Micromobility: Data Challenges Associated with Assessing the Prevalence and Risk of Electric Scooter and Electric Bicycle Fatalities and Injuries

​​​This safety research report examines the data collection and analysis challenges associated with two of the most common types of micromobility devices: electric scooters (e-scooters) and electric bicycles (e-bikes). To do this, the National Transportation Safety Board (NTSB) conducted a scientific literature review; held discussions with subject matter experts; performed an independent analysis of e-scooter and e-bike crashes, fatalities, and injuries in the United States between 2017 and 2021; assessed e-scooter and e-bike injury coding; and reviewed the Infrastructure Investment and Jobs Act, which contains new requirements about collecting data on vulnerable road users, such as e-scooter and e-bike riders. ​
