Test sequence generating method of Cooperative Vehicle Infrastructure System based on support index

System Testing is a key technology of CVIS (Cooperative Vehicle Infrastructure System). A shortest test sequence generating approach in CVIS is proposed in this paper. The paper firstly analyzes the spatial-temporal state of vehicle and complexity of infrastructure in network. Then paper designs system features and test cases, and introduces the concept of support index of the test case to system feature. Then a shortest test sequences generating method and GA method are used to accelerate the convergence speed. The method in this paper provide theoretical basis and implementation guidance in CVIS testing.
