Research conclusions: The result shows the initial traffic volume composition of the Wuhan-Guangzhou Passenger Dedicated Line possesses the characteristics that the induced traffic volume is bigger than the lost traffic volume in the north areas to Yueyang while the lost traffic volume is bigger than the induced traffic volume in south areas to Yueyang. Though the occupancy rate of train is from 36.37% to 80.01% in the different areas, but the completed local railway passenger traffic volume and the utilization rate are low. It is proposed that in this case, the government should regard the high-speed railway as the public welfare undertaking and give the appropriate subsidy to the railway to assist the operator reducing the price of train ticket for enhancing the occupancy rate and giving the play to the high-speed railway, so that the ordinary people can afford and enjoy the efficient travel services of the high-speed railway.
