Abstract

The paper is based on the HCM's left-turn particular road, and the special channel passage capability model. The head timetable and operational characteristics of the left turn and the head vehicle are analyzed. Taking the main road of Jinan City, the traffic flow of Ten Road has been studied the influencing factors of the proportion of different traffic flow ratios of left-turn vehicles and lanes, and the linear regression method determines the difference between the head, and establishes the relevant calculation model. Combined with the turning head adjustment factor, study the influence factor of the power out of the vehicle and the vehicle traffic flow, and established the traffic capacity calculation model of the intersection of left and turned to the turning lane.
