1. A computer implemented method for evaluating autonomous vehicle safety comprising:
defining criteria for safety of autonomous vehicles in a test space, wherein criteria for safety includes a complexity factor based on a number of lanes for a road on the test space;
dividing the test space into an intended test space and an unintended test space, wherein the intended test space includes characterizations for the autonomous vehicle that can be quantified for said criteria for safety, and the unintended test space includes characterizations that are not quantifiable for said criteria for safety;
combining the unintended test space into the intended test space; and
evaluating the intended test space including the feedback from the unintended test space using a combined simulation of the peripheral vehicles and autonomous vehicles using random criteria for vehicle location, vehicle velocity and vehicle route to provide the evaluation of autonomous vehicle safety.
