The Application of Probe-based Traffic Efficiency Evaluation to Actual Operations
In Japan, one of the most important challenges among the goals of road administration policies is to make traffic more efficient. The authors aim to do this through measures including road administration management. Advances in Intelligent Transportation System (ITS) technology in recent years have enabled us to obtain private-sector probe data, which can be used to evaluate traffic efficiency scientifically and efficiently, and then propose required measures. This paper reports on the use of private-sector probe data for evaluating the efficiency of traffic and then raising the efficiency. The findings showed that regarding time lost due to congestion, the evaluation was based on lost time in “intersection units” instead of “section units” as in the past, permitting more accurate evaluations. The findings also showed that it is possible to perform a detailed analysis of traffic efficiency to identify bottleneck intersections and to clarify the range of congestion impact, which were difficult to clarify by conventional test car traveling surveys.
