OD matrix-based specific time multi-traffic-mode travel distribution analysis method

Abstract

The invention discloses a specific time multi-traffic-mode travel distribution analysis method based on OD matrix backstepping, and belongs to the field of traffic planning. The method comprises the following steps: (1) selecting a research area and a specific time period; (2) dividing traffic zones of the research area; (3) carrying out questionnaire survey and establishing a travel database; (4) calculating an initial matrix of travel distribution of various traffic modes; (5) collecting motor vehicle traffic volume data of key road sections; (6) calculating the equivalent total traffic volume of motor vehicles on the key road section; (7) calculating a motor vehicle traffic mode equivalent total travel distribution initial matrix; (8) calculating a motor vehicle traffic mode equivalent total travel distribution matrix; and (9) calculating a travel distribution matrix of various traffic modes. According to the method, questionnaire survey and road section traffic volume data acquisition are closely combined in the aspects of traffic occurrence time, space, traffic modes and the like, and spatial distribution of various traffic modes in a specific time period can be analyzed more accurately.

Description

technical field [0001] The invention relates to the field of traffic planning, design and management, in particular to a method for analyzing travel distribution of multiple traffic modes at a specific time based on an OD matrix. Background technique [0002] With the rapid development of the economy, the continuous growth of the people's demand for transportation, and the improvement of the quality requirements for daily transportation, the contradictions among the elements of the transportation system, including people, vehicles, roads and the environment, have become increasingly prominent, which has greatly affected the efficiency of transportation. and the sustainable development of the transportation system. Therefore, it is necessary to put forward higher requirements for residents' travel analysis, so as to build a transportation system in a more scientific, reasonable, efficient and green way to meet residents' travel needs. [0003] The analysis of residents' trav...

Problems solved by technology

[0005] The invention provides a travel distribution analysis method based on the OD matrix inversion of multiple transportation modes at a specific time, which can effectively solve the technical defects of the traditional large-scale resident travel questionnaire survey, which is time-consuming and laborious, and the OD matrix inversion results are single and poor in practicability.
