Description

Urban traffic annual physical examination evaluation index system construction method based on multi-source data Technical Field The invention relates to the technical field of urban traffic planning, in particular to a construction method of an urban traffic annual physical examination evaluation index system based on multi-source data. Background At present, planning management of urban homeland space has entered a new stage. According to the relevant notification and regulation issued by the 2021 natural resource department, the city needs to carry out a normalization work of one-year one-physical examination and five-year one-evaluation. Urban traffic physical examination assessment is an important component thereof. In this respect, it has been practiced for a long time in a certain market that annual traffic surveys, multi-source data collection, and annual traffic reports are continuously developed from 2006. However, in the background of the combination of increment and stock planning and the trend of tight constraint of resource environment, the improvement of the existing traffic physical examination assessment system becomes a necessary requirement. With respect to the above, existing traffic physical examination assessment efforts typically involve multiple stages. Firstly, operators acquire resident travel data by means of carrying out annual traffic investigation and the like, and collect traffic flow, public traffic operation and other information from different operation management departments. Then, they manually collate and calculate the collected multi-source data to obtain values of a series of preset indexes such as public transportation trip ratio, commute specific gravity within 45 minutes, etc. Finally, the calculation results and relevant analysis contents are summarized to be compiled into a traffic development annual report, and decision references are provided for urban traffic management. However, the prior art solutions have some drawbacks: Firstly, the existing index system has defects in reflecting the internal coordination of the traffic system, and although the indexes such as public traffic trip proportion and the like are included, the indexes cannot deeply reveal the internal balance and restriction relation between the green traffic trip mode and individual motorized trips. Secondly, the evaluation of the matching degree of traffic and urban space also shows limitations. The current index focuses on the evaluation of commute aging, but the rationality of land utilization and the matching degree of occupied space are difficult to directly quantify, so that the evaluation cannot effectively support the optimization of urban space structures. In addition, as traffic services evolve towards high quality, existing assessment systems fail to follow in time. For example, it lacks an effective metric for rail transit intelligence level, bus service characterization supply, and a slow-going system humanization design. In terms of economic sustainability, the evaluation system is likewise left blank. In the new stage of turning urban traffic from incremental construction to stock optimization, the existing indexes do not contain direct evaluation items for measuring the benefit or income of operation cost, and the financial health condition of the urban traffic is difficult to judge. Finally, the system has insufficient response to the regional traffic integration strategy. In particular, the specific 123 travel traffic circle targets in the comprehensive traffic planning issued by the city cannot be effectively docked, and specific indexes capable of quantitatively evaluating the realization degree of the remote accessibility targets are lacking. In summary, the existing evaluation work has the defects in the aspects of comprehensiveness and depth of an index system, the evaluation process also depends on manual arrangement analysis, and the problems of low efficiency and insufficient visual result presentation exist. Disclosure of Invention The invention aims to provide a construction method of an urban traffic annual physical examination assessment index system based on multi-source data, which solves the problems that the existing urban traffic assessment method depends on manual arrangement and analysis, has low data processing efficiency, difficult multi-source heterogeneous data fusion, inadequately visual assessment results and difficult traceability and verification of analysis conclusions. In order to achieve the above purpose, the invention is realized by the following technical scheme: The invention provides a construction method of an urban traffic annual physical examination evaluation index system based on multi-source data, which comprises the following steps: The data collection and association step is to collect multi-source data aiming at specific indexes in an evaluation index system, associate the multi-source data with the specific indexes and store the mult
