Abstract:
There are two types of route maps: deformed route maps, which schematically show the locations and connections of stations and bus stops, and geographically accurate route maps, which are drawn on a map based on the actual locations of routes. While there have been many studies on the automatic generation of deformed route maps, only a few studies have focused on the automatic generation of geographically accurate route maps linked to road networks, such as bus route maps. Most conventional geographically accurate route maps are created manually, but mapping road data to bus route data is complicated by various constraints. In particular, it is necessary to draw parallel routes so that they do not overlap, and to consider the order in which they are arranged so that they cross each other minimally when turning right or left. In this study, we propose an automatic estimation method for bus route maps using bus stop coordinate series and strokes. This method generates bus stop nodes on the road network from the bus stop coordinate series. Furthermore, the bus route is estimated as a route with the least number of right/left turns between the bus stop nodes using the road priority search method. In addition, when drawing multiple routes, the order of placement of overlapping segments is dynamically determined so that there are fewer intersections when turning right or left. This enables the drawing of geographically accurate route maps with fewer intersections at right and left turns.
