This paper introduces a set of Simulation Scene Adjustment Tools which allow users to adjust relevant geo-environmental parameters to create an unlimited number of new scenes that are based on, and share relevant characteristics with, the original. We also introduce a set of novel quantitative metrics that compare the simulation scenes from the perspective of an automated vehicle system. These tools are useful for automated vehicle development and testing to alleviate the problem of having only a few simulation scenes with which to prove out the system.
