Characteristics of Traffic Flow at Nonsignalized T-Shaped Intersection with U-Turn Movements

open access: yesThe Scientific World Journal, 2013
Most nonsignalized T-shaped intersections permit U-turn movements, which make the traffic conditions of intersection complex. In this paper, a new cellular automaton (CA) model is proposed to characterize the traffic flow at the intersection of this type.
