Roadside Equipment Intersection Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intersections pose a high risk for vehicle collisions due to drivers being unaware of approaching vehicles from other directions, and the challenge of accounting for vehicles that disregard speed limits or traffic signals, leading to increased head-on and side impact collisions.
Innovation Solution
A computer-implemented method and system that uses roadside equipment (RSE) to estimate and communicate the path of travel of a reference vehicle, establishing communication with on-board equipment to receive vehicle parameters and environmental data, and determining the probability of collision with a target vehicle, providing collision avoidance warnings and controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drivers rely on traditional visual monitoring at intersections, then they maintain simple vehicle operation, but collision risk increases due to limited awareness of approaching vehicles
Solution Approach 1:
The patent introduces roadside equipment (RSE) as an intermediary system that detects approaching vehicles and communicates their presence to drivers through onboard equipment. The RSE acts as a mediator between the external environment (approaching vehicles) and the driver's awareness, providing information that would otherwise be unavailable through traditional visual monitoring alone.
Solution Approach 2:
The system implements feedback by continuously monitoring vehicle parameters, environmental conditions, and approaching vehicles, then providing real-time collision probability assessments to the driver. This closed-loop feedback mechanism allows drivers to adjust their behavior based on computed risk levels, improving safety while maintaining simple operation.
2Measurement precision
If the system computes collision probability using multiple vehicle parameters and environmental data, then collision detection accuracy improves, but device complexity increases
Solution Approach 1:
The roadside equipment serves as a centralized intermediary that performs complex computations for multiple vehicles simultaneously. By offloading the computational burden from individual onboard systems to the RSE, the patent achieves high measurement precision for collision probability while keeping individual vehicle equipment relatively simple.
Solution Approach 2:
The system merges data from multiple sources (vehicle parameters, environmental sensors, approaching vehicle detections) into a unified collision probability assessment. By combining these diverse data streams through the RSE, the system achieves comprehensive accuracy without requiring each component to be independently complex.
3Reliability
If the system provides real-time collision warnings and autonomous controls, then vehicle safety improves, but ease of operation decreases due to additional driver tasks
Solution Approach 1:
The system implements partial automation by providing collision warnings and probability assessments that assist the driver without requiring full autonomous control. This partial action approach improves safety through automated monitoring while maintaining ease of operation by keeping the driver in control, avoiding the complexity of complete autonomous systems.
Solution Approach 2:
The real-time feedback of collision probability and warnings allows drivers to make informed decisions without requiring complex manual interventions. The system monitors and communicates risk levels continuously, enabling simple reactive adjustments by the driver rather than requiring complex proactive control tasks.

AI summary
A system and method for estimating and communicating a path of travel of a reference vehicle by road side equipment (RSE) that includes establishing communication between the RSE and an on-board equipment of the reference vehicle and receiving vehicle parameters of the reference vehicle from the on-board of the reference vehicle. The system and method also include estimating the path of travel of the reference vehicle based on the vehicle parameters of the reference vehicle and environmental parameters determined by the RSE. The system and method further include establishing communication between the RSE and an on-board equipment of a target vehicle and communicating the estimated path of travel of the reference vehicle from the RSE to the target vehicle, wherein a probability of collision between the reference vehicle and the target vehicle is determined based on the estimated path of travel of the reference vehicle.
