This paper developed a driving support system to reduce the driver’s dilemma at signalized intersection. When facing an amber signal phase, the drivers occasionally come across the dilemma whether they should stop or pass the intersection stop line. The proposed system provides the remaining green time (RGT) to the drivers in real-time to support the stop/pass decision making. Driving simulator experiment equipped with the RGT indication system showed that the proposed system significantly reduced the probability of facing the dilemma and encouraged the drivers to decelerate earlier and stop before entering the intersection. Also, logistic regression analysis (LRA) revealed that approaching speed of a vehicle is the most significant factor to affect the stop/pass decision before the amber onset whereas remaining distance and acceleration rate affect it much more after fallen into the amber phase.
