Abstract

<p>A road network around a railway station may affect the convenience of the station. However, only few researches have evaluated or classified a road network around a specific facility with referring to tangible factors of a road network such as length or orientation of each road link. In this paper, we propose a new evaluation method of a road network by using directional statistics. At first, we draw a rose diagram focusing on orientation of road link around a station. Next, we estimate parameters of circular distribution of the orientation and evaluate characteristics of the network by using the parameter values. The proposed model is applied to the road networks around all 21 stations on Tokyu Toyoko line. In comparison with the past studies, this method represents how the link orientations concentrate to specific directions. In addition, it becomes possible to classify road networks into several categories with similar parameter values.</p>
