The invention discloses a heavy-cargo road transportation route optimization method taking road intersection steering into consideration. The method comprises the following steps: step one, constructing a road network data model based on the original road coverage data; step two, constructing a road corner weight auxiliary network based on the road network data model, and applying the weight on the auxiliary side in the road corner weight auxiliary network; step three, generating a network data set based on the road corner weight auxiliary network, setting a target function by considering path intersection steering total weight and path total length, analyzing the network data set by adopting the shortest path analysis method to obtain the optimal path; and step four, by the combination of the corner direction, backstepping the optimal path obtained in the step three into the road network data model, thus obtaining the real optimal path. According to the method, the traffic pressure of a heavy-cargo transportation vehicle on the road intersection can be effectively alleviated, and the integral running time of the heavy-cargo transportation vehicle on the road can be shortened, so that the method conforms to the demands on the complexity of the internal part of the road network.
