Switching method and device of bus code, mobile terminal and readable storage medium

The embodiment of the invention discloses the switching method of a bus code. The method is characterized by collecting the position information and the WiFi information of a mobile terminal when thewake-up operation of the bus code is detected; if the position information and the WiFi information are collected, searching a bus site set matching with the WiFi information from the mapping databaseof the bus sites and WiFi; then, searching the matched bus site from the bus site set; and finally, using the type of the matched bus site to switch the bus code. The bus site is matched with the WIFI to realize accurate identification from the mobile terminal to the bus site. The bus code is automatically switched under the condition that the bus site is accurately identified, and the probability of manually switching the bus code is reduced. Under the condition that the WiFi information of the mobile terminal is not collected, the type of the matched bus site of the mobile terminal is predicted by using a riding preference model, and the accuracy of prediction is improved. And then, the bus code is switched through using the type of the matched bus site so as to reduce the probability of manually switching the bus code.
