Road safety is influenced particularly by three factors: human behavior, transport planning, and vehicle development. Electric vehicles and their interaction with non-motorized road users require new considerations in terms of road safety due to their specific characteristics like quicker acceleration and lower acoustic perceptibility due to missing motor noise. COEXIST investigated the effects of an increasing number of electric vehicles on the immediate traffic behavior in a multi-modal traffic scene and thus, on road traffic safety. The aim of the project was to determine which requirements arise for the urban and transport planning as well as which measures can counteract the expected higher traffic risks. The first part of the project dealt with the identification of potential hazard areas and the perception of road users about subjective safety. In addition to a comprehensive literature review of existing studies, statistics and applicable guidelines, test runs and surveys were implemented to get the desired data. Therefore road users were interviewed in street areas. Also test runs with electric vehicles were organized, where additional findings were derived from questionnaires. Based on the data obtained in the first part of COEXIST, the aim of the second part was the development of a profound basis for decision makers. The risk factors of electric mobility were cited in a first step, followed by an analysis of the impacts of electric vehicles on the potential hazard areas in the transport system. Finally, possible solutions and prevention tools were developed to support the coexistence of all road users without serious conflicts; although there is an increasing number of electric vehicles on the roads.
