Vehicle travel time prediction method and device and computer device

Abstract

The invention relates to a vehicle travel time prediction method and device and a computer device. The vehicle travel time prediction method e comprises the following steps: acquiring time informationand position information of target vehicle driving, determining time slice information of a target vehicle according to the time information, determining spatial slice information of the target vehicle according to the position information, when it is determined that the target vehicle is located in a target space slice according to the position information, according to the position information,the time slice information and the historical time information, calculating a time feature vector of the target vehicle; according to the spatial slice information and the reference speed in the spatial slice, calculating a spatial feature vector of the target vehicle; according to the time information, the position information, the time feature vector and the space feature vector, predicting thetravel time of the target vehicle. The problem that the prediction accuracy is low under the condition of carrying out long-term prediction on a vehicle in a public transport system based on a spacefeature vector is solved, and the prediction accuracy of the travel time of the vehicle is improved.

Description

technical field [0001] The present application relates to the technical field of public transportation, in particular to a method, device and computer device for vehicle travel time prediction. Background technique [0002] The urban public transportation system can greatly relieve traffic congestion and effectively alleviate environmental pressure in terms of energy consumption, and is the best choice to solve urban traffic problems. Among them, urban bus travel time prediction is one of the key technologies to improve travel structure, improve bus service reliability, and alleviate traffic problems. However, the urban public transportation system is a highly uncertain, nonlinear multi-parameter involved, time-varying complex giant system, and its travel time prediction is more complicated, especially in the short-term prediction of less than 15 minutes, the occurrence of accidental events The probability is greater, time-varying, and uncertain, and the prediction accuracy...
