What is Understanding Impact of Angle in Urban Transportation about?

Traffic congestion at urban-scale levels occurs when road network supply is insufficient compared with demand. Therefore, the relationship between supply and demand has been extensively investigated in the literature. Especially the impact of a network's topology (i.e., connectivity) on traffic congestion has been widely studied. On the other hand, only a few studies analyze the relationship between the physical shape of the road network (i.e., morphology), demand, and congestion. For example, angular indicators associated with links and trips can be utilized to characterize such morphology. However, statistical analysis of angular indicators requires a specialized methodology called Directional Statistics, and how to apply Directional Statistics to traffic data is not obvious. Here, this study develops a descriptive model of traffic congestion based on Directional Statistics. It describes direction-dependent congestion levels using angular distributions that characterize the shape of road network and travel demand. Specifically, the shape of road network is characterized by the distribution of angles of each road link in a specific region. Likewise, the travel demand is characteri
