ITS Information Testing Platform is attempted to design and construct based on its concept to integrate the existing ITS subsystems.Firstly the existing platform development approaches,including process-oriented approach and object-oriented approach,are compared and analyzed.Both of them could not meet the requirements in complex systems development.Then,the High Level Architecture(HLA) in computer modeling and simulation field is introduced and a new logical system architecture development approach based on HLA is brought forward.According to the requirements analysis,the logical architecture of the ITS Information Testing Platform is designed,which comprised of basic data layer,database layer,application layer and user layer.Linking by some interface processes,series of federates cooperated with each other to realize the functions of the platform.In the end,the testing platform is constructed utilizing the existing technologies and equipment.Preliminary results indicated that the platform operated successfully.The platform has integrated on-board navigation system and urban commercial vehicle dispatching system,and it also arranged some interfaces for other ITS subsystems in advance.
