경부고속철도 대전/대구도심 선형개량의 표정속도 향상효과 분석

These days, schedule-speed is one of the most important elements of railway industry competence. From the customers" point of view, high schedule speed means that they can arrive their destinations more rapidly. In Korea, Kyeong-bu HSR"s highest speed is 300km/h, yet it"s speed schedule is no more than about 153km/h from Seoul to Busan. In this study, we tried to estimate the effects of Daegu and Daejon track alignment improvement to Seoul-Busan speed schedule using Train Performance Simulation. We found that the two cities" track improvements can raise the speed schedule from 3% to 5% depending on the number of stop stations.
