The Bike Path Radar: A Dashboard to Provide New Information About Bicycle Infrastructure Quality

Data can support the decision making process in bicycle infrastructure planning. Dashboards may make a positive contribution to learn more about infrastructure shortcomings if these provide relevant Key Performance Indicators (KPIs) and visualizations. Existing dashboards do not reflect the perspective of different types of users, only provide limited data sources and do not provide much information about bike path damages. The Bike Path Radar (Radweg Radar) should fill this research gap by providing relevant information about cycling infrastructure. The frontend enables the end user to create different KPIs regarding cycling accidents, citizen reportings, traffic volume etc. of highest interest. A role concept enables the provision of a suitable degree of information traffic planning experts and citizens. The most important KPIs were identified based on expert interviews. The dashboard is connected to a database in the background that includes heterogeneous cycling and bicycle infrastructure data by an API. In addition to that, the dashboard gives new opportunities for citizen engagement. Users can upload images of bike path damages in a reporting tool. The images will be processed by an object detection algorithm. The detected damages will be displayed on a map by a marker to find locations with surface shortcomings. This contribution will give a short overview about the current state of development of the Bike Path Radar. The outlook provides some additional information about the forthcoming working steps.
