Study on Organization and Capacity of Waiting-Area for Through Vehicles at Signalized Intersection

In order to improve the capacity of the at-grade intersections, at home and abroad many scholars has taken many effective measures to resolve it. The waiting area for left-turn vehicles has been settled in many cities, the spare area of the intersection isnpsilat made good use to increase the capacity of the intersection. This paper did some work on the traffic organization and capacity of waiting area for through vehicles and the second stop line, at the same time gives the ways of capacity calculation. Both the theory study and practice have proved that the settlement of waiting area for through vehicles can improve the capacity of the signalized intersections greatly, and ensure the pedestrianpsilas safety when they come cross the intersection, So it will have a good prospect of application and extension.
