Abstract
Drivers departing two-way stop-controlled (TWSC) intersections in a straight path typically need to perceive the distance and speed of the approaching vehicles in the cross-traffic stream to select proper gaps that they can utilize for their safe departure. The purpose of this paper is to understand how vehicles accelerate when departing TWSC intersections in a straight path. For this purpose, Global Positioning System (GPS) data logging devices were utilized to record the positions and speeds of departing vehicles. By understanding how drivers accelerate when departing TWSC intersections, we can understand how gap-acceptance decisions are made so that countermeasures may be implemented to reduce the probability of departing drivers accepting improper gaps. Establishing acceleration profiles is also important when analyzing and investigating intersection accidents at a microscopic level to understand how an accident occurred and whether the departing driver was the one at fault (e.g., by selecting an improper gap), or the approaching driver was the one at fault (e.g., by speeding).
