At Wadi Saqra signalized intersection, the road going to Shmisani has a flow of $1250\mathrm{veh}/\mathrm{h}/\ln$, with a velocity of $60\mathrm{km}/\mathrm{hr}$. The red signal time of this approach is $20\sec$. If the saturation flow is $2000\mathrm{veh}/\mathrm{h}/\ln$ with a density of $70\mathrm{veh}/\ln$, the jam density is $200\mathrm{veh}/\mathrm{km}$, determine the following: a. The length of the queue at the end of the red phase b. The maximum queue length c. The time it takes for the queue to dissipate after the end of the red indication.
