The interaction between and with (electric) bicycles at intersections

There are more and more different types of users on the bike path. As a result, differences in width, speed and mass of bike path users also increase. In addition the bike path is getting more and more crowded. The combination of these aspects is potentially hazardous, on the bike path itself as well as on locations with intersecting traffic.

Research questions

  1. What kind of interactions between electric bikes and other users of the bike path (e.g. intersecting traffic) take place at intersections and which types of conflicts/incidents occur?
  2. What are the interactions between cars and cyclists like and what is the role of infrastructural characteristics and of certain stereotyped images of other road users?

As part of her PhD research, Tamara Hoekstra will focus specifically on the research of interactions between cars and cyclists, infrastructural characteristics and stereotyped images of road users. The study of interactions between and with electric bicyclists will largely be conducted by Agnieszka Stelling.


Cyclists are responsible for approximately one third of the total number of road fatalities and 60% of the total number of serious road injuries. Particularly in the field of the bike developments are to be expected in years to come. For example, the increasing popularity of electric bikes, speed pedelecs and light mopeds and the increasing speed differences with conventional bicycle traffic that come with it. It is expected that these developments will lead to more conflicts, especially at intersections, not only with intersecting motorized traffic but also on the bike path just before and immediately after an intersection.

The study will yield important knowledge for the national government, for example in connection with laws and regulations (speed limit, place on the road and helmet requirements for fast electric bikes), and for local governments, for example when it comes to investments in cycling infrastructure and application of newer concepts such as Shared Space and bicycle streets. The study will also provide handles for education and information and for influencing methods of social psychology (e.g. perspective training).
