Abstract: Link travel time is crucial for finding the fastest path in a road network which is an issue in many fields of research. Readily available data sources like OpenStreetMap (OSM) often lack information about the maximum speed of a road which is needed to calculate link travel time. In rural regions, the average speed of a road depends mainly on two parameters: slope and road quality. In this paper, we develop a fuzzy control system (FCS) which estimates link travel time based on these two input parameters. The OSM road network and a digital elevation model (DEM) serve as free-to-use and worldwide available input data. Google Directions API data provides a reference for the link travel time. The setup of the FCS as well as its tuning and validation is described in detail. Furthermore, two approaches to derive slope from a DEM are presented and compared. The FCS is applied exemplary for the BioBío region in central Chile. The results of the case study reveal the potential of this approac h. Link travel times are estimated by the FCS with an R2 of at least 87.8 %. In future work, the FCS can be designed with more input parameters to achieve an even better performance. (More)
