Safe-D: Safety through Disruption

An Evaluation of Road User Interactions with E-Scooters

 

Abstract

This research project will investigate road user interactions with e-scooters. The primary objective will assess e-scooter rider interactions with other road user by data mining the VT E-Scooter Deployment project fixed camera video database that is currently being collected on Virginia Tech campus in Blacksburg. The VT E-Scooter Deployment project is a joint venture with Spin and VTTI to assess safety, convenience, and nuisance factors that may occur with the deployment of e-scooters on a college campus. Using three or four strategically located fixed cameras located proximal to campus bus stops, the data will be reviewed to 1) determine e-scooter presence 2) capture e-scooter interactions with other road users, 3) classify these interactions for severity and 4) record general behavior of e-scooter riders (e.g. helmet use, backpack/carriage of other items, speed, following general rules of road). Analyses will provide greater understanding of e-scooter rider interactions with other road users and potential countermeasures to improve safety for all road users.

Project Highlights

  • The analysis showed that e-scooters pose the most threat to pedestrians due to their higher speed and the greater vulnerability of pedestrians.
  • The results also showed that the e-scooter riders adjusted their operation rules based on the traffic environment.
  • These results suggest it might be safer to operate e-scooters in designated lanes, bike lanes, or on roadways with a speed limit of 25 mph or less. Additional countermeasures to separate e-scooter traffic from vehicles may be required on roadways with faster speed limits.
