Final Report

AcciMap Final Version: Fatal E-scooter Collision

Research Brief

Project Slide Deck


Micromobility devices (e.g., standing electric scooters or “e-scooters”) are a rapidly emerging area of transportation worldwide. As these devices become more popular, there has been a coinciding rise in micromobility-related injuries and fatalities. Therefore, this study sought to apply a system mapping tool, the AcciMap, to a fatal e-scooter collision. The purpose of this exercise was to identify the factors that likely contributed to the incident and generate potential countermeasures to prevent similar future events. In addition, this report assessed the strengths and limitations of using the AcciMap approach as a more holistic tool for assessing safety, and future directions for applying the AcciMap approach in a practical setting.
