Abstract
A concept of the functionally hierarchical road network has been recognized with the purpose to provide the required service for road of each class. Especially in Japan, practical use of this concept has been intensively discussed from the viewpoint of both mobility improvement of arterial roads and traffic calming in local streets. However, the impact of junctions, which is regarded as a key issue of the hierarchical road network, has not been quantitatively evaluated with the performance of individual roads and further the entire network at planning stage. Therefore, in this paper, a methodology to evaluate the impacts of junction types on the performance of the network is developed by considering junction delay into user equilibrium assignment. By applying it, case studies with hypothetical grid network showed that reduction in junction delays at arterial roads is significant to realize hierarchical road network; and if it is achieved, traffic calming in local roads can also effectively work.
