Bus route planning and influence factor visual analysis method based on GPS data

The invention relates to a bus route planning and influence factor visual analysis method based on GPS data. The method comprises the steps that firstly, city taxi order data and city interest point data are preprocessed to obtain passenger travel starting place-destination data and POI category data; passenger getting-on and getting-off hotspot grids are extracted, and candidate bus stops are mined based on grid clustering; a bus route planning multi-objective model is further constructed, an optimal bus route set is generated through a multi-objective optimization method, and attribute weight quantification and sorting results are obtained on the basis of statistical route attribute information; and finally, the visual analysis system supports planners to explore and analyze the routes in the optimal route set and supports to change the attribute weights of the routes, the system retrains according to the adjusted attribute weights or subjective sorting to update the sorting result, and an optimal bus route
