Train Alighting Prediction Using Single-Station Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems require information from all stations to predict train alighting person counts, which is difficult to obtain in complex rail networks and costly to implement, especially for timely congestion management.
Innovation Solution
A train alighting person count prediction system that uses a measurement unit to collect data from a single station, including passer-by counts and train arrival/departure times, to create a prediction model for estimating alighting persons based on train intervals, allowing real-time visualization and prediction of congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If information from all stations is used to predict train alighting person counts, then prediction accuracy is improved, but system complexity and infrastructure cost increase
Solution Approach 1:
The patent divides the prediction system into independent station-level units, where each station predicts its own alighting counts using only local data. This segmentation eliminates the need for complex network-wide data collection while maintaining prediction capability at each individual station.
Solution Approach 2:
The patent extracts and utilizes only the essential data elements needed for prediction (passer-by counts, train arrival/departure times, train intervals) from each station, discarding the requirement for comprehensive data from all stations. This extraction approach simplifies the information requirements while preserving core prediction functionality.
2Measurement precision
If information from all stations is collected, then prediction accuracy is improved, but infrastructure investment increases
Solution Approach 1:
The patent extracts only the minimum necessary data elements (passer-by counts, train timing information) that can be obtained from existing single-station infrastructure, eliminating the need for expensive network-wide data collection systems while maintaining sufficient prediction accuracy.
Solution Approach 2:
The patent employs simple, low-cost measurement approaches at each station using existing infrastructure rather than investing in expensive, complex network-wide systems. The solution uses readily available data from basic sensors and timing devices already present at individual stations.
3Loss of time
If records from all automatic ticket checkers are acquired timely, then real-time prediction is achieved, but operational complexity increases
Solution Approach 1:
The patent implements independent real-time prediction at each station using only locally available data streams, eliminating the need for complex coordinated data collection across multiple stations. Each station operates autonomously in real-time using its own passer-by counts and train timing information.
Solution Approach 2:
Each station performs its own real-time prediction using its own local data, making the system self-sufficient at the station level. This eliminates the need for complex inter-station data sharing and coordination, as each station serves its own prediction needs independently.

AI summary
Provide a technique that can predict the number of persons alighting from a train at the time of arrival of the train only from information obtained within a single station in management of a congestion situation inside a railway station. A train alighting person count prediction device includes: a detection unit constituted by a person count measurement unit that measures a passer-by count in a station and a train departure/arrival detection unit that detects a departure/arrival time of a train; an arithmetic unit constituted by an alighting person count calculation unit that calculates a past train alighting person count from a past passer-by count; a train interval calculation unit that calculates an arrival interval between two trains; a prediction model creation unit that creates a prediction model of a train alighting person count using a train interval; and an alighting person count prediction unit that predicts a train alighting person count using the train interval of the train when the train arrives; a recording unit that records data used in the measurement unit and the arithmetic unit; and an output unit that outputs a prediction result of the train alighting person count.
