本文件描述了“移动即服务”（MaaS）和“按需移动”（MOD）生态系统中的核心服务、角色和责任模型。该描述基于对参考书目中所列参考文献的文献综述。 本文件还包括对基本服务、角色和责任的比较，以绘制可能用于桥接和合并集成移动中两个主流概念（即MaaS和MOD）的任何相似之处。

This document describes the core services and roles and responsibilities models in the "mobility as a service" (MaaS) and "mobility on demand" (MOD) ecosystems. The description is based on a literature review of the references listed in the Bibliography. This document also includes a comparison of the basic services and roles and responsibilities in order to map any similarities that can potentially be used for bridging and merging the two mainstream concepts in integrated mobility, i.e. MaaS and MOD.
