The Statistical Interpretation of Simulated Emergency Breaking Event Time Series Data

Over three hundred four-second / 40hz time series datasets (from simulated emergency braking manoeuvres at English fatal accident sites and field trials) were classified using key characteristics of the braking sequences extracted for each event. These characteristics were then tested for significant difference between road surface types and braking system types. One key marker, average deceleration, was also compared against existing benchmark ‘typical’ values for acceptable performance as found in the literature.
