Abstract

The invention discloses a traffic guidance statistical model proofreading method and device. The method includes: building a model prediction module based on a preset traffic guidance statistical model; acquiring the measured road section information of a vehicle, the measured road section information including the identification information of the vehicle, Input the travel time information in the measured road section information to the model prediction module for the selection information of the route and the travel time information, and obtain the model prediction value; according to the model prediction value and the measured road section information, construct a Bayesian Calibrate the model to get the corrected predicted value. The implementation of the invention can improve the prediction accuracy of the traffic guidance model.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and device for correcting a traffic guidance statistical model. Background technique [0002] Traffic guidance relies on technologies such as electronics, computers, networks, and mobile communications to provide travelers with optimal route guidance instructions according to their starting point and destination, or to help road users find a route from the starting point to the destination by obtaining real-time traffic information. The optimal path to the ground, and then pass the information to the pedestrians through the inductive LED screen. The information accuracy rate of the traffic guidance system is often very high, but private car drivers in different cities have different behavior inertia, which is also reflected in the different degrees of compliance with the traffic guidance. Taking Washington DC or Los Angeles as an example, most travele...
