Intelligent Transportation System for Non-Collaborative Vehicle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The evolution of intelligent transportation systems based on vehicle-to-everything (V2X) communications is hindered by the presence of legacy vehicles that do not support V2X communication, which can lead to increased risks of accidents and reduced traffic efficiency, as these vehicles are 'invisible' to collaborative maneuvers and services.
Innovation Solution
An intelligent transportation system that combines active V2X communication sensors with passive vehicle detection mechanisms, such as video cameras or radar, to identify and report the positions of non-collaborative vehicles, enabling their inclusion in collaborative services and improving safety and efficiency by providing warnings and dynamic maps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If V2X communication is used for intelligent transportation services, then traffic coordination and safety are improved, but legacy vehicles without V2X capability become invisible and cannot participate in collaborative services
Solution Approach 1:
The patent introduces an intermediary system (infrastructure-based detection system with cameras, radar, or other sensors) that acts as a mediator between V2X-equipped vehicles and legacy vehicles. This intermediary detects and tracks legacy vehicles independently and shares their position information with the V2X network, enabling legacy vehicles to be included in collaborative services without requiring V2X communication capability
Solution Approach 2:
The system segments vehicle detection into two independent channels: V2X communication-based detection for modern vehicles and infrastructure-based passive detection for legacy vehicles. This segmentation allows each channel to operate independently according to its capabilities, with the infrastructure system compensating for the absence of V2X signals from legacy vehicles
2Measurement precision
If passive detection mechanisms are added to detect legacy vehicles, then detection accuracy is improved, but system complexity increases
Solution Approach 1:
The infrastructure system is designed with multi-functionality, serving both as a communication node for V2X-equipped vehicles and as a passive detection system for legacy vehicles. The same infrastructure elements (roadside units, traffic management systems) perform dual functions, reducing the need for separate dedicated detection hardware and thereby limiting the increase in system complexity

AI summary
According to a first embodiment of inventive concepts, method of operating an intelligent transportation system may include obtaining first traffic information from a first source, with the first traffic information including position information for a first vehicle, and with the first traffic information being generated independently of the first vehicle. Second traffic information may be obtained from a second source, with the second traffic information omitting position information for the first vehicle. Responsive to comparing the first traffic information and the second traffic information, the first vehicle may be identified as being non-collaborative with respect to the intelligent transportation system. Traffic coordination may be provided based on a position of the first vehicle and based on identifying the first vehicle as being non-collaborative with respect to the intelligent transportation system. Further embodiments may include methods of operating a first vehicle, transport system controllers, terminal devices, and computer program products.
