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 approach . 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)
