Abstract

The invention discloses a method and a device for predicting travel time required between any two points of an expressway and computer equipment. The method comprises the following steps: acquiring the current position, speed and destination position of each vehicle running in a to-be-predicted range on the expressway; judging whether other vehicles exist between the position of the target vehicleand the destination position or not according to the current position of each vehicle; if other vehicles exist, judging whether the speed of each vehicle between the target vehicle and the destination position is smaller than or equal to a first preset threshold value or not according to the speed of each vehicle; if the speed of each vehicle is greater than a first preset threshold value, calculating a first distance between two adjacent vehicles between the target vehicle and the destination position and a second distance between the vehicle closest to the destination position and the destination position according to the current position and the destination position of each vehicle; and calculating travel time required for the target vehicle to arrive at the destination position from the current position according to the first distance, the second distance and the speed of each vehicle.

Description

technical field [0001] The invention relates to the technical field of road traffic information release, in particular to a method, device and system for predicting travel time between any two points on an expressway. Background technique [0002] As the pace of people's work continues to accelerate, the demand for safe, fast, and punctual arrival at the destination continues to grow. In order to meet people's needs, traffic police continue to adopt new technologies to improve the level of intelligent traffic management, and use various methods to predict the arbitrary speed of expressways. The travel time between two points allows people to choose the best route to reach their destination during travel. [0003] Some technical solutions are also disclosed in the prior art to realize the prediction of the required travel time between any two points on the expressway, such as setting a number of video tracking units for continuous tracking of each vehicle driving on the expre...
