On Link-Weight Calculation of Slow Vehicle Navigation Systems

Abstract This paper presents a link-weight calculation method based on slow-vehicle (SV) probe data for realizing SV navigation systems. First, we analyze the SV probe data from the viewpoint of limiting speed, road width class, the number of traffic lanes, presence/absence of sidewalks, incline, traffic light density, intersection density, and the number of turns. Next, the link-weight calculation formula is shown based on the analysis results. Last, we carry out the experiment for evaluating the effectiveness of the routes computed by the proposed method. The tripartite comparison results show the route computed by the proposed method is more preferred than the commercially available car navigation system and the smartphone application for bicycle.
