TRB’s second Strategic Highway Research Program (SHRP 2) Report S2-S01A-RW-1: Development of Analysis Methods Using Recent Data introduces an approach to microscopic or individual event modeling of crash-related events, where driver actions, initial speeds, and vehicle locations are treated as inputs to a physical model describing vehicle motion.

The report also illustrates how a trajectory model, together with estimates of input variables, can quantify the degree to which a non-crash event could have been a crash event.
