Vehicle Exterior Display Authorization for Road Event Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack efficient and secure methods for vehicles to display real-time information on external displays in response to events on the road, such as accidents, without centralized control and with minimal delay.
Innovation Solution
A decentralized system using blockchain technology and vehicle-to-vehicle communication authorizes vehicles to display messages on external displays based on event detection and sensor data, ensuring secure and timely information dissemination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a decentralized system using blockchain technology and vehicle-to-vehicle communication is implemented, then security and timeliness of information dissemination are improved, but system complexity increases
Solution Approach 1:
The system segments the information dissemination function across multiple independent vehicles rather than relying on a centralized server. Each vehicle independently verifies blockchain transactions and displays information, distributing the computational and decision-making load across the network, which enhances security through decentralization while managing complexity through modular architecture
Solution Approach 2:
The blockchain serves as a trusted intermediary layer between vehicles, providing a decentralized consensus mechanism that enables secure information verification without requiring direct trust between vehicles. This mediator layer handles the complexity of secure communication protocols, allowing individual vehicles to maintain simpler display and verification functions
2Reliability
If real-time event information is displayed on external vehicle displays, then driver safety is improved by guiding drivers around hazards, but privacy concerns worsen due to potential exposure of vehicle data
Solution Approach 1:
The system applies different levels of information disclosure to different vehicles based on their role in the event. Vehicles directly involved in an event receive detailed local information for safety purposes, while other vehicles receive only necessary alert information. This selective information distribution maintains driver safety while minimizing unnecessary privacy exposure for vehicles not directly involved
Solution Approach 2:
The blockchain-based system provides verifiable feedback about the origin and authenticity of displayed information, allowing vehicles to confirm that displayed events are genuine road hazards rather than privacy violations. This feedback mechanism enables drivers to trust the safety-critical information while the selective display protocol protects unrelated vehicle data

AI summary
An example operation includes one or more of determining an event has occurred at a location, responsive to a level of the event being above a threshold, determining vehicles heading toward the location that can display information on an exterior portion of the vehicles, requesting to display the information on the vehicles, and responsive of an approval to the requesting, sending the information to the vehicles to display.
