Analysis of Improving Infrastructure of Gyungbu High Speed Railroad to Increase the Schedule Speed

초록

When comparing the result of schedule speed ratio with other counties, the range of schedule speed ratio extends from 66% up to 87.7% based on the maximum speed of 300km/h. On the other hand, the schedule speed of domestic railroad, Gyungbu HSR, from Seoul to Busan, is no more than 153km/h which is the 51% of the highest speed ratio. So, the study is intended to identify what factor would affect the decline of schedule speed by using Train Performance Simulation of train operation pattern and signaling system. According to the result, track alignment improvement would increase the schedule speed form 8.5km/h to 14km/h, and that reduced switching section of signaling system could also raise the schedule speed by about 3.5km/h
