Parking Search Index for Traffic Congestion Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems do not effectively provide information on parking lot availability, leading to vehicles searching for parking spaces, which can cause traffic jams and decrease user satisfaction, making it difficult to distinguish and address congestion effectively.
Innovation Solution
An information processing device that calculates and outputs an index representing the distance a vehicle travels in search of a parking lot by comparing the actual traveled distance to a predetermined route distance, allowing for improved guidance and user satisfaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If navigation systems do not provide parking lot availability information, then system complexity is reduced, but vehicles search for parking spaces causing traffic congestion and user dissatisfaction
Solution Approach 1:
The patent introduces an intermediary index (parking search index) that mediates between the navigation system and traffic management. This index quantifies parking search behavior without requiring the navigation system to directly provide parking availability information, thus maintaining system simplicity while enabling traffic flow analysis and improvement
2Loss of information
If vehicles search for parking spaces without guidance, then parking availability information is not required in the navigation system, but user satisfaction decreases and traffic congestion increases
Solution Approach 1:
The patent implements a feedback mechanism by calculating the parking search index based on actual vehicle travel behavior. This index provides indirect feedback about parking search patterns, enabling system improvements and better parking guidance without requiring direct real-time parking availability data in the navigation system
3Productivity
If the navigation system provides real-time parking lot availability information, then user satisfaction and traffic efficiency improve, but system complexity and data processing requirements increase
Solution Approach 1:
The patent creates a simplified copy or representation of parking search behavior through the parking search index, which captures essential patterns without requiring the full complexity of real-time parking availability data collection and processing. This index serves as a manageable proxy for analyzing and improving traffic efficiency

AI summary
An information processing device includes a control unit configured to execute: acquiring a parking point of a vehicle; acquiring a first point that is a point where the vehicle first enters within a first predetermined distance from the parking point; acquiring a first distance actually traveled by the vehicle from the first point to the parking point; acquiring a second distance along a predetermined route from the first point to the parking point; and outputting an index according to the behavior of the vehicle before parking in accordance with a comparison between the first distance and the second distance.
