Quantitative Analysis of Impact of Vehicle-Bicycle Conflict on the Capacity in Urban Mixed Traffic

Abstract

In order to determine the impact of vehicle-bicycle conflict on the capacity, this interference on the capacity is divided into three states: no interference, weak interference and strong interference, and quantitative analysis of the influence of capacity under the three states. Based on the data about interference of vehicle-bicycle conflict in typical road section in Xi’an, this paper quantitatively analyzes the velocity changing tendency of vehicles under three different interference states, determine the critical value of three different interference state, and the coefficients of interference can be calculated. As a result, the analysis based on the sample data about interference of vehicle-bicycle conflict in typical road section, this sample data shows that the coefficients of interference are significantly different under the different degree of vehicle-Bicycle conflict, not in a fixed value. Therefore, this paper provided a theory basis on capacity computation for condition about different vehicle-bicycle conflict.
