Driver’s Speed Reduction Behavior at Highway–Rail Intersections

Speed data as a component of driver behavior were measured at two sites where four-quadrant gates are under consideration. Previous research work assumed a constant speed approach for vehicles approaching and crossing a highway–rail intersection with four-quadrant gates. Video data collection techniques were used to statistically test whether vehicle speeds were constant or reduced on approach. The findings were that drivers do reduce their speed on approach to highway–rail intersections, which requires adjusting four-quadrant-gate timing to avoid vehicle entrapment.
