Reference no: EM13871110

Question 1: Traffic on an approach of a signalized intersection is travelling at 60 km/h with a density of 50 km/km/In. The duration of the red signals indication for this approach is 30 Sec.

If the saturation flow is 1950veh/h/In with a density of 52 veh/km/In and a jam density is 125veh/km/In, 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

Problem 2: An Australian freeway directional facility 5.5 km in length (Figure Q2) is known to be operating under capacity but the traffic is expected to grow in future. The existing conditions are as follows:

a. The section characteristic are shown in table

b. The acceleration and deceleration rate 100m long

c. Each ramp has one lane

d. The traffic demand profile are shown in table

e. Each time interval is 15 min. and all the demands are expressed as hourly flow rate during each time interval

What is the capacity and level of service profile of the facility under the existing condition?
