Study on the Capacity of Left-through Shared Lane with Permitted Left-turn Phasing
The capacity of left-through shared lane (here in after referred to as shared lane) with permitted left turn phasing (hereinafer referred to as permitted phasing) is studied in detail in this paper. First, the effect of lef-turn movement on through movement in the shared lane is analyzed comprehensively. Based on probability theory and random service system theory, a quantitative model is developed to estimate the capacity of shared lane with permitted phasing, considering the length factor of lef-turn vehicle waiting area. Based on this model, a volume warrant for lef-turn vehicle waiting area is generated and a method of calculating the optimum length of such area is presented. This study complements the HCM method, highlights the important role of left-turn vehicle waiting area in improving the capacity of the shared lane, and provides a quantitative guideline for traffic design in practice.
