Abstract
The motive of this study is derived from the problem recognition that the headway of passing vehicle in signalized intersection cannot be merely determined by departing sequence. Traffic speed and headway data of passing vehicles in signalized intersection have been obtained by using magnetic detector (NC 97) and detecting program, and the data was analyzed. Without special treatment, the model established on passing behavior of vehicles was meaningless by the viewpoint of statistic analysis. So, special treatment such as filtering (upper 85% offensive driver driven vehicle's) and log scaling of data was carried on. With this filtered data, meaningful model (where coefficient of determination is 0.91) was established. This model explained the fact that vehicle headway is affected by not only the speed and headway of previous vehicle, but also the speed of itself in a signalized intersection.
