Efficiently Testing Intelligent Transportation System in Simulation Environment

This paper presents a simulation test approach to improve the efficiency of testing the Intelligent Transportation Systems (ITS). During the test, the ITS onsite environment is replaced by the simulation environment, which is consisted of two parts: the transport scene simulation model and the sensor simulation model. We firstly extend the transport micro-simulation scene model to support the new behaviors of ITS. Then, the sensor simulation model is linked to the transport scene model as a testing stub which enables to generate test data according to the predefined test strategies. Finally, an ITS simulation test tool is developed and applied for the test automation. The experiment on the real world ITS, i.e. Electronic Toll Collection (ETC) system, demonstrates that the proposed simulation test approach can effectively detect the defects and efficiently test the ITS without deploying any devices.
