A multilane highway (three lanes in each direction) is on level terrain. The free flow speed has been measured at 50mph. The peak-hour directional volume is 1500 vehicles with 10% heavy vehicles, and PHF is 0.9. If the proportion of vehicles types and peak-hour factor remains constant, how many vehicles can be added to the directional volume before capacity is reached?

A four-lane freeway carries 2,200 vehicles northbound (NB) in the peak hour. The freeway is relatively steep (2 miles of +4.5% grade NB). Free flow speed is measured at 68.2 mph. 15% of the vehicles are heavy trucks and 30% of those heavy trucks are SUT and the other 70% are TT. The PHF is 0.90. Determine ET, fhv, vp, BP, c, S, D, and the Level of Service (LoS)
A multilane highway (two lanes in each direction) is on level terrain. The free-flow speed has been measured at 45 mi/h. The peak-hour directional traffic flow is 1300 vehicles with 8% heavy vehicles. If the peak-hour factor is 0.85, determine the highway’s level of service. Answer: LOS:C
For the Greenshields model, the mean free flow speed on a highway facility lane equals 75 mph near zero density, and the jam density is observed to be about 160 veh/mi. Plot the q-k-u curves in proper order. Write down the speed-density, flow-speed, and flow-density equations. Find out the maximum flow, and also mark it on your diagrams. Compute speeds and densities corresponding to a flow of 2,880 veh/h, describing traffic conditions from a driver’s point of view. Calculate average headways, gaps, clearance, and spacing at CASE 1: maximum flow and at CASE 2: jam density. (Suppose the average vehicle length is 17ft)
A traffic stream is moving at a steady state when entering a mountain grade. Upon entering the grade, the speed, density and flow are 72 km/h, 25 veh/km and 1800 veh/hr respectively. On the grade, a truck drops to a speed of 15 km/h causing traffic to bunch up to a density of 85 veh/km. When the truck pulls over, traffic accelerates to the maximum flow until steady state flow conditions resume. Calculate (a) the flow of traffic behind the truck on the mountain grade (b) the jam density and free flow speed for this road (c) the density and speed when traffic resumes a steady state flow (d) the maximum flow
