Harbor road longitudinal gradient design method based on cellular automaton

The invention relates to a harbor road longitudinal gradient design method based on a cellular automaton, belonging to the technical field of harbor road design and comprising the following steps of: preliminarily determining a higher limit span of a longitudinal gradient to be designed; obtaining the running property of a harbor vehicle from the dynamic performance of the vehicle, the natural environment and the psychological characteristics of a driver; establishing a cellular automaton simulation model to determine the following rules of a harbor vehicle longitudinal slope running simulation model based on the cellular automaton: simplifying the vehicle type of the harbor vehicle, and carrying out conversion on various vehicles into a single vehicle type, establishing a cellular automaton simulation model to simulate the harbor traffic through controlling the longitudinal gradient value parameter, and evaluating the result to inspect whether a design scheme reaches the demand of the traffic capacity or not
