Calculation method of traffic capacity of intersection approach road under the influence of upstream port stop

Abstract

The invention discloses a method for calculating traffic capacities of intersection entrance lanes under influences of upstream harbor stations. According to the method, an intersection entrance lane related traffic characteristic data set is constructed; a road capacity reduction factor of influences in the process that buses queue for arrival and overflow at the rush hour is determined through analyzing the traffic characteristics in the process that the buses overflow and queue to wait for arrival; a reduction coefficient of influences, on the road capacity, of each bus lane change behavior is determined through analyzing influences, on social vehicle running characteristics, of the bus lane change process; bus lane change frequency, influencing the traffic capacity, of each entrance lane of the intersection is determined through analyzing selection characteristics of the buses at the intersection entrance lanes; and traffic capacities of the intersection entrance lanes under the influences of the upstream harbor stations are determined. Through quantifying the traffic capacities, influenced by the upstream harbor stations, of the intersection entrance lanes, the traffic states of the intersection entrance lanes are better grasped, and traffic jam can be pre-warned in advance, so that the traffic efficiencies of the intersection entrance lanes are improved.

Description

technical field [0001] The invention relates to a method for calculating the traffic capacity of an intersection entrance under the traffic scene of bus operation, in particular to a method for calculating the traffic capacity of an intersection entrance considering the impact of an upstream harbor stop, which belongs to the urban public transport operation management and control technology field. Background technique [0002] With the development of my country's social economy and the continuous acceleration of urbanization, the problem of urban traffic is becoming more and more serious, and the problem of traffic congestion is becoming more and more prominent. In order to better solve the problem of traffic congestion, more and more cities have begun to vigorously develop public transportation. Although the development of public transportation can improve the efficiency of traffic operation, it will also have a certain impact on the operation of social vehicles, especiall...

AI Technical Summary

Problems solved by technology

Although the development of public transportation can improve the efficiency of traffic operation, it will also have a certain impact on the operation of social vehicles, especially in the bottleneck area "intersection" of social vehicle operation, the setting of bus stops will be greatly affected. Reduce traffic efficiency of downstream intersection approach roads
