Road Information Display Timing for Unfamiliar Roads Ahead
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Driving unfamiliar roads or roads with poor visibility can induce stress in drivers due to inadequate information from traffic signs, which do not accurately depict the road ahead, especially in situations like sharp turns or accidents.
Innovation Solution
A road information display system that receives and processes road information from another vehicle, determining an optimal presentation time for displaying this information in the host vehicle, using a receiver, processor, and display to provide detailed road conditions ahead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traffic signs are used to convey road information, then drivers can obtain basic road information, but the information does not accurately depict the road ahead or convey current situation information
Solution Approach 1:
The system creates a virtual copy of the actual road ahead by capturing images with cameras mounted on lead vehicles and transmitting these images to follower vehicles. This copying approach provides accurate visual representation of road conditions, accidents, and traffic situations that traditional signs cannot convey, while maintaining system simplicity through existing communication infrastructure.
Solution Approach 2:
A communication system acts as an intermediary between lead vehicles equipped with cameras and follower vehicles needing road information. This intermediary transmits captured images and processed road information data to multiple receivers, enabling accurate information dissemination without requiring complex display systems in each vehicle.
2Loss of time
If road information is presented early to drivers, then drivers have more time to prepare, but the information may be presented too early to be useful
Solution Approach 1:
The system dynamically adjusts information presentation timing based on the follower vehicle's current position and speed relative to the road section being described. The processor calculates optimal presentation moments to ensure information arrives at the right time - not too early to be forgotten or ignored, and not too late to be useful. This dynamic timing adaptation maximizes driver preparation time while maintaining operational relevance.
3Reliability
If detailed road information is provided about upcoming sections, then driver awareness and safety improve, but driver stress may increase due to excessive information
Solution Approach 1:
The system provides localized, context-specific road information tailored to the follower vehicle's actual route and position. Rather than overwhelming drivers with all possible information, the processor filters and presents only relevant details about upcoming road sections, accidents, or conditions that specifically affect the driver's path. This selective information delivery improves safety awareness while minimizing stress from excessive or irrelevant data.

AI summary
A method of displaying road information in a host vehicle includes receiving with the host vehicle the road information acquired by another vehicle. The road information includes information about a portion of a road ahead of a current portion of the road upon which the host vehicle is traveling. An information presentation time is determined at which the road information is configured to be presented in the host vehicle. The road information is presented in the host vehicle at the determined information presentation time.
