过去，大量的研究致力于理解和建模汽车共享服务。然而，一个尚未被调查的研究问题是，在竞争激烈的市场中，拼车公司是如何相互影响的。本文提出了一种基于MATSim框架的研究拼车竞争者相互作用的方法，并利用该方法分析了瑞士苏黎世两家自由浮动拼车公司可能存在的竞争。它还提供了第一次尝试，允许代理人基于离散选择模型做出模式选择决策，该模型包括整个计划层面的拼车备选方案。在拼车模块中添加了重定位功能，允许测试各种重定位算法。本文从两个层面调查了拼车运营商的竞争。第一，通过调查不同价格水平的影响，第二，允许其中一家或两家竞争对手进行搬迁。研究结果表明：(1)在固定的市场费率下，运营商可以通过以0.41瑞士法郎/分钟的价格提供服务来获得最高的利润；(2)提供不同的定价方案可以导致更高的累积回报，尽管其中一个竞争对手的利润会减少；(3)对于承担搬迁负担的公司来说，进行搬迁是无利可图的，而竞争对手可能会享受到搭便车效应，租金增加，利润增加。
A considerable amount of research has been devoted to understanding and modeling carsharing services in the past. However, a research question that has not been investigated yet is how carsharing companies affect each other in a competitive market. This paper presents a methodology, based on the MATSim framework, for investigating the interaction of carsharing competitors and uses it to analyze the possible competition of two free-floating carsharing companies in the city of Zurich, Switzerland. It further provides a first attempt to allow agents to make mode-choice decisions based on a discrete choice model that includes carsharing alternatives on a whole plan level. Relocation capabilities are added to the carsharing module that allow for testing of various relocation algorithms.The paper investigates the competition of carsharing operators on two levels. First, by investigating the impact of different price levels, and second, by allowing one or both of the competitors to perform relocations. The obtained results show that (1) with fixed market rate, operators can obtain the highest profit by offering the service at 0.41 CHF/min, (2) offering different pricing schemes can lead to a higher cumulative payoff, although one of the competitors is left with a reduced profit and (3) performing relocations is unprofitable for the company tasked with the burden of doing it, whilst a competitor may enjoy a free-rider effect with an increasing number of rentals and higher profit.
