Space-time chain model based bus route evaluation method

Abstract

The invention discloses a space-time chain model based bus route evaluation method. The method includes the steps: firstly, creating a passenger travel station point set; secondly, acquiring a movement track Sij(t) of a bus between two adjacent bus stations Zi and Zj; thirdly, forming a complete passenger travel space-time path L(t); fourthly, modeling the passenger travel time path L(t) by utilizing the time-space geography theory; fifthly, acquiring a mathematical model S' for evaluation of the complete passenger travel space-time path. The bus route and bus travel behaviors are evaluated and expressed visually, and the method has an important value to scientific evaluation and reasonable setting of the bus route.

Description

technical field [0001] The invention relates to the technical field of public transportation, in particular to a method for evaluating public transportation routes based on a space-time chain model. Background technique [0002] The scientific planning of the urban public transport network is the prerequisite for attracting citizens to choose public transport for travel. A scientific and convenient public transport network can improve the operating efficiency of the urban public transport system and increase the proportion of public transport travel. Accurate evaluation of the bus network is the basis of scientific planning and efficient scheduling. At present, the evaluation of technical indicators of the bus network is relatively mature, such as network density, line length, repetition coefficient, non-linear coefficient, accessibility, station density There are already mature calculation methods for the calculation of technical indicators such as passenger flow imbalance ...

AI Technical Summary

Problems solved by technology

At present, there are three main problems in the evaluation methods of public transport network at home and abroad: (1) The existing evaluation methods mainly evaluate the technical indicators of the network itself, such as network density, line length, repetition coefficient, non-linear coefficient , accessibility, station density, unbalanced passenger flow coefficient, etc., and the most critical evaluation standard that can best reflect whether the bus network is scientific and reasonable in practical applications is the travel experience; (2) the existing evaluation methods are mainly based on the city as a whole Or a certain area is used as the evaluation object, and there is no evaluation for a specific bus line. In fact, when the traffic management department sets up a bus line, it requires a specific evaluation for a certain bus line; (3) Existing evaluation Most of the results obtained by the method are a series of tables and technical index numbers, lacking intuitive expression and feeling
