摘要：	Erroneous decisions by drivers to stop or go at the onset of yellow can lead to incidences of premature stopping or red light running, which in turn can cause severe rear end or right angle collisions. Because trucks or busses are relatively less maneuverable, and also have lower available acceleration rates, lower comfortable deceleration rates, and a higher line of sight than passenger vehicles, the risk of crashes is higher for trucks than other vehicles upon stop or go situations. Dilemma zone protection systems are used at high speed intersections to enhance safety; however, such systems are generally designed around the dilemma zone boundaries of cars, and are static, lacking the intelligence to adapt to existing traffic, weather, or visibility conditions. The current research examined the effect of information systems such as advance warning flashers (AWFs) on the probability of conflict at onset yellow at high-speed intersections. A probit modeling technique was used to establish dilemma zone boundaries. Based on dilemma zone boundaries, probability of perceived conflict curves were computed and compared against actual conflicts that were observed at each of the studied intersections. This information was used to generate a better understanding of the risks associated with the use of AWFs. Results demonstrated that the provision of stop/go information that was consistent with the actual duration of yellow reduced the variability of driver decision making and reduced the dilemma hazard. When no information was provided to drivers, the critical time threshold for stopping was very close to the actual duration of yellow. These findings implied that drivers were inclined to stop when the time to stop bar was greater than the duration of yellow, and were inclined to go when the time to the stop bar was less than the duration of yellow. This concept was used to develop a prototype Yellow Onset Driver Assistance (YODA) system, consisting of a polemounted unit (Stre
