Safety Relevant Behaviour-Based Driving Dynamics Indicators of E-Scooter Usage in Parcours Situations
摘要
E-Scooters provide a fast, easily available, easy to use means of transportation for a broad range of users in urban traffic. Apart from adjustments of rules and policies of E-scooter use, increasing safety for these vulnerable road users is challenging, given driven speeds, handling of e-scooters and the lack of physical protection for E-scooter riders. One approach to understanding the needs of E-scooter users is to study their driving behaviours in everyday and specific challenging situations. The project SEED (Safe E-Scooter Driving) aims to provide and discuss such data, which was collected from more than 80 subjects during an extensive three-day test trial. Three different E-scooters have been used, each equipped with measurement devices to precisely collect data of their motion states. Voluntary test subjects were instructed to pass a diverse driving parcours, including braking manoeuvres. We study the effects of different scooter types on manoeuvrability (indicated by measures such as standard deviation of steering speed and roll-rate or decelerations realized in real conditions), whilst correcting for influences of age, sex and several other parameters on measured driving behaviours. This yields conclusions on what E-Scooter types require which behavioural adjustments to drive safely.
