The invention discloses a real-time dynamic ship route induction method for a ship in an inland river route network. The method comprises the following steps: collecting information; calculating the real-time dynamic speed of the ship and the interpenetration clearance of the ship; establishing a ship route network weighting topological graph; establishing a generalized path resistance function; establishing an induction path optimization model and solving an optimal route; and outputting a real-time dynamic ship induction route. The real-time dynamic induction route of the ship is calculated by establishing the ship route induction model on the basis of the real-time dynamic ship traffic flow prediction result in combination with the ship route network topological structure in the inland river route network, so that the method has the characteristics of high universality and wide coverage; the LSTM network is adopted to predict the ship navigational speed, the prediction precision is high, convergence is fast, and the workload is small; according to the invention, accurate real-time dynamic induction route information of the ship can be provided, and the reliability is good; due to the fact that the ant colony optimization algorithm of operational research is used for achieving real-time dynamic route planning of the ships in the inland river route network, economical efficiency is good.
