Pedestrian Route Search Based on OpenStreetMap
Abstract Pedestrians usually walk on sidewalks if available or on special ways where cars are not allowed. The main goal of this work is to enable a route search for pedestrians which mainly orients on sidewalks not on roads. For this, we create a routable graph from OpenStreetMap—consisting of nodes and edges—which exactly represents the ways actually used by pedestrians. Corresponding sidewalk edges as well as zebra crossing edges are constructed and finally connected. In order to enable road crossing not only at dedicated crosswalks, additional equidistant edges are inserted into the graph similar to dedicated crosswalks. Thereby, a safety index value assigned to the crosswalks determines how safe it is to cross the road at a certain location. A mathematical model and a route search method are presented which address both the total distance and the total safety minimization criteria.
