WebJan 1, 2010 · This paper presents theoretical analysis of left-turn operations under heavy traffic. When traffic demand is heavy, residual queues from previous cycles may occur and contribute to blockage of the left-turn bay by adjacent through traffic. Such blockage reduces the left-turn capacity and is a random phenomenon. An improved model for … WebAT INTERSECTIONS A good place to start is to develop design guidelines for intersections that are responsive to the needs of pedestrians, which can be followed whenever new intersections are built or when existing intersections are being improved or reconstructed. Important intersection issues include consideration of the following: 1.
