Embodiment Construction

[0036] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0037] The inventive concept of the present invention is to provide a real-time prediction method for vehicle travel time on urban arterial roads under the background of Internet of Vehicles, so as to realize accurate real-time prediction of the travel time of any vehicle on urban arterial roads. In the context of Internet of Vehicles, vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) realize real-time data interaction between vehicles and the environment through the wireless Internet. This technology not only enables vehicles to interact with each other, but also interacts with surrounding infrastructure such as traffic lights and road signs within a range of 2,000 meters. For example, the current signal phase and duration can be sent to the driver.

[0038] for figure 1 In the urban arterial road section to be studied, all the vehicles ar...

Abstract

The invention discloses an urban trunk road vehicle travel time real-time prediction method based on Internet of vehicles, belonging to the technical field of intelligent traffic. The method comprises the steps of (1) obtaining the queue cumulative shock wave velocity and queue dissipation shock wave velocity of a road to be researched in a previous signal control cycle, and calculating the maximum queuing length of vehicles and the queuing length in maximum queuing delay of the road to be researched in a current signal control cycle, (2) with the red lamp end time of a previous signal control cycle of the road to be researched as a time origin, determining the four critical time points of the current signal control cycle, and (3) calculating the travel time prediction value of a vehicle to be researched at the road to be researched according to the time period determined by the time point that the vehicle to be researched enters into the road to be researched and the four critical time points. According to the method, the accurate and real-time prediction of the travel time of any vehicle in an urban trunk can be realized.

Description

technical field [0001] The invention relates to a method for real-time prediction of travel time of vehicles on urban arterial roads based on Internet of Vehicles, and belongs to the technical field of intelligent transportation. Background technique [0002] Vehicle travel time prediction on urban arterial roads has always been a difficult problem in the field of traffic management and control, especially for real-time prediction of road travel time for a single vehicle, and it is difficult to obtain personalized real-time travel time. Previous travel time predictions were mostly based on historical data collected by detectors to obtain the average travel time of all vehicles over a period of time, which lacked real-time and pertinence. Compared with the average travel time, the real-time prediction of a single vehicle’s travel time is more important for travelers. Said to be more valuable. [0003] With the increasingly severe urban road traffic problems, the Internet of ...
