, and the most common crash types are: rear-end, angle, fixed object, and turning.
• Roads with more lanes (three through six lanes) had more pedestrian and bicycle crashes than roads with fewer lanes. Roads like E. Mill Plain Boulevard, Fourth Plain Boulevard, Andresen Road, and NE 162nd show most potential for responding to pedestrian and bicycle safety countermeasures.
