Urban bus network OD matrix construction method

Abstract

The invention discloses an urban bus network OD matrix construction method. The method comprises the following steps of acquiring the vehicle information of each bus in a city and the corresponding number of passengers on the bus, and drawing a data broken line graph which takes time as an abscissa and the number of passengers as an ordinate; acquiring the GPS signal of each bus in the city and drawing the GPS signal scatter diagram of each bus; and according to the acquired data broken line graph and the GPS signal scatter diagram, calculating the travel rules of urban people and drawing a ODmatrix graph. In the invention, through the number of passengers of each bus, the data broken line graph is acquired; through the GPS signal of each bus, the GPS signal scatter diagram is acquired; and finally, the data broken line graph and the GPS signal scatter diagram are taken as bases so as to draw the OD matrix graph so that the integrative, comprehensive, objective and accurate assessmentof the appearance data of multiple buses is realized and processing accuracy is high.

Description

technical field [0001] The invention relates to the technical field of urban intelligent transportation, and more specifically relates to a method for constructing an OD matrix of an urban public transport network. Background technique [0002] With the rapid development of the social economy and the continuous expansion of the city scale, practitioners from all over the country are constantly pouring in, and the urban population is also increasing. In the Pearl River Delta region, this phenomenon is even more obvious. [0003] However, when urban traffic cannot catch up with the development of population and economy, urban traffic will gradually become an important factor hindering urban development. Urban traffic conditions have a crucial impact on urban planning, residents' sense of belonging to the city, and city brand. Conventional public transport is the main body of urban traffic. As a part of urban public transport, ground public transport is an important means of t...

Problems solved by technology

However, the current urban public transportation still has a lot of room for improvement.

[0004] At present, in order to optimize the configuration of the urban public transport network, the staff of the relevant departments usually use the OD matrix as the basis for optimizing the urban transport network. The so-called OD matrix refers to the information of the bus trip volume. The acquisition of the OD matrix in the prior art is limited to a single line The statistical analysis of the probability model is difficult to comprehensively, comprehensively, objectively and accurately evaluate the massive bus data of multiple bus lines, and the processing accuracy is not good
