The invention provides a travel guide strategy generation method and device. The method comprises the steps of firstly obtaining a plurality of pieces of historical travel guide information and a monitored vehicle travel track in an affected road segment corresponding to the historical travel guide information; secondly, determining an effective guide rate of the historical travel guide information based on a vehicle driving track; determining a guide strategy of the historical travel guide information; then, based on the guide strategy and the corresponding effective guide rate, training a guide strategy planning model; and finally, determining a guide strategy corresponding to a target blocking event by utilizing the guide strategy planning model. Compared with the prior art, the methodhas the advantages that the guide strategy can be planned by utilizing the real and reliable historical travel guide information, so that the guide strategy output by the guide strategy planning modelbetter conforms to the real guide condition, and the effective guide rate of the travel guide information is further improved.
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...
