A traffic signal has a 60-second cycle length (Red time + Green time). For the travel direction
of interest, the red and green times are 30 seconds each, the arrival rate is constant at 20
[veh/min] and the saturation flow (i.e., the departure rate) is 1 [veh/sec].
a. Calculate the average delay (for all vehicles) for the travel direction of interest.
b. Assume a work zone on the street downstream of the intersection so that only 25 [veh/min]
(in the direction of interest) can pass. Calculate the average delay caused by the work zone
to a vehicle leaving the intersection. Assume that the queue at the work zone never backs-
up into the intersection.
c. Discuss qualitatively the implications of queue spillback from the work zone on the delay
of the system.

- Calculate the active earth pressure (exerted by the supported soil mass on the right) against the 10-meter-long, dense and smooth sheet pile wall shown in Figure E2:1. The ground surface is loaded with heavy construction machinery applying a pressure of q = 10.0 kPa. Other data is according to the figure.Assume the sheet pile moves sufficiently to the left to reach active failure conditions behind it, and passive failure conditions develop in the soil mass below the excavation bottom. Draw diagrams for active and passive earth pressure as well as the resultant earth pressure. Questions to Answer: Will the sheet pile wall hold without rain? (Calculate the forces.) Will the sheet pile wall hold if it rains? (Assume water-filled cracks.) If the sheet pile does not hold in any of the above cases – how deep would it need to be embedded in order to hold?arrow_forwardQ.2- Design a flexible pavement by AASHTO method and draw typical cross section of the flexible Pavement for rural highway has following data: - Elastic modulus of Asphalt is 450000 Ib/in², Mr. of base-31000 psi, Mr. of subbase=13500 psi, CBR of base-100 CBR of subbase=22 subbase of subgrade =6 water removed with one week Percentage of time pavement structure is exposed to moisture levels-30% reliability=95% Standard deviation=0.45 initial serviceability=4.2 terminal serviceability=2.5 and ESAL=2*106 subgrade =1500 CBR Mr كلية . المنصور الجامعةarrow_forwardAssume that in earthquake-resistant design, the following relations take place: Y=ce, where Y is the ground motion intensity at the building site, X is the magnitude of an earthquake, and the constant c is related to the distance between the site and center of the earthquake.
