At present, researchers and car manufacturers are focusing on the implementation of automated vehicles in road transport, which leads to mixed traffic containing automated vehicles and manual drivers. To realize this project, it is essential to understand the communicational processes and the interaction of contemporary road users. This paper focuses on investigating the interaction at bottlenecks caused by obstacles on both sides of the road, for instance due to double parking. The authors explore how drivers communicate to a simultaneously oncoming vehicle that they intend to pass through the narrow section first. As a method, a traffic observation was conducted. The results show that drivers almost exclusively use implicit means of communication. Moreover, four different interaction strategies could be found. Based on the underlying observation data, the authors provide recommendations on how automated vehicles might communicate implicitly by adopting the communication processes observed in the field study.
