A Method Study Of OD Matrix Estimation Of Transit Passenger Flows Based On The Video Information

With China’s urbanization process accelerated, such relevant problems as trafficcongestion has become more and more serious. In this case, the priority to the development ofpublic transport business as a primary means to solve the problem of urban traffic has wonthe acceptance of relevant experts and the urban management department for approval. Aspublic transportation optimization development business improve its operating efficiency thebasic data, the existing public transport travel OD information acquisition means there arestill significant deficiencies. Therefore, explore new public transportation OD informationacquisition methods, to promote the development of public transport operations, then to solveurban traffic problems that goal has the positive significance.This paper based on the analysis of current transit survey method and transit passengerflow OD the advantages and disadvantages, on the basis of proposed by bus on-board Thefront door and back door camera video and passenger information gained by the estimation oftransit passenger flow OD matrices, and obtained the relevant calculation method. Relatedcontents include the following aspects:Papers on common bus travel survey method and transit passenger flow OD accessmethods are summarized, analyzes the advantages and disadvantages of relevant methods.Main drawback include difficulties related to information, relevant information accuracy isnot high, the information processing difficulties, consume a large amount of manpower andfinancial resources. Necessary according to the existing data to explore a kind of reliable andefficient public transport passenger flow OD access method.Proposed to the unloading passengers gained by the bus vehicle The front door and backdoor camera video information is analyzed, according to the video data can be obtained in thepassenger information extraction passengers, characteristic index, qualitative and quantitativeanalysis of the characteristics of passengers indicators, building boarding passengersidentification index system. For passengers to provide the reference feature informationextraction, realize passenger identification index of qualitative and quantitative.Developed based on the bus video information for boarding passengers are definedrespectively using passenger identification index method, data processing, using hierarchical fuzzy matching method is proposed for boarding passengers matching identificationindicators, to obtain a single bus lines bus passenger flow OD matrices and calculate the citybus passenger OD matrix, and design the relevant calculation method.Instance application shows that this method of passenger matching rate is as high as70%above, and to a certain extent, reduced the manpower investment and shorten the dataacquisition cycle of public transport passenger flow OD data obtained. Bus passenger ODmatrix, the method calculated can be used for public transport passenger flow more accurateand detailed basic data for public transport management department for transit planning, linenetwork, site layout, operation management, provides the basis.
