中文摘要：
将RGPS元建模框架应用到城市交通领域的需求建模中,通过为出行者提供出行规划的需求用例来说明,RGPS能够为服务资源提供有效的聚合机制,促进服务资源间的协同,并充分考虑到情境因素对需求建模的影响,最终通过规模化定制来完成城市交通信息系统的构造以最大程度地满足用户需求。
英文摘要：
Requirements in urban transportation is increasing gradually and transportation network is becoming more complicated,which lead to the fact that the complexity of requirements modeling in urban transportation domain leaps accordingly.Meanwhile,how to aggregate existing service resources in an effective way and construct urban transportation information systems to satisfy personalized requirements become key issues faced by requirements modeling.Towards these problems,a context-aware and service-oriented requirements meta-modeling framework named RGPS is proposed in this paper by introducing corresponding contextual elements into the original meta-models.Then,a typical requirements use-case in urban transportation domain,providing trip plan for travelers,is demonstrated in detail to show how RGPS can support requirements modeling in application domain.
