INFLUENCE OF LEADING VEHICLE TURN SIGNAL USE ON FOLLOWING VEHICLE LANE CHOICE AT SIGNALIZED INTERSECTIONS

The findings of a phenomenological study of a rarely addressed subject are discussed: the degree to which turn signals are properly used at signalized intersections and the effect that nonuse has on the land-choice behavior of subsequent through vehicles. The situation studied involved a lane drop at the far side of the intersection. Three experiments were conducted at two locations to observe the lane preferences of isolated subject vehicles and three cases of car-following. The study revealed that a considerable proportion of left turners failed to properly indicate their movement intentions and this had a significant effect on following through vehicles. Lane choice was also found to be affected by the distance to the lane drop and by the traffic signal display. On the basis of these findings additional study of this subject is recommended. (Author)
