(Evaluation of the residential areal road safety by using ETC2.0 data and GIS information)

Abstract

When there is a traffic jam on the main line road, in order to avoid this, some vehicles flow into the parallel residential areal roads. . In the previous report, the authors analyzed the relationship between the traffic jam on the main line road in front of the intersection where traffic jam occurs and the traffic volume on residential areal road in parallel with this. And specific safety countermeasures were found from the analysis of the accident occurrence situation. In this report, the authors analyzed the situation of sudden braking and the analysis of traffic accidents for the residential areal roads parallel to the section beyond the intersection of traffic jams. From the results of these analyzes, the authors clarified the dangerous factors, and considered the relationship with the section causing congestion on the arterial road.
