Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of how vehicles navigate intersections in the internet of vehicles system efficiently and safely is not adequately addressed by existing technologies.
Innovation Solution
A traffic flow control method and device that utilize in-vehicle devices to send travel information and intentions to a traffic flow control device, which determines and sends command signals to optimize vehicle movement through intersections based on real-time traffic phase information, lane assignments, and vehicle intentions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles navigate intersections using existing traffic control systems, then basic traffic flow is maintained, but safety and efficiency at intersections are insufficient
Solution Approach 1:
The traffic flow control device receives real-time travel information from in-vehicle devices, processes this feedback data, and dynamically generates command signals to control vehicle movements through intersections, thereby improving both safety and efficiency
Solution Approach 2:
A traffic flow control device is introduced as an intermediary between vehicles and the traffic control system. This mediator receives travel information from vehicles, determines appropriate command signals, and sends control instructions back to vehicles, enabling coordinated and safe intersection passage
2Productivity
If real-time traffic control is implemented at intersections, then vehicle movement efficiency is improved, but system complexity increases
Solution Approach 1:
The traffic flow control device performs multiple functions including receiving travel information from vehicles, determining traffic commands, and sending control signals. This multi-functional approach consolidates complex operations into a single coordinated system, managing complexity while improving efficiency
3Reliability
If vehicles send travel information and receive command signals continuously, then intersection safety is improved, but communication bandwidth consumption increases
Solution Approach 1:
The system implements periodic communication where vehicles send travel information and receive command signals at specific intervals rather than continuously. This periodic action maintains intersection safety through regular updates while reducing overall communication bandwidth consumption compared to continuous transmission

AI summary
A traffic flow control method, a traffic flow control device, an in-vehicle device, and a computer-readable storage medium in the internet of vehicles are disclosed. The traffic flow control method includes: receiving, by a traffic flow control device, traffic control request signaling sent by an in-vehicle device of a first vehicle, where the traffic control request signaling includes travel information of the first vehicle and a travel intention of the first vehicle; determining, by the traffic flow control device, traffic command signaling based on the traffic control request signaling and traffic control phase information of a target intersection, where the target intersection is an intersection through which the first vehicle is to pass; and sending, by the traffic flow control device, the traffic command signaling to the in-vehicle device of the first vehicle. The traffic flow control method, the traffic flow control device, the in-vehicle device, and the computer-readable storage medium in the internet of vehicles can help a vehicle in the internet of vehicles travel safely and efficiently at an intersection.
