Bus service level evaluation system and method

Abstract

The invention relates to a bus service level evaluation system and method. The system comprises a passenger arrival density acquisition unit, a bus service level evaluation index table acquisition unit and a bus service level evaluation level acquisition unit, wherein the passenger arrival density acquisition unit takes an arrival passenger number at the midpoint moment in the arrival interval oftwo adjacent buses of certain line of the corresponding station for each station as passenger arrival density; the bus service level evaluation index table acquisition unit selects the station with intensive bus passengers, obtains the intuitive feeling of the passenger for an arrival time span through questionnaire survey, divides the intuitive feeling into a specific number of bus service levelevaluation index levels from bad to good, and obtains a bus service level evaluation index table; and the bus service level evaluation level acquisition unit utilizes the passenger arrival density tocalculate the expected value of the per capita bus waiting time of certain moment of each station, and obtains the bus service level evaluation level corresponding to the expected value of the per capita bus waiting time as the bus service level evaluation index level of a certain line of the corresponding station at the certain moment.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and in particular relates to a bus service level evaluation system and a bus service level evaluation method based on passengers' waiting time. Background technique [0002] Prioritizing the development of public transportation has become a development strategy to solve the problem of traffic congestion in Chinese cities, meet environmental and energy requirements, and benefit people's travel. Large and medium-sized cities have increased investment and strengthened guarantees in terms of finance and policies. However, the service level of the bus network and the effect of the bus priority policy and financial investment are still questions that the bus industry is difficult to answer with certainty. The main reasons include: [0003] 1) The level of ground bus service lacks a multi-spatial level and multi-time scale quantitative evaluation mechanism, which makes it difficult to intuitiv...

Problems solved by technology

However, on the one hand, the evaluation indicators are interrelated and restrict each other, and the redundancy is high; on the other hand, most of the existing indicators are biased towards static evaluation, ignoring the dynamic change process of bus service in the time dimension; in addition, many indicators The raw data for calculation comes from subjective judgment, and the calculation cycle is long

[0005] 3) In practice, more emphasis is placed on the statistical analysis of the level of public transport infrastructure indicators, and the evaluation of public transport service levels based on passenger perception is often ignored

Existing studies on the evaluation of public transport service levels are mainly based on the selection of evaluation indicators and the improvement of evaluation methods. Usually, comprehensive evaluation methods are used to judge the quality of service levels, and it is difficult to rule out the interference of human subjective factors.

[0009] 3) From the data basis of the evaluation, in the traditional passenger-oriented bus service evaluation, the satisfaction survey is the basic way to obtain the service quality perceived by passengers, but the data collection of the questionnaire survey is difficult and random
