To facilitate the development and testing of new active safety systems a new Active Safety Test Area (AstaZero) is currently developed by SP Technical Research Institute of Sweden and Chalmers University of Technology. We have studied different principles for positioning and autonomous control of vehicles, that can be used to monitor and coordinate realistic test scenarios at AstaZero. Furthermore, we have studied how safety critical test scenarios for test and development of active safety systems can be setup based on the uncertainty in measurements. This has been done by simulating a close passing with crossing traffic scenario, which is a test scenario where one vehicle passes just in front of another vehicle. This particular scenario is considered to be one of the more safety critical scenarios and is a typical example of when it is desired to autonomously control the vehicles involved. From simulations we find that that if standard instrumentation is used such a test scenario can be set up with a distance between the vehicles of about 2.97 m tolerating one hit in one billion test. If we instead use state of the art equipment we find that the distance between the vehicles can be decreased to 0.47 m.
