Intersection Acceleration Delay Control Against Red-Light Runners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Red-light-running accidents at intersections remain a significant safety concern, with existing solutions failing to effectively prevent vehicles from moving too soon after a traffic signal turns green, especially during poor visibility conditions.
Innovation Solution
An intersection management system that uses processors and memory to detect a vehicle's position at an intersection and delay its acceleration by predetermined periods when the traffic signal is red, preventing the vehicle from being struck by cross-traffic that has run a red light, utilizing environment sensors or geolocation data to determine the vehicle's position and notifying the driver of the delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drivers are given advance warning of traffic signal turning red, then drivers can prepare to stop, but drivers still run red lights frequently due to human error and poor visibility
Solution Approach 1:
The system uses the vehicle's own sensors and processors to detect its position relative to the intersection and automatically control acceleration, making the system self-monitoring and self-regulating without requiring perfect driver judgment
Solution Approach 2:
The system continuously monitors vehicle position, accelerator pedal status, and traffic signal state, then provides real-time feedback by automatically delaying acceleration when safety conditions are not met, creating a closed-loop control system
2Productivity
If vehicles accelerate immediately when traffic signal turns green, then productivity is improved, but vehicles risk being struck by cross-traffic that has run red light
Solution Approach 1:
The system performs preliminary detection of vehicle position and accelerator pedal status before allowing acceleration, and implements preliminary delay action when safety conditions are not fully verified, preventing harmful collisions before they can occur
Solution Approach 2:
The system applies preliminary counter-action by automatically delaying acceleration when the vehicle is in vulnerable positions (first or second position at intersection), counteracting the natural tendency to accelerate immediately and preventing potential collisions with red-light runners
3Reliability
If acceleration is delayed automatically by predetermined periods, then safety is improved, but time loss increases
Solution Approach 1:
The system applies different delay periods based on the vehicle's specific position at the intersection - a first predetermined period for vehicles in the first position and a second predetermined period for vehicles in the second position, optimizing the balance between safety and time loss for each local condition

AI summary
Systems and methods for protecting a vehicle at an intersection are disclosed herein. One embodiment detects that the vehicle is stopped at the intersection at one of a first position and a second position; detects that a driver of the vehicle is pressing on an accelerator pedal of the vehicle; delays acceleration of the vehicle automatically by a first predetermined period, when the vehicle has been detected at the first position; and delays acceleration of the vehicle automatically by a second predetermined period, when the vehicle has been detected at the second position. Delaying acceleration of the vehicle automatically prevents the vehicle from being struck by a cross-traffic vehicle that has proceeded through the intersection against a first traffic signal in a red-light state.
