Embodiment Construction

[0055] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0056] The present invention provides a method for determining the departure flow threshold of a rapid-conventional bus shared lane. The collinear section of the bus line is the research object, and the method of determining the threshold condition for independent or shared dedicated lanes between BRT and conventional buses under specific traffic conditions can provide a reference for the shared setting of BRT dedicated lanes and conventional buses.

[0057] Using the method in this invention, the present invention will be further described in conjunction with specific examples. A method for determining the traffic flow threshold of a fast-conventional bus-sharing lane, comprising the following steps:

[0058] Step 1. Obtain the data of related factors and parameters: including the departure volume of BRT lines, the average distance between int...

Abstract

The invention discloses a method for determining a departure flow threshold of a conventional-rapid bus sharing lane. The method comprises the following steps of firstly, taking the rapid bus and conventional bus sharing lane as a research object, and taking a departure amount of conventional buses at a specific rapid bus departure frequency as a control index of a threshold, so that constraint conditions of the rapid bus lane sharing threshold are studied; then by analyzing a few types of key indexes, providing an operation time constraint condition, a station queuing probability constraint condition and the road section operation efficiency as three types of constraint conditions; and finally by calculating threshold ranges under different traffic conditions, summarizing a method for determining a threshold condition of the conventional-rapid bus sharing lane. The method aims to explore quantitative conditions of conventional-rapid bus lane sharing setting; optimization method support can be provided for the lane sharing setting; and on the basis that the bus running efficiency of lanes and the overall running benefits of road sections are guaranteed, the advantages of existing road traffic resources are brought into play to the maximum extent.

Description

technical field [0001] The invention relates to the field of urban traffic planning and management, in particular to a method for determining the departure flow threshold of a fast-conventional bus shared lane. Background technique [0002] With the rapid development of my country's economy, the process of urbanization and motorization is accelerating day by day, the gap between the growth rate of cars and the growth rate of road traffic facilities in most cities in my country is widening, and traffic problems are becoming more and more prominent. For most cities, only by developing public transportation, implementing the policy of public transportation priority, and making public transportation the main force of urban transportation, can the traffic problems such as urban traffic congestion be alleviated from the root. [0003] The BRT system is a new form of public transportation, which combines the advantages of conventional public transportation and rail transportation. ...
