Car Congestion Information Generation for Interior Area Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing congestion information systems fail to effectively help passengers avoid crowded vehicles without changing their scheduled car, as they do not provide detailed congestion information specific to the interior areas associated with each boarding door of a target car.
Innovation Solution
An information processing device and method that identify a target car based on a passenger's departure and destination stations, along with time information, and generate congestion information for the interior areas associated with one or multiple boarding doors of that car, allowing passengers to choose less congested areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If congestion information is provided for the entire car, then passengers can understand overall congestion levels, but passengers cannot avoid specific crowded areas without changing cars
Solution Approach 1:
The patent segments the car interior into multiple areas associated with different boarding doors. The congestion information generation unit creates separate congestion level data for each interior area (e.g., first interior area near first boarding door, second interior area near second boarding door). This segmentation allows passengers to see which specific area is congested and choose to board at a different door leading to a less congested area, rather than having to change entire cars.
Solution Approach 2:
The patent applies local quality by providing differentiated congestion information for different interior areas of the same car. Each interior area has its own congestion level based on historical boarding data. Passengers can select a specific interior area with lower congestion by choosing the appropriate boarding door, making the information locally relevant to their boarding choice rather than providing a single average congestion level for the entire car.
2Productivity
If passengers are encouraged to change cars to avoid congestion, then congestion can be reduced, but passengers cannot always change their scheduled vehicles
Solution Approach 1:
The patent segments the boarding process into multiple options (different boarding doors leading to different interior areas). Instead of requiring passengers to change entire cars, the system divides the single car into multiple boardable sections with different congestion levels. This allows passengers to adapt their boarding location without changing their scheduled vehicle, maintaining flexibility while still achieving congestion reduction.
Solution Approach 2:
The patent introduces dynamic choice for passengers by providing real-time or historical congestion information for different interior areas. Passengers can dynamically select which boarding door to use based on current congestion conditions. This dynamic adaptability allows the system to respond to changing congestion patterns without requiring passengers to rigidly change their scheduled vehicles.
3Measurement precision
If congestion information is provided for each interior area, then passengers can choose less congested areas, but the system complexity increases
Solution Approach 1:
The patent segments the car into multiple interior areas, each associated with specific boarding doors. The congestion information generation unit processes historical boarding data to create separate congestion metrics for each segment. This segmentation enables precise measurement of congestion in specific areas rather than providing a single average for the entire car, allowing passengers to make informed decisions about where to board.
Solution Approach 2:
The patent introduces an information processing device as an intermediary that automatically collects historical boarding data, processes it to generate congestion information for different interior areas, and presents this information to passengers. This intermediary handles the complexity of data processing and analysis, keeping the actual measurement and information delivery system relatively simple while still achieving precise congestion measurement for each interior area.

AI summary
An information processing device includes: a car identifying unit identifying a target car that a passenger gets on, in accordance with a departure station and a destination station of the passenger using a car, and with time point information, the car being provided with a plurality of boarding doors; and a congestion information generating unit generating congestion information indicating a degree of congestion of interior areas each associated with one or a plurality of boarding doors of the target car running from the departure station to the destination station.
