Land readjustment project of Sapporo Station is carried out in these years. This project includes the construction of new station with high-rise hotel and the large-scale shopping mall. Due to this, traffic environment will be deteriorated around station area. The purpose of this paper is to evaluate traffic regulation policies that overcome such traffic problems caused by the project.
A comprehensive model combined with 2 steps assignment method and the method considering signal effects that authors developed enforced the evaluation. The assigned traffic volumes were estimated in case of two alternatives of road networks, that is, the case of pre-project and the case of post-project. These cases include several regulations that authors invented. The evaluation was enforced comprehensively in term of 2 indexes, namely, intersection saturation degree and total traveling time.
As a result, the following points were concluded: (1) Traffic regulation policy that prohibited both the right-turn outflow from the redevelopment area and the right-turn inflow into the same area was the most effective. (2) The other policies brought the increase of circuit traffic. At the same time, they took long total traveling time and had no reduction of affects on intersection saturation degree.
