The tested vehicles (IMAGE)
Caption
In a recent study, Marco Dozza and his colleagues at Chalmers University of Technology, Sweden, compared a large e-scooter and a light e-scooter with a bicycle (in assisted and non-assisted modes) in field trials to determine whether these new vehicles have different manoeuvrability constraints when avoiding a rear-end collision by braking and/or steering.
The results showed that braking performance, in terms of deceleration and jerk, varies among the different types of vehicles; specifically, e-scooters are not as effective at braking as bicycles, but the large e-scooter demonstrated better braking performance than the light one. No statistically significant difference was observed in the steering performance of the vehicles. Bicycles were perceived as more stable, manoeuvrable, and safe than e-scooters.
