On the Speed Characteristics of Traffic Flow in No-passing Zone

Creators Tamura Yoichi

In this paper, some speed characteristics of road traffic flow in no-passing zone are reported. The speed distribution of leader cars and that of following cars were approximately to the normal distribution. The mean of speeds of leader cars were higher than that of following cars, and the variance of speeds of leader cars were slightly smaller than that of followers. Most of both drivers exceeded the limit speed, and this tendency became stronger when geometric condition of road became more satisfactory. And leader speeds became slower, number of following cars increased, and bunch size became larger, speed of bunching cars became slower. In this study, distinction of leader cars and following cars based upon the critical time headway h_c=3.0 sec.. More details were discussed in the following articles.
