3. (10 pts) The volume at a section of a two-lane highway is 1500 veh/h in each direction and the density is about 25 veh/mi. A large dump truck is loaded with soil from an adjacent construction site joins the traffic stream and travels at a speed of 10 mi/h for a length of 2.5 mi along the upgrade before...

Traffic flow in a highway was 2000 veh/h and the average speed vehicles was 80 km/h. As a result of an accident the ro d is blocked. A queue develops with a density of 275 veh/km. Determ e the rate at which the queue grows in unit of vehicles per hour. (5 markah/marks)

Problem #2 A section of a six-lane highway (3 in each direction) with a two-way-left-turn lane (TWLTL) is being designed. Determine the level of service if the following data are applicable to this section. Traffic Data: • • • Directional design hour volume = 3600 veh/h (all are passenger cars) Peak-Hour-Factor (PHF) = 0.94 Base Free-Flow-Speed (FFS) = 55 mi/h Geometric data: • • • • • Urban setting Rolling terrain Lane width = 11 ft Shoulder width = 4...

please provide detailed soln.
Imagine the situation which a vehicle pulls out onto a single-lane highway that has a flow rate of 400 veh/h (Poisson distributed). The driver of the vehicle does not look for oncoming traffic. Road conditions and vehicle speeds on the highway are such that it takes 2.2 seconds for an oncoming vehicle to stop once the brakes are applied. Assuming a standard driver reaction time of 2.5 seconds, a) what is the probability that the vehicle...

The traffic on a two-way two-lane highway is assumed to follow Greenberg model. The average headway at Capacity is 1.9 seconds while the average spacing at jam conditions is 9 meters. At 9:00 AM on a typical weekday, two platoons were travelling on the highway in the eastbound direction. The length of the first platoon is 3 km and the average vehicle speed in this platoon is 62 km/h. The second platoon is a long platoon that starts directly to...

A multilane highway has four lanes (two lanes in each direction) and a measured free-flow speed of 55 mi/h. One upgrade is 3% and 2 miles long. Trucks are not permitted on the highway, but there are 5% buses in the directional peak hour volume of 1900 vehicles with a peak hour factor of 0.80. What is the calculated density of the highway, assuming familiar drivers are in the traffic stream?
