Measuring Automated Vehicle Safety

Measuring the safety of the operation and behavior of automated vehicles in traffic requires one or more leading indicators, based on non-collision interactions, to produce a quantitative score reflecting the riskiness or safeness of the behavior of vehicles in traffic. Such measurements are critical to the deployment and public acceptance of automated mobility systems. A collision hazard measure with the essential characteristics [1] to provide an effective measurement of safety that will be useful to AV developers, traffic infrastructure developers and managers, regulators, and the public is presented here. This collision hazard measure (SHM) is a kinematic measure that overcomes the limitations of existing measures, and provides an independent leading quantitative measurement of safety.
