Parking Entrance Guidance with Traffic Signal Queue Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking lot guidance systems fail to account for real-time traffic changes, leading to potential congestion at parking lot entrances and inefficient user navigation.
Innovation Solution
An information provision system that acquires traffic light signals and video data to predict queue formation at parking lot entrances, selects alternative entrances based on congestion predictions, and notifies vehicles of the best route to avoid congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the parking lot guidance apparatus decides the entrance gate based on vacancy information only, then the parking lot can efficiently manage vacant parking spaces, but the traffic status changes from time to time are not taken into account and users cannot always reach the entrance gate smoothly
Solution Approach 1:
The system dynamically adjusts entrance gate recommendations by continuously monitoring real-time traffic conditions and queue lengths. The guidance apparatus transitions from static vacancy-based allocation to dynamic traffic-aware routing, allowing the system to adapt to changing traffic patterns and ensure reliable entrance accessibility while maintaining efficient parking space utilization
Solution Approach 2:
The system implements feedback mechanisms by monitoring traffic flow, queue lengths, and entrance gate status in real-time. This feedback loop enables the guidance apparatus to continuously update recommendations, balancing the dual objectives of efficient parking space allocation and reliable entrance accessibility based on current traffic conditions
2Reliability
If the system monitors real-time traffic conditions and queue lengths at each entrance gate, then users can be guided to less congested entrances, but the system complexity increases due to multiple sensors and processing requirements
Solution Approach 1:
The system employs multi-functional camera units that simultaneously capture traffic flow data, queue length information, and entrance gate status. By using a single imaging device for multiple measurement purposes, the system reduces the number of separate sensors and components needed, thereby lowering overall system complexity while maintaining reliable real-time monitoring capabilities
Solution Approach 2:
The system introduces an image processing unit as an intermediary that converts complex visual data from cameras into simplified traffic condition metrics. This intermediary layer processes raw image data to extract meaningful information about queue lengths and traffic flow, reducing the complexity of direct sensor-data processing while enabling reliable real-time monitoring
3Reliability
If the guidance system provides real-time traffic information to user terminals, then users can reach the entrance gate smoothly, but the communication load and information processing requirements increase
Solution Approach 1:
The system extracts only the most critical traffic information (entrance gate recommendations and queue length alerts) for transmission to user terminals, rather than sending complete real-time data streams. This selective extraction reduces communication load and energy consumption while maintaining sufficient navigation reliability for users to reach entrance gates smoothly

AI summary
Signal information acquisition means acquires signal information about a traffic light installed on a road. Video acquisition means acquires a video photographed near a first parking lot entrance facing the road. Prediction means predicts whether or not a queue of waiting vehicles will be formed near the first parking lot entrance based on the video near the first parking lot entrance and the signal information. Selection means selects, from among a plurality of the parking lot entrances including the first parking lot entrance, a parking lot entrance to which a vehicle is to be guided based on a result of the prediction performed by the prediction means. Notification means notifies the vehicle of the parking lot entrance selected by the selection means.
