Study on the Application of One Way Traffic Organization for Narrow High Frequency Road Sections—Take Yutuo Road in Lhasa as an Example

Abstract

By analyzing the characteristics of single traffic and the current utilization of branch roads in urban road system, this paper takes narrow high-frequency road sections as the optimization object of single traffic organization and branch roads as the auxiliary optimization object to reduce road load. The TTI method is used to calculate the index when the road is congested, and the saturation of the road section is calculated. At the same time, considering the impact of intersection delay on one-way traffic and path selection, the traffic signal timing scheme at the intersection is calculated.
