This simulation illustrates a classic example of an intersection collision involving multiple factors. EDSMAC4 simulation was used to establish minimum speeds (actually a speed range). Based on the simulations, it became clear that both drivers contributed to the crash: The driver of the pickup turned in front of an oncoming car that was clearly visible (not to mention that he was towing behind him a 15-ft long trailer!), and the sedan was driven at an excessive speed. Setting the sedan's speed to 35 mph and re-executing the simulation revealed the sedan would have passed about 15 feet behind the trailer (i.e., a near miss, but no collision).
