动态共乘（DR）作为一种缓解城市交通出行难题的新模式目前并没达到预期效果，而解决途径需要从接受意愿和运行过程来考虑。本项目从如何开展DR服务入手，拟对DR服务的四个基本问题展开研究。（1）DR服务接受意愿：主要研究不同信任水平下使用DR服务的风险和收益怎样决定潜在参与者服务接受意愿，以及建立怎样的信任机制；（2）DR匹配服务：主要研究三个问题，一是DR成功匹配的标准怎样确定，二是如何建立DR特征匹配模型，并在多智能体平台上实现；三是如何快速实现乘客与司机的多对多匹配；（3）DR信息服务：评价DR信息服务能力，确定关键因素，分析社会媒体创新能力的影响，建立虚假信息识别模型，提高信息质量；（4）DR服务价值：根据所构建的DR服务社会福利函数，分析外部收益和服务费用替代方式，寻找车主参与的激励机制。项目研究所针对的问题在国际上也刚起步，研究成果有限。所设计研究内容有新意，研究前景具有实际意义。

Dynamic Ridesharing (DR) as a new approach to alleviate the problem of urban travel does not achieve the desired results, while address ways should be considered from the willingness to accept and operating process. The project, starting from how to carry out the DR Service, does research from the following four basic questions concerning DR Services. (1) Willingness to accept DR Services: the main study focuses on the security / potential risks and benefits of DR Services under different trust levels, how to determine the participants' willingness to accept DR Service, and how to build trust mechanism; (2) DR matching service: The main study focuses on three aspects. Firstly, how to determine the successful matching standard of DR; Secondly, how to build the Characteristics Matching Model and realize the matching model in multi-agent simulation platform; Thirdly, how to achieve fast matching under circumstances of many-to-many passengers to drivers; (3) DR information services: To evaluate DR information service capacity to screen key factors, to analyze impacts of social media innovation capability, and to create recognition model to identify fake information, thus to improve information quality; (4) DR Service value: According social welfare function, to analyze external revenue and service cost alternatives, to look for incentive mechanism of participants. The project is just for international start-ups with limited research. Designed new study contents are promising and have real significance in practice.
