Wies, H. and Beeking, M. (2022): Self-Localization Accuracy of Instrumented Probe Bicycles. In: Krisp, J., Meng, L., Kumke, H. and Huang, H. (eds.): Proceedings 17th International Conference on Location Based Services (LBS2022), Munich / Augsburg, Germany, September 12-14.

Cycling as a healthy, sustainable mean of transport has been getting increasing political attention throughout the last decade. The goal of increasing the share of cycling among different transportation modes requires extensive data on various aspects of cycling. Instrumented Probe Bicycles (IPBs) are equipped with a variety of sensors and are capable to collect the data needed. Use cases for IPBs are for example, to collect data on cycling infrastructure or to take part in car-like assistance and warning systems. One sensor shared by all IPBs is the GNSS receiver. As different use cases often demand different GNSS accuracies, the authors distinguish three accuracy levels ranging from road accuracy (with a positional accuracy < 5m), to cycle lane accuracy (< 0.5m) to pothole accuracy (< 0.1m). The goal is to evaluate different methods to measure the accuracy of a GNSS receiver and further to assess and compare the positional accuracy level of different GNSS receivers.
