Abstract

The present application provides a method and device for generating a travel guidance strategy. First, obtain multiple historical travel guidance information and the monitored vehicle trajectory in the affected road section corresponding to the historical travel guidance information; secondly, based on the vehicle trajectory, Determine the effective guidance rate of the historical travel guidance information; determine the guidance strategy of the historical travel guidance information; then, based on the guidance strategy and its corresponding effective guidance rate, train the guidance strategy planning model; finally use the guidance strategy planning model, A guidance policy corresponding to the target blocking event is determined. Compared with the prior art, this application can use the real and reliable historical travel guidance information to plan the guidance strategy, so that the guidance strategy output by the guidance strategy planning model is more in line with the real guidance situation, thereby improving the effective guidance rate of the travel guidance information.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for generating travel guidance strategies. Background technique [0002] With the advancement of science and technology, people's economic level is gradually improving. More and more people choose to travel by car, and the number of vehicles on the road is gradually increasing. However, the number of vehicles that each road can carry is limited. Period, or when bad weather, traffic accidents and other conditions occur, it is easy to form a blocking event of traffic jam. The traffic jam not only makes it difficult for vehicles to pass through the location of the blocking event, but also affects the normal operation of the surrounding roads. [0003] At present, in order to prevent vehicles from entering road sections where blocking events occur, the method of publishing travel guidance information is usually used to guide vehicles to choose other ro...
