Abstract
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.
