SKAB / SKAA 3842 - 3- Q2. (a) Table Q2 below gives the flow and saturation flow for all approaches (in pcu/hr) at unsignalised junction in Kluang district. The influence of heavy vehicles, turning movements and all other factors have already been considered. All approaches consist of one exclusive right turn lane (RT), one straight-through traffic (ST) and one straight- through shared with left turn (STLT).
