Road patrol quantitative examination system and method based on GPS track positioning

The invention provides a road patrol quantitative examination system and method based on GPS track positioning. The system comprises a vehicle-mounted monitoring equipment group, a vehicle-mounted mobile processing unit, a cloud data analysis system and a GIS map visualization system. And processing GPS data by using a disease identification algorithm module, a GPS data processing correction algorithm library and a GPS positioning service module in the cloud data analysis system. According to the invention, an error correction and cleaning mechanism of GPS track data is utilized, after a large amount of redundant and wrong disease data is eliminated, a disease identification position is transmitted to a maintenance unit to dispose a work order, and the cleaned GPS track data is used to carry out quantitative assessment on a disease patrol process. Quantitative assessment of road patrol is achieved by calculating the road section coverage rate and the section coverage rate, the maintenance conditions of all ro
