Taxis are an important component of urban passenger transport. Research on the daily dispatching of taxis and the utility of governmental management is important for the improvement of passenger travel, taxi driver income and environmental impacts. However, urban taxi management is a complex and dynamic system that is affected by many factors, and positive/negative feedback relationships and nonlinear interactions exist between each subsystem and variable. Therefore, conventional research methods can hardly depict its characteristics comprehensively. To bridge this gap, this paper develops a system dynamics model of urban taxi management, in which the empty-loaded rate and total demand are selected as key factors affecting taxi dispatching, and the impacts of taxi fares on driver income and travel demand are taken into account. After the validation of the model, taxi operations data derived from a prior analysis of origin-destination data of Beijing taxis are used as input for the model to simulate the taxi market in Beijing. Finally, economic and environmental implications are provided for the government to optimise policies on taxi management.
出租车是城市客运的重要组成部分。研究出租车的日常调度和政府管理的效用对于改善乘客出行、出租车司机收入和环境影响非常重要。然而，城市出租车管理是一个复杂而动态的系统，受到许多因素的影响，每个子系统和变量之间存在正/负反馈关系和非线性相互作用。因此，传统的研究方法很难全面描述其特征。为了弥补这一差距，本文建立了一个城市出租车管理的系统动力学模型，其中空载率和总需求被选为影响出租车调度的关键因素，并考虑了出租车票价对司机收入和出行需求的影响。在模型验证之后，使用先前对北京出租车出行起讫点数据进行分析得到的出租车运营数据作为模型的输入，对北京市出租车市场进行了模拟。最后，为政府提供了经济和环境方面的启示，以优化出租车管理政策。
