Driving test scenarios from real-world driving data is considered as an effective solution for ICV on-road test. The main problem is how to select valid test scenarios from a large number of scenario snapshots. In this paper, a novel test scenario selecting method is proposed. Both the collision risk factor and the traffic factor are considered, and criticality evaluation factors for three typical applications - FCR, LCR and ICR, are defined. A LSTM-AE-Attention model is designed to identify critical scenarios. Experimental results show that the LSTM-AE-Attention based method has rapid convergence and acceptable accuracy while providing critical scenarios is reasonable.
