E-Scooters appear on bike infrastructure: users and usage, conflicts and coexistence with cycling

E-scooters are a rather new mode of transport. Nevertheless, in recent years lots of studies have been published. Replaced modes and consequential environmental impacts as well as specific injury pattern are important topics. Regarding shape, speed and usage, e-scooters are most similar to bikes. As a consequence, by law e-scooters use the same road space or infrastructure than bikes do. Concurrently, in recent years we experience a boom of cycling in cities and a significant expansion of the bike infrastructure. Requirements and frequency of usage on the bike infrastructure are growing in cities caused by increasingly diverse cyclists. At the same time, the bike infrastructure is subject new requirements and additional pressure due to the implementation of e-scooters. In Germany, allowing e-scooters on bike infrastructure can be seen as a paradigm shift since for the first time a motorized vehicle is allowed to use the infrastructure. On this background, interrelation between e-scooters and active mobility (walking and cycling) are very important for the future use of the infrastructure and the ongoing transformation of urban mobility. Hence, we use a multi-method approach to investigate these potential conflicts and draw conclusions for regulation as well as improvement in the system
