Vehicle Traffic Light Detection System for Driver Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers waiting at traffic lights may not notice signal changes if they do not look forward, leading to potential accidents and interrupted traffic flow due to the need for manual observation of traffic lights.
Innovation Solution
A system and method that uses a camera in a vehicle to capture and detect traffic light information, transmitting it to a mobile terminal or vehicle's interior lighting, allowing for notifications based on communication and monitor states, ensuring drivers are informed of signal changes without needing to look at the light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a driver checks traffic light information manually by looking forward, then the driver can recognize the signal state, but the driver cannot perform other tasks and may interrupt safe driving due to sudden recognition
Solution Approach 1:
The system enables the vehicle to automatically detect and recognize traffic light information through its camera and image processing capabilities, eliminating the need for the driver to manually check the signal state. The vehicle performs the detection task itself and provides the information to the driver through notifications or interior lighting, allowing the driver to focus on safe driving without sudden interruptions.
2Ease of operation
If a driver does not look forward during a stop, then the driver can focus on other tasks, but the driver cannot notice signal changes in time
Solution Approach 1:
The system continuously monitors the traffic light state through the camera and provides real-time feedback to the driver through notifications sent to the mobile terminal or by controlling the vehicle's interior lighting. This feedback mechanism ensures the driver is immediately informed of signal changes even when not looking forward, maintaining both driver convenience and information awareness.
3Loss of information
If conventional warning methods (horn sound or steering wheel vibration) are used to alert drivers of traffic light changes, then the driver can be warned, but safe driving is interrupted due to sudden start
Solution Approach 1:
Instead of using startling warning methods, the system creates a visual copy or representation of the traffic light signal state and transmits it to the driver through the mobile terminal display or vehicle interior lighting. This gentle visual notification method conveys the signal information without causing sudden driver reactions that would interrupt safe driving continuity.

AI summary
A method of providing forward traffic light information during a stop includes capturing a front image in a vehicle, detecting traffic light information from the front image, and outputting a notification corresponding to the traffic light information to a mobile terminal or the vehicle depending on at least one of a communication state with the mobile terminal and a monitor state of the mobile terminal. A system for providing forward traffic light information during a stop includes a mobile terminal, and a vehicle that captures a front image and to detect traffic light information from the front image, where a notification corresponding to the traffic light information is output to the mobile terminal or the vehicle depending on at least one of a communication state with the mobile terminal and a monitor state of the mobile terminal.
