Passing Stage Division of Bicycle Groups at Signalized Intersection
This paper presents a simple identifying method of bike group ,then takes bicycle groups of signalized intersection as the research object, investigations and video cameras are carried out at two signalized intersections in Beijing and Tianjin city. For the data analysis,by using K-means cluster analysis method ,this paper selects three criterions which are the average speed of bicycle group,the width of bicycle group and the length of bicycle group. Based on three indexes , the passing stage of the bicycle groups at two signalized intersections of Beijing city and Tianjin city are divided into three stages :the first stage for bicycle group gradually spreading ,the second stage for expanding ,the third stage for gradually shrinking.The research on the passing stage of bicycle group starting and running through the intersection at the signalized intersection are useful for determining the capacity of vehicles with the impact of bicycle , and for calculating the signal timing of bicycle under the mixed traffic flow condition at signalized intersection.
