According to passenger flow characteristics of its operating through passenger transportation, and combined with other speed object value of airport line in China, this paper puts forward the speed object value program from Xi’an North Station to Airport. The paper also makes comprehensive analysis on the influence of speed object value on track alignment, construction clearance, operation time, operation energy-consumption, distance between stations, system equipment, environmental influence and engineering investment, the program of 100 km/h speed object value is recommended finally for
