Evaluation Of Public Transport Operation Based On Multi-Source Data

In recent years,with the public awareness of environmental protection gradually increased,public transport has become the main way for residents to travel.As a major means of public transport,the quality of the bus is particularly significant in the increasingly congested traffic environment.However,there are some problems with the existing methods of evaluating the bus's operating conditions that affect the final evaluation results,for example,messy evaluation methods and indicators,and strong subjectivity.Based on the operational data of bus,this paper puts forward the evaluation method of bus operation status based on operating data on the basis of data processing and data processing of MySQL and MATLAB.The method is based on the concept of fuzzy mathematics and hierarchical analysis.First of all,according to the screening criteria method to select the appropriate evaluation index and calculate the index value on the basis of summing up a number of evaluation indicators.Secondly,construct the comprehensive evaluation method of bus operation based on the theory of fuzzy mathematics.And then use the data of bus operation in Jinan to verify the comprehensive algorithm.At last,design platform system based on the software programming language.This paper is based on the multi-source bus operation data including bus GPS data,bus IC card data,GPS related auxiliary data and field survey data.Bus GPS data and IC card data as the main research data are used for calculation with the help of other data by a certain method.On the basis of summarizing the indicators used to evaluate the bus operation status,this paper constructs the evaluation index system with the station,the section and the whole line as the criterion level through certain screening method.And the method of calculating the index value is divided into two methods:the index value of the map matching and the index value calculation without map matching.Then calculate the index value using the calculation methods.In this paper,we use the fuzzy comprehensive evaluation method to evaluate the bus operation status,and the method can be divided into five steps:construct the evaluation factor set,build the evaluation grade set,set up the membership degree matrix,single factor evaluation and comprehensive evaluation.There are two forms in the evaluation grade division consist of dynamic division and static division.And use AHP to calculate the index weights.Based on the analysis of the function of different modules and the design of the system,this paper uses C#,MySQL and other software to complete the system development.
