Abstract
Recently the operation of road administration based on performance measurement has been mentioned and there is a rising need for outcome indicators relating to congestion.
In this study, we have tried to analyze the characteristics of data using 20 taxis data operating mainly in the Tokyo wards. In addition, we have derived formulae for three indicators of road performance such as the percentage of time the cars were caught in congestions, traffic jam length and waiting times of signal. We have also estimated performance indicators.
We have shown that this is a highly practical and applicable method that can replace, or improve the efficiency of traditional measurement methods
