Problems solved by technology

However, there are some problems in the inter-arrival reliability indicators proposed by existing studies. For example, the index value will be less than 0 and greater than 1, which conflicts with the definition requirements of reliability indicators; lack of hierarchical evaluation indicators, it is difficult Meet the requirements of bus operation evaluation

Embodiment Construction

[0040] Below in conjunction with accompanying drawing, the present invention will be further described:

[0041] Since the calculation of the reliability of urban bus arrival intervals requires many parameters, here is a detailed description of them:

[0042] A. Preliminary parameter determination of urban bus arrival interval reliability calculation method

[0043] a. Determine the scope of evaluation objects according to the evaluation requirements, including site collection, line collection, time period collection, and vehicle collection (i∈I, j∈J, k∈K, m∈M). The time period here is mainly for the middle of the day different periods of time, such as peak hours, off-peak hours or other divisions;

[0044] b. Collect data and information related to the driving plan according to the evaluation scope, mainly the planned arrival interval H ijkm ;

[0045] c. Establish the data source of urban bus arrival interval on the evaluation date and evaluation period, and obtain the ar...

Abstract

Aiming at the conventional bus lines of which the bus dispatch frequency is less than 30 minutes, the invention provides a method for acquiring the arrival interval reliability of an urban bus. In a process of defining the arrival interval reliability of the urban bus, various definition features of the conventional reliability are fused; the running reliability of a station bus under different arrival intervals is determined by using a segment calculation method; reliability weight values of different buses at different stations on different lines are determined by planning the arrival interval, the flow and the like; and the bus arrival interval reliability index calculation method is provided based on a station layer, a line layer and a network layer. By the improved method for acquiring the arrival interval reliability, the shortcomings of the conventional method for acquiring the index of the arrival interval reliability can be well overcome; the method is easy to operate; the calculation result is rational and can reflect the actual running characteristic of the bus; and the method is relatively high in practical value.

Description

technical field [0001] The invention relates to a method for obtaining the reliability of the arrival interval of urban public transport vehicles. Background technique [0002] The reliability of urban bus transportation refers to the probability that a bus will transport passengers to their destination safely and comfortably within a specified time under a certain service level. It is an important indicator to measure the quality and operation of urban conventional bus services. Reliability affects passengers' overall travel time, platform waiting time, and the time consistency of passengers arriving at their destinations every day. Reliability plays an important role in the selection process of passengers' travel modes and travel routes. [0003] At present, foreign related studies have discussed the methods of analyzing the reliability of bus transportation by using different indicators such as on-time rate, departure interval reliability, arrival interval reliability, an...
