Abstract

<p>It has been reported that the traffic capacity at freeways are decreasing trend in the last decade. To come up with a viable countermeasure to mitigate traffic congestion and related traffic accident, it is essential to reveal the details of the mechanism of the decreasing trend of traffic capacity. In this study, by using the individual vehicle data, which is collected by traffic detectors in the two-different time cross sections, the differences of the driving characteristics (that is, lane-flow distribution, following time headway distribution, time to collision (TTC), desired speed distribution, and platoon size distribution) between the cross sections are compared. As a result, it is shown that the proportion of traffic volume of the median lane, the following time headway and TTC tend to be larger, whereas the desired speed distribution and platoon size tend to be smaller. These changes of driving behaviors might affect the negative impact of traffic capacity.</p>
