AN INDUCTIVE CONSIDERATION ON A RELATIONSHIP BETWEEN SPATIAL SPEED CHANGE AND TRAFFIC CONGESTION AT MOTORWAY SAG SECTIONS

Traffic congestions often appear on sag sections of rural motorways, in Japan. The occurrence of these traffic congestion are that a large platoon with higher flow rate, which exceed a capacity of the section, arrives in a moment, and a significant speed drop of a large platoon leader. It can think that these conditions relate to mutually, and contribute to traffic congestion occurrence. However, a degree of contribution of each condition to traffic congestion occurrence sometimes changes on every sag section. As a result of the running car experiments, it became clear that a significant speed drop of a platoon leader that influences a traffic congestion occurrence varied in every sag sections. At the same time, it influenced a traffic congestion occurrence that a distance between a kind of motorway facilities and /or structures, that form of a platoon size and are making a rectification of traffic flow, and sag sections. In this paper, an inductive logic that a mechanism of traffic congestion occurrence is developed about some typical sag sections, where the traffic congestion occur frequently, is proposed based on the running car experiments.
