Analysis Of Demand For Sunset-departure And Sunrise-arrival Trains On High-speed Railways Based On Generalized Cost

With the development of economy and the progress of science and technology,people have more and more time requirements,high-speed railway came into being.Considering the long distance travel and people's convenience and comfort,the State Railway Bureau launched Sunset-departure and Sunrise-arrival Trains(SST)on High-speed Railways(HSR).SST on HSR runs at night,does not affect the normal working hours of passengers,once introduced it received people's welcome.This paper studies the best travel range and the suitable crowd of SST on HSR in the range of 1 500~3 000 km,and compares the SST on HSR,train of daytime on HSR and airplane.This paper firstly combs and summarizes the research situation of domestic and foreign literature on passenger travel demand of SST on HSR,and then analyzes the factors affecting the demand for passenger travel,including the characteristics of passenger travel and the characteristics of passengers during the trip,and transform economy,fastness and comfort into quantitative mathematical model,and the characteristics of economy include the passenger's age,health status and travel time distribution in a day.This paper analyzes the demand of SST on HSR from three aspects which are fare,travel time and fatigue recovery.This paper first calculates the fare rate of five modes of transportation,and then gives the calculation model of the fare.Then according to the relationship between travel time and travel distance,the travel time calculation model is obtained.Finally,according to age,health status and travel time in one day distribution to calculate the fatigue recovery time,and travel time and fatigue recovery time into cost,finally studies the general cost of the passengers of different income levels from the perspective of time value.This paper analyzes market of SST on HSR in the travel range of 1 500~3 000 km,puts the data of travel distance,age and income into the generalized cost model,and compares the generalized cost of five kinds of passenger transport products in the different travel range,then gets the suitable distance range and crowd of SST on HSR.
