Vehicular Vision System Real-Time Traffic Alerting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle vision systems lack effective real-time traffic condition monitoring and alerting capabilities, particularly in determining traffic jams and accidents, and fail to provide targeted alerts to nearby vehicles or users via communication links.
Innovation Solution
A vehicle vision system utilizing CMOS cameras captures exterior images, processes data to detect traffic conditions, and communicates alerts to a remote server or cloud through V2V or V2I links, providing real-time traffic updates and accident notifications to subscribed users within a specific vicinity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle vision systems use imaging sensors to capture exterior images, then the system can detect objects and traffic conditions, but the system lacks real-time traffic condition monitoring and alerting capabilities
Solution Approach 1:
The system processes captured images through object detection algorithms to identify traffic conditions, accidents, and congestion. Detection results are fed back to generate real-time alerts transmitted via V2V and V2I communication links, creating a closed-loop feedback system that converts static image capture into dynamic traffic information monitoring and alerting
Solution Approach 2:
A remote server acts as an intermediary that receives image data and detection results from equipped vehicles, processes the information centrally, and distributes targeted alerts to nearby vehicles and users. This intermediary architecture enables real-time traffic information sharing across the network without requiring direct peer-to-peer communication between all vehicles
2Adaptability or versatility
If the system communicates alerts to all vehicles, then comprehensive coverage is achieved, but communication efficiency and target precision deteriorate
Solution Approach 1:
The system determines the geographical location of detected traffic conditions and accidents using GPS coordinates. Alerts are then targeted specifically to vehicles within a predefined radius of the incident location, rather than broadcasting to all vehicles in the network. This localizes the alert distribution, ensuring comprehensive coverage of affected areas while minimizing unnecessary communications to distant vehicles
3Loss of information
If the system processes and transmits all detected traffic data, then information completeness is improved, but system complexity and processing burden increase
Solution Approach 1:
The system extracts only critical traffic information from captured images, such as accident detection, severe congestion, and hazardous conditions. Non-critical or redundant data is filtered out before transmission. This extraction approach maintains information completeness for safety-critical events while reducing the overall data processing burden and communication load on the system
Data Source
AI summary
A vehicular vision and alert system includes a camera disposed at a windshield of a vehicle so as to have a field of view forward of the vehicle as the vehicle travels along a traffic lane of a road. As the vehicle travels along the road, the system may determine, via processing by an image processor of image data captured by the camera, traffic traveling along another traffic lane and may generate a traffic alert indicative of the determined traffic. As the vehicle travels along the road, the system may determine, via processing of captured image data, a vehicle accident involving another vehicle and may transmit an accident alert communication to a remote system. As the vehicle travels along the road, the system may determine, via processing of captured image data, a traffic jam index representative of a degree of traffic traveling along the other traffic lane.
