Architecture of Distributed Traffic Simulation System Based on SOA and Multi-Agents

The architecture of distributed traffic simulation system has much to do with its performance, flexibility and maintainability. To improve the heterogeneity, reusability and interoperability of the system as well as the coordination among different modules, the architecture with four layers is designed based on Service Oriented Architecture (SOA) and multi-agents. New modules are encapsulated into Service Component Architecture (SCA) composites, which not only meet the requirements of heterogeneity and reusability but also facilitate constructions and assemblies of services. Moreover, SOA accessing modules are designed to facilely incorporate existing applications into the SOA system with little modification. With this architecture, the whole system incarnates its superiorities in heterogeneity, reusability and interoperability. Finally, the simulation as an experiment based on a given area demonstrates the validity of the whole system.
