Outline
The safety of automated vehicle running on the real road is related to traffic factors，driver status，and vehicle status. One major challenge faced by automated driving is that the actual traffic environment is characterized by spatial-temporal randomness of road morphology，natural environment，traffic participants and events. And the difference in complexity of testing scenarios results in the irreproducibility of the automated driving testing process and the incompatibility of testing results，which means that the evaluation of automated driving lacks a unified and quantified testing environment benchmark. In this paper，a scenario complexity calculation model for real road test based on operational design condition （ODC） is proposed. Considering the impact of network connectivity，driver perception ability，and vehicle execution ability on the complexity of automated driving vehicles facing relevant scenarios on actual roads，a complexity calculation model element database for autonomous driving actual road testing scenarios based on the eight major categories of road level，traffic facilities，temporary traffic changes，traffic participants，natural environment，network information，driver status and vehicle status. A scenario complexity computational model of real road test based on operational design condition and analytic hierarchy process （AHP） is established，The effect transmission mechanism based on intelligent and connected technology is adopted to calculate the weight coefficient of scenario elements，and the feasibility and rationality of the proposed method are validated in the real road tests.
