Traffic Light Management System for Abnormal Vehicle Trajectory Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional traffic light management systems fail to effectively alert surrounding vehicles and pedestrians to abnormal vehicle behavior, potentially leading to accidents when an abnormal vehicle is detected within a limited range.
Innovation Solution
A traffic light management system that includes a communication device, control device, and map database, which communicates with vehicles equipped with communication functions to detect abnormal traveling behavior, predicts the vehicle's future trajectory, and sends emergency control signals to traffic lights along that trajectory to temporarily prohibit passage, alerting other vehicles and pedestrians.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If emergency control signals are continuously sent to traffic lights, then the warning effect is improved, but traffic paralysis may occur
Solution Approach 1:
The system sends emergency control signals periodically or intermittently rather than continuously, maintaining warning effectiveness while allowing traffic to flow during non-emergency periods. The control device monitors abnormal traveling information and activates emergency signals only when abnormal vehicles are detected, creating a periodic on-demand warning system that avoids continuous traffic disruption.
2Reliability
If the system alerts all surrounding vehicles and pedestrians to abnormal behavior, then safety is improved, but system complexity increases
Solution Approach 1:
The traffic light management server acts as an intermediary between detected abnormal vehicles and surrounding traffic participants. Instead of requiring direct communication between all vehicles and pedestrians, the server receives abnormal traveling information, processes trajectory predictions, and sends consolidated emergency control signals to relevant traffic lights, simplifying the overall system architecture while maintaining comprehensive safety coverage.
3Reliability
If the system predicts future trajectory and sends signals to multiple intersections, then accident prevention is improved, but communication and processing load increases
Solution Approach 1:
The control device performs preliminary trajectory prediction for abnormally traveling vehicles and pre-identifies future intersections and crosswalks along the predicted path. By calculating future positions and anticipating potential conflict zones in advance, the system can proactively send emergency control signals to multiple traffic lights before the abnormal vehicle reaches them, preventing accidents before they occur while optimizing communication timing to reduce overall load.

AI summary
A traffic light management system that manages display of traffic lights includes a communication device, a control device, and a map database. The control device performs emergency control of the display when abnormal traveling information indicating the information on an abnormally traveling vehicle is included in the information received from a communication vehicle. In the emergency control, the control device predicts a future trajectory of the abnormally traveling vehicle based on the abnormal traveling information. Next, the control device generates the emergency control signal for temporarily prohibiting passage at an intersection and a crosswalk on a road along the future trajectory based on the map information and the future trajectory. After that, the control device sends the emergency control signal to controlled traffic lights. The controlled traffic lights are each a traffic light at the intersection and the crosswalk on a road along the future trajectory.
