Vehicle Identification by In-Motion Action Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle identification techniques, such as those described in Patent Literature 1, require vehicles to perform actions of certain durations, leading to prolonged occupancy of spaces and hindering efficient traffic flow.
Innovation Solution
A vehicle identification system that instructs a first vehicle to perform a predetermined action while traveling within a vehicle identification zone, allowing for real-time recognition of the action using sensors, thereby identifying the target vehicle before it reaches a stop position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle identification is performed based on an action performed by a vehicle after stopping, then identification reliability is improved, but traffic efficiency deteriorates due to prolonged occupancy of space
Solution Approach 1:
The system instructs the vehicle to start performing the predetermined action while the vehicle is still traveling in the vehicle identification zone, before the vehicle reaches the stop position. This preliminary action allows the recognition process to begin earlier and potentially complete before the vehicle needs to stop, thus maintaining identification reliability while reducing the time the vehicle occupies the space.
2Measurement precision
If the vehicle continues to stop from start to completion of identification, then identification accuracy is ensured, but time loss increases
Solution Approach 1:
The recognition process is started while the vehicle is traveling in the vehicle identification zone, before the vehicle stops. This allows the identification process to be completed or partially completed during the vehicle's movement, significantly reducing the time the vehicle needs to stop and thereby reducing time loss while maintaining identification accuracy.
Solution Approach 2:
The recognition process continues to operate during the vehicle's movement through the identification zone, rather than requiring the vehicle to stop. This continuous operation ensures that the identification process can complete without interruption, maintaining accuracy while minimizing the duration of vehicle occupancy.

AI summary
A vehicle identification system identifies a target vehicle. First, the vehicle identification system instructs a first vehicle to start performing a predetermined action for identifying the target vehicle while the first vehicle is traveling in a vehicle identification zone. Next, the vehicle identification system starts a recognition process of recognizing an action performed by the first vehicle using a sensor while the first vehicle is travelling in the vehicle identification zone. Then, the vehicle identification system identifies the first vehicle that performs the predetermined action as the target vehicle.
