Close following on highway can often be dangerous and lead to safety-critical situations. The escalation of criticality may vary depending on several operating factors, including roadway conditions, braking capabilities, visibility, and drivers’ reaction time. We analyzed nearly 2 million miles of naturalistic truck data to study truck driver following behavior. Truck drivers were seen to typically follow other vehicles with a headway of less than 2 s, which is equivalent to 50 m if the truck is traveling at a speed of 55 mph. Such small following distance may be dangerous during an unexpected events. Hence, we used formal methods to simulate such unexpected “what-if” situations by varying parameters from driving scenarios and analyze safety from a theoretical point of view, referred to as Responsibility-Sensitive Safety (RSS). Our simulation shows that interstate driving scenarios often violates RSS safety conditions and may lead to safety-critical events.
