摘　　要：城际客运市场中的多种交通工具存在竞争关系,城际轨道交通票价高低直接影响通道内各交通工具客流分配大小,也就是票价需求弹性关系。为了明确这一关系,通过确定城际旅客出行选择影响因素构建出行选择函数,在通道总客流守恒的条件下,构造基于票价需求弹性的均衡配流模型。通过西安北客站至机场城际通道内的调查及运营数据,应用该模型计算在通道总客流守恒的条件下该城际通道内各交通工具自身及相互间的票价需求弹性值,并将城际轨道交通票价设置为变量,测算在票价变化下通道内各交通工具客流量及弹性值的变化规律,结果符合实际情况,验证了算法的有效性和合理性。There is competition among various means of transport in intercity passenger transport market.The ticket price of intercity rail transit directly affects the passenger flow distribution of various means transportation in the corridor,i.e.,the elasticity of ticket price.To clarify this relationship,this paper constructs a travel choice function by determining the influencing factors of intercity passenger travel choice,and under the condition of conservation of the total passenger flow in the channel,a balanced allocation model based on the elasticity of ticket price demand is constructed.Based on the survey and operation data of the intercity channel between Xi’an North Passenger Station and the airport,the model is used to calculate the elastic value of ticket demand of each vehicle in the intercity channel itself and among these transportation methods under the condition of the conservation of the total passenger flow of the channel,and the ticket price of intercity rail transit is used as a variable to calculate the changing law of the passenger flow and elastic value of each vehicle in the channel under the change of the ticket price.The results are in line with the actual situation.The validity and rationality of the algorithm are verified.
