Traffic Sign Assistance Dynamic Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing road sign recognition systems fail to accurately display valid regulation values when a vehicle approaches an intersection, as they do not consider the jurisdictional laws regarding the validity of regulation indicators within a predetermined threshold distance of an intersection.
Innovation Solution
A traffic sign assistance system that uses optical recognition means to obtain data on regulation indicators, sensors to monitor vehicle travel direction, and processing means to determine the location of the next road intersection, measure the distance to the intersection, and maintain or hide the regulation value display based on this distance and direction changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system displays regulation values continuously, then drivers receive consistent information, but the system displays invalid regulation values after intersections
Solution Approach 1:
The system dynamically adjusts the display state of regulation values based on real-time vehicle position relative to intersections. The processing means evaluates whether the vehicle has passed an intersection and updates the display accordingly - maintaining display when approaching intersections and hiding display after passing intersections, making the system adaptive rather than static
Solution Approach 2:
The system uses feedback from GPS location data and intersection database queries to determine whether to maintain or hide regulation value displays. The processing means continuously monitors vehicle position, compares it with known intersection locations, and adjusts display state based on this feedback loop, ensuring accuracy while avoiding incorrect information display
2Reliability
If the system hides regulation values after intersections, then invalid information is avoided, but drivers may lose awareness of ongoing regulations
Solution Approach 1:
The display state is dynamically controlled based on vehicle position relative to intersections. The system transitions between display and hidden states only when the vehicle actually passes an intersection, maintaining regulation awareness continuity while ensuring accuracy by hiding displays only when appropriate
3Reliability
If the system processes intersection data continuously, then regulation validity is accurately determined, but computational resources are consumed
Solution Approach 1:
The system performs intersection validity checks periodically based on significant events such as approaching or passing intersections, rather than continuously processing data at all times. The processing means triggers validation routines when the vehicle enters predetermined distances from intersections or when intersection data becomes available, reducing overall computational energy consumption while maintaining reliable regulation validity determination

AI summary
A traffic sign assistance system for a vehicle including optical recognition unit to obtain data regarding a regulation indicator in proximity to the vehicle, at least one sensor unit configured to monitor a vehicle travel direction, and processing unit. The processing unit are configured to determine a location of a location of a next road intersection based on the vehicle travel direction, measure a distance between a location of the regulation indicator and the location of the next road intersection, cause display of a regulation value associated with the regulation indicator on a display device to be maintained if the distance is less than a predetermined threshold value and a change in vehicle travel direction is detected, and hide the regulation value associated with the regulation indicator from the display device if the distance is greater than the predetermined threshold value and a change in vehicle travel direction is detected.
