The invention discloses a method of querying real-time bus arrival information, and belongs to the field of intelligent traffic. The method includes utilizing the next station information, station delay and station travelling time information of each bus, and acquiring arrival information of N arriving buses of each line and station in real time and updating and storing; monitoring and receiving query commands, querying the arrival information of the N arriving buses from the cache according to the query commands, and returning the querying result. Defects that current bus querying service only supplies static information are focused, by the aid of dynamic data generated by an existing prediction system, the method, based on internet, of real-time bus arrival information querying service is provided so as to solve the problem that passengers wait for a long time (including waiting in transfer processes) on stations due to low bus punctuality rate, travelling efficiency is improved, and travelling experience is also improved.
