AI Technical Summary
Technical Problem
Railroad crossing accidents are prevalent at crossings without safety equipment, and existing systems fail to accurately predict train arrival times during delays, leading to prolonged waiting times for pedestrians and drivers.
Method used
A train approach warning system using mobile terminals and a server device to determine train location and speed, predicting arrival times with high accuracy without requiring expensive infrastructure installations.
Benefits of technology
Reduces waiting times at level crossings by improving train arrival time prediction accuracy using mobile terminals, eliminating the need for costly safety equipment installations.

Abstract
This invention provides a train approach warning system that can reduce waiting times for pedestrians and drivers at railway crossings. [Solution] The system comprises a server device that holds map information and information about the route, a first mobile terminal that acquires train identification information and its own first location information, and a second mobile terminal that acquires its own second location information. If the server device determines, based on the train identification information, that the first mobile terminal is inside a moving train, it predicts the arrival time of the train at the point based on the first location information, the first speed information which is the speed at which the first mobile terminal is moving, and the information about the route. If, at this arrival time, the second mobile terminal is expected to be within a predetermined distance range from the point based on the map information, the server device notifies the second mobile terminal of an alert.
