road does not stop. Using the AASHTO method, determine the required sight distance along the major road for
left-turn movements for the following scenarios:
combination-truck, 2-lane major road (undivided)
Single unit truck, 3-lane major road (one lane in each direction with a 12 ft. center two-way left turn lane)
Passenger car, 4-lane major road divided by an 12 ft. median.

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
True or False: Directional and lane distribution factors need to be considered to obtain initial traffic on the design lane.

Design speed of a six-lane undivided highway is 70 mph. A circular section of the highway has level grade, 10-ft wide lane, and the radius of the highway centerline is 1000 ft. Calculate the minimum side clearance required from the edge of the innermost lane on the highway to provide adequate sight distance for safe travel
A 4-lane divided highway has a highway grade of -1.5%. The minor road approach grade is 3.5%. The design speed is 45 mph for the major road and 40 mph for the minor road. Find the left turn departure sight distance for a passenger car turning left from the minor road to the major road, The answer should be in feet.
