Train Door Opening Side Display System for Passenger Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional train guidance displays, undecided door opening-side information causes delays as passengers struggle to move to the correct door in crowded trains, especially when the door opening side is not determined until after departing from the previous station.
Innovation Solution
A train guidance-display system that uses real-time on-rail train information to determine and display the door opening side for all upcoming stops, eliminating undecided information and reducing the need for manual conductor input, by integrating a radio communication system between the train and ground management servers to update door opening-side information in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If door opening-side information is set as undecided for stations where the platform is not decided beforehand, then the system maintains flexibility in handling uncertain platform assignments, but passengers cannot smoothly move to the correct door opening side in crowded trains, causing departure delays
Solution Approach 1:
The system performs preliminary determination of door opening-side information by having the conductor input the information before the train departs from the previous station. This advance preparation ensures that passengers receive accurate door opening side information in time to move to the correct location, eliminating delays caused by undecided information while maintaining operational flexibility through pre-planned platform assignments.
2Measurement precision
If manual conductor input is used to update door opening-side information, then the system can provide accurate real-time information, but the process requires additional manual intervention and time
Solution Approach 1:
The system implements self-service by automatically transmitting door opening-side information from the train information managing apparatus to the display control apparatus without requiring continuous manual intervention. The conductor inputs the information once before departure, and the system automatically updates and displays the information throughout the journey, reducing the time and effort required for information management while maintaining high accuracy.
3Device complexity
If door opening-side information is displayed only for the next stop, then the system keeps the display simple and focused, but passengers in crowded trains do not have sufficient time to move to the door opening side after departing from the previous station
Solution Approach 1:
The system displays door opening-side information for all upcoming stops rather than just the next stop, providing passengers with advance notice of future door opening locations. This allows passengers to plan their movement in advance, particularly important in crowded trains where moving to the correct door takes time. The display shows information for multiple upcoming stops while maintaining clarity and avoiding excessive complexity.

AI summary
To provide a train guidance-display system and a train guidance-display method for enabling the door opening side to be displayed so that it assists passengers in smoothly getting off trains. After latest door opening-side information is received from an operational management server on a ground after a train starts an operation, train-information managing apparatuses output the door opening-side information to display control apparatuses as guidance data, the display control apparatuses create video data indicating an opening side of doors for all stops at least between a next stop and a terminal station of the train using the door opening-side information, and displays perform display using the video data.
