According to ' Monthly report of train accidents and incidents ' of KNR 184 numbers of derailment accidents/incidents had happened during last five years(from 1999 to 2003). Among them, there have happened only four injured accidents such as West Daejeon derailment accident, Jungang line, Pyegje station, and Daejeon station one. But it is necessary to consider a countermeasure for derailment, as its accident/incident have big risk which might produce a large scale damage and lots of injured persons. This paper analyzes the derailment accidents/incidents which have happened for last five years in KNR, and suggests their countermeasures.

This study is a fundamental research to suggest a forecasting model for short-term railway passenger demand focusing on major lines (Gyeungbu, Honam, Jeonla, Janghang, Jungang) of Saemaeul rail and Mugunghwa rail. Also the author tried to verify the potential application of the proposed models. For this study, SARIMA model considering characteristics of seasonal trip is basically used, and daily mean forecasting models are independently constructed depending on weekday/weekend in order to consider characteristics of weekday/weekend trip and a legal holiday trip. Furthermore, intervention events having an impact on using the train such as introduction of new lines or EXPO are reflected in the model to increase reliability of the model. Finally, proposed models are confirmed to have high accuracy and reliability by verifying predictability of models. The proposed models of this research will be expected to utilize for establishing a plan for short-term operation of lines.
