Title:

Study of a Strong Wind Warning System

Abstract:

To prevent train derailment due to strong wind, the East Japan Railway Company (JR EAST) issues operating restriction orders in the event of a strong wind. The current operating restriction orders contain some inconsistent points. For example, operating restriction orders are issued after a strong wind has been observed, and they remain in force across the board for 30 minutes after strong wind is not observed any more. To solve this problem, we are currently engaged in developing a strong wind warning system. Using only the time series of the wind velocity data observed on the anemometer installed along the railway tracks, this system predicts the wind velocity about 30 minutes ahead according to the time series analysis technique and issues operating restriction orders. So far we have confirmed the reliability of this system through monitored running and verification of the algorithm using the wind velocity data of meteorological offices.
