Floating car data quality evaluation and optimization method capable of realizing dynamic adjustment

The invention provides a floating car data quality evaluation and optimization method capable of realizing dynamic adjustment, which is used for solving the technical problem of data abnormity caused by the influence of factors such as road conditions, acquisition time and regional positions in the acquisition process of existing traffic flow data. The method comprises the following steps: establishing a floating car data quality control index evaluation system; obtaining geographic information data of a to-be-measured regional road section and monthly whole sample data of the floating vehicle, and establishing a regional floating vehicle database; calculating data evaluation and correction stage indexes such as sample size, time integrity, space integrity and data reliability according to a sample size, time integrity, space integrity and data reliability index calculation method and a floating car database in a constructed quality control index system; and evaluating and correcting the data step by step by
