| 摘要： | Drivers' last-second braking and last-second steering judgments have been studied extensively by the Crash Avoidance Metrics Partnership (CAMP) Forward Collision Warning (FCW) Requirements project. This previous work was conducted under closed-course conditions using a realistic surrogate target lead vehicle. In the current research, a subset of these tests involving more than 4000 individual test runs has been replicated in the National Advanced Driving Simulator (NADS) facility for comparison purposes. The major conclusions from this research are as follows: scenarios need to pay careful attention to ensure initial headway conditions prior to the critical approach event correspond to those that are typically experienced in real world driving. More generally, scenarios should have real-world validation; scenarios should emphasize high lead vehicle decelerations. The 0.39-g deceleration levels gave the best results and have been used in previous CAMP surprise trial research; scenarios should emphasize cases where the relative speed differential is high, particularly when the lead vehicle is stationary; scenarios should emphasize last-second hard braking or hard steering over last-second 'normal' maneuvers; and crash rates should not be used as a metric, and instead, attention should be focused on the interpretation of last-second maneuver onset behavior. |
