The development of electric vehicles has made it increasingly difficult to share urban layout facilities. The purpose of this study is to understand the profiles of personal and free-floating electric scooter users, their behaviours and their risky situations. Forty-one users of e-scooters were recruited, and three data collection methods were combined during one month: 1) recordings of all their routes using a camera fixed on the chest, 2) completion of a logbook describing each route and critical situation, and 3) an interview per week based on the logbook and the video recordings to deepen the user’s behaviours. Results showed that even if the distance traveled for personal e-scooters users is double the distance traveled by free-floating e-scooters users, the routes are relatively short for both users. There were a couple of differences in terms of usage: type of route, wearing of safety equipment, and relation to the rules. One hundred and twenty-six risky situations were collected during a month. Participants mainly considered other road users responsible for the risky situations, particularly car drivers (44%). The riskiest layouts are the bike lanes on the road (26%) and the shared road (24%). The most frequently risk scenario encountered by these users is «encroachment of another user on a lane or presence of a stationary user» (29% of all critical situations). These data are necessary for the formulation of public policies in order to promote, supervise and design urban layouts and facilities including those for e-scooters users.
