1. The following data are for the left-turn movement for an approach at a signalized intersection: - Saturation headway, $\mathrm{h}=2\mathrm{s}/\mathrm{veh}$ - Cycle length, $\mathrm{C}=90\mathrm{s}$ - Green time, $\mathrm{G}=60\mathrm{s}$ - Yellow plus all-red time, $Y=3.0\mathrm{s}$ - Start-up lost time, $1_1=2\mathrm{s}$ - Clearance lost time, $1_2=3\mathrm{s}$ What is A. the saturation flow rate (in vph) ( 2 points) Hint: $\mathbf{g}=\mathbf{G}+\mathbf{Y}?{\mathbf{t}}_{\mathbf{L}}{\mathrm{Cap}}_i=S_i\left(\frac{g_i}{c}\right)$ where $g_i=$ effective green time for phase $i(s)$ $\mathrm{G}=$ green time (s) $\mathrm{Y}=$ yellow plus all red time (s) $t_L=$ total lost time (s) ${\mathrm{Cap}}_i=$ Capacity for phase (vphpl) B. the effective green time available ( 3 points) C. if the saturation flow rate is $2,000\mathrm{vph},\mathrm{C}=100\mathrm{s}$, total available green time, $\mathrm{G}=66\mathrm{s}$, yellow plus all-red time, $Y=3.0\mathrm{s}$, clearance lost time, $1_2=3\mathrm{s}$, start-up lost time, $1_1=2\mathrm{s}$, what are i. the effective green time for this movement ( 3 points) ii. the capacity (per lane) for this movement ( 2 points)
