Urban public transportation network optimization method considering subway connection stations

The objective of the invention is to consider bus route optimization of a subway connection route in a functional area. According to the urban public transportation network optimization method considering subway connection stations, functional areas are divided through POI data, comprehensive evaluation indexes are calculated, meanwhile, efficiency evaluation of the metro connection stations is combined, an optimization model is established based on index data, iteration is conducted continuously, and finally a network optimization result is achieved. According to the method, the urban bus passenger flow demand can be coordinated, the public transportation network optimization degree is comprehensively improved and the passenger experience is optimized by adjusting the route direction and prolonging or shortening the passenger flow non-uniform route, and the problems of low bus and subway connection effectiveness, unreasonable route arrangement and the like are solved; the impact on urban public transportatio
