    摘要:

    公共交通的发车频率是体现公共交通供给和服务水平的重要指标.在考虑容积率对广义成本影响的基础上,建立了一个新的基于广义成本的公共交通模型.分别以"社会福利最大化"和"企业利润最大化"为目标,从最优定价的角度构造了2种公共交通最优发车频率模型.研究表明,在不考虑外部性效应的情况下,该2种公共交通最优发车频率是相同的.最后根据某市的广义成本参数估计值,利用该模型对发车频率进行了模拟,表明此模型可行.

    Abstract:

    The service frequency is an important factor which shows the supply and service level of public transportion. By considering the effect of occupancy rate on generalised cost firstly, the authors establish a new public transport model based on generalised cost. Then from the view of optimal pricing, this paper constructs two optimal service frequency models by the aim of maximizing social welfare and maximizing profit separately. The result shows that, without the effect of externalities, the two optimal service frequency is the same. Finally, this paper use some parameters of generalised cost, which coming from a city, to simulate this model, and the result shows it is feasible.
