The relationship between flow and density on a four-lane highway (two lanes per direction) is known to follow GreenShiled's model, with a free flow speed of 100 km/h and a jam density of 80 veh/km/lane. One of the two lanes of the EB direction will be closed for an entire month for maintenance. The traffic demand for the highway on a typical weekday is shown in the table below. a) What is the maximum length of the queue upstream of the bottleneck during both the morning and afternoon peak hours? b) At what time will the morning and afternoon queues be dissipated? c) Draw the shock wave diagram (for the entire day) showing shock wave speeds, critical times, and distances.

The predicted traffic mix of a proposed four-lane urban non-interstate freeway is as follows. Passenger cars = 78% Single-unit trucks: 2-axle, 5,000 lb/axle = 12% 2-axle, 9,000 lb/axle = 4% 3-axle or more, 23,000 lb/axle = 3% Tractor semitrailers and combinations: 3-axle, 20,000 lb/axle = 3% The projected AADT during the first year of operation is 3,900 (both directions). If the traffic growth rate is estimated at 3 percent and the CBR of the subgrade is 7.5, determine the depth of a full-asphalt pavement (in inches) using the AASHTO method and n = 20 years. The resilient modulus of the asphalt (EAC) is 320,000 lb/in². Assume m, for the subgrade is 1 and the percent of traffic on the design lane is 42 percent, pt = 2.5, and SN = 4. Use a reliability level of 90 percent, a standard deviation of 0.45, and a design serviceability loss of 2.0. Assume the design lane factor f is 0.42. (Use single-axle load equivalency factors for 2-axle vehicles and tandem-axle load equivalency factors for…

An existing rural 4-lane highway is to be replaced by a 6-lane divided expressway (3 lanes in each direction). Traffic volume data on the highway indicate that the AADT (both directions) during the first year of operation is 24,000 with the following vehicle mix and axle loads. Passenger cars = 50 percent 2-axle single-unit trucks (12,000 lb/axle) = 40 percent 3-axle single-unit trucks (16,000 lb/axle) = 10 percent The vehicle mix is expected to remain the same throughout the design life of 20 years, although traffic is expected to grow at a rate of 3.5 percent annually. Using the AASHTO design procedure, determine the minimum depth of concrete pavement required for the design period of 20 years.
13.9. From past records of highway construction and maintenance costs, a state highway de- partment determines the following cost relationships for two-lane bituminous high- ways within the state: c(x) = 0.1.x20 Cm(x) = 3.0-¹ X where the equations hold for (0.5 ≤ x ≤ 10.0) and where x= pavement thickness (inches); c(x)= annualized construction cost (millions of dollars per mile per year); and C(x)= annual maintenance cost (millions of dollars per mile per year). (a) In words, describe the basic tradeoff decision that the highway department must make. (b) Determine the optimal pavement thickness, justifying the type of point found. (c) If pavement thickness can be specified only in whole inches, what is the best pave- ment thickness, considering normal variance in pavement thickness caused by field construction conditions? How sensitive is the optimal cost to small changes in thickness?
