SimRa: The first results for Berlin are published

The SimRa research project published the first results for Berlin in August 2020. Since the start of the project, 18,350 trips have been recorded and 17,358 (94.6%) of these have been analyzed.

An interactive result map shows all road sections and intersections displayed (OSM type "Highway") for which either a) at least 50 trips or b) at least 10 trips and a hazard score of 0.25 or more are available. The research team around Prof. Dr. David Bermbach used this map for analysis to create the danger zone reports. On the map, users can click on road sections and intersections to view the recorded incidents.

Another results map shows all road sections and intersections (OSM type "Highway") in Berlin for which at least 10 trips are available. You can also click on road sections and intersections on this map to display the recorded incidents.

Among the investigated incidents are:
Overtaking too close
Vehicle entering or leaving the parking lot
Near-turning accident
Accommodating road user
Too close approach
Avoid obstacle

In their presentation, the researchers mention possible solutions for specific road sections and intersections. These should be seen as a basis for discussion and not as immediate recommendations for implementation. A corresponding analysis on site by traffic planning experts was not carried out. The section between Havelchaussee and Königstrasse on Kronprinzessinnenweg, for example, is classified by the researchers as "medium-high" in terms of danger. A frequent danger reported by cyclists at this point is the dense overtaking by cars. "The Kronprinzessinnenweg between Hüttenweg and Havelchaussee is closed for motorized traffic - this regulation should be extended to the entire Kronprinzessinnenweg, since this is very popular with day-trippers," advises the research team.
