Choice Set from the project "Safe bicycle route choice - analysis of the influence of accident risk and perceived safety on bicycle route choice in Germany". The data contains information about the characteristics of the routes and alternatives in three different Cities in Germany (Dresden, Munich, Darmstadt). It contains a total of 112,668 routes (37,556 chosen routes and 75,112 rejected alternatives). The route data contain many attributes relevant for route choice (e.g. information on cycling infrastructure, surface quality, distance and travel time, volume of cycling traffic, traffic volumes of motorized traffic, slopes) and could be used for route choice analysis. The data is available as an anonymous data set without personal reference.
