Collision damage mitigation method and collision damage mitigation system

摘要

PROBLEM TO BE SOLVED: To estimate magnitude of latent collision risk with high probability as possible, for efficiently reducing collision damage.SOLUTION: A collision occurrence probability and magnitude of damage when collision occurs, considering size and weight of an obstacle on an accident occurrence place, season and time zone, are expressed by a statistic model, based on past accident data for every route, and magnitude of collision risk on a zone where a train is traveling, is estimated, and when the estimated collision risk is high, speed control is performed.
