Red Light Violator Warning System for Connected Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current red light violator detection systems do not enhance intersection safety by alerting other drivers to impending red light violations.
Innovation Solution
A method and system that uses roadside equipment to detect vehicles about to violate red lights and broadcast warning messages to connected vehicles and devices in proximity, with the option to transmit notification messages to the violating vehicle to take warning actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If red light violator detection systems are used to detect and record violations, then violation detection capability is improved, but intersection safety enhancement is worsened because other drivers are not alerted to impending violations
Solution Approach 1:
The system segments the violator detection function into two parts: (1) detection and recording by traditional systems, and (2) real-time warning broadcasting to connected vehicles. This segmentation allows each system to fulfill its specific function - detection accuracy and safety enhancement - simultaneously.
Solution Approach 2:
The traffic signal controller acts as an intermediary that receives violator detection data and transforms it into warning messages that are broadcast to connected vehicles. This intermediary function bridges the gap between detection systems and safety enhancement by translating detection data into actionable warnings for drivers.
2Reliability
If warning messages are broadcast to all connected vehicles, then intersection safety is improved, but system complexity is worsened
Solution Approach 1:
The traffic signal controller is enhanced to perform multiple functions: traditional traffic signal operation, violator detection coordination, and warning message broadcasting. By making the controller universal, the system avoids adding separate dedicated warning devices, thereby reducing overall system complexity while maintaining safety enhancement capabilities.
Solution Approach 2:
Connected vehicles equip themselves with receivers and warning capabilities, allowing them to autonomously process and display warnings without requiring complex centralized control infrastructure. The vehicles serve themselves by having the necessary hardware and software to receive and act on warning messages independently.
3Reliability
If notification messages are transmitted to the violating vehicle, then the violating driver is alerted, but loss of time is worsened due to additional processing requirements
Solution Approach 1:
The system transmits warnings to other connected vehicles before the violator is detected or before the violator receives notification. This preliminary action allows other drivers to take preventive measures (slow down, prepare to stop) without waiting for the violator notification, eliminating any potential time loss in the overall safety response.
Solution Approach 2:
The system provides immediate feedback to the violating vehicle through notification messages, creating a closed-loop system where the violator receives real-time information about their impending violation. This feedback mechanism allows the driver to correct their behavior instantly without significant time delay.

AI summary
Embodiments include a method for providing a red light violator warning. The method includes detecting that a first vehicle is about to violate a red light at an intersection (302). Based on detecting that the first vehicle is about to violate the red light at the intersection, the method includes broadcasting a warning message to all connected vehicles in proximity of the intersection of a pending red light violation (304) and determining if the first vehicle is a connected vehicle (304). Based on determining that the first vehicle is a connected vehicle, the method further includes transmitting a notification message to the first vehicle warning of a pending red light violation (308).
