A roadway with only one lane in each direction carries traffic of 1200 veh/h at a point where there is a no passing solid line. The density is 20veh/h. A truck carrying a heavy load enters the traffic at 34km/h and this continues for a stretch of 5km before there is a passing lane and the truck can move over to the left hand lane. During this time the vehicle density increased to 80veh/km, decrasing the flow to 900veh/h. Calculate the length of the platoon and the number of vehicles involved.

Concept explainers

Capacity and Level of Service at Intersections

The term capacity is associated with transportation engineering. Capacity helps to understand how many pedestrians or vehicles can be handled by a transport facility. Level of service is also a term associated with transportation engineering. The level of service indicates the performance of the transport facility.

Question

3.2
A roadway with only one lane in each direction carries traffic of 1200 veh/h at a point
where there is a no passing solid line. The density is 20veh/h. A truck carrying a heavy
load enters the traffic at 34km/h and this continues for a stretch of 5km before there is a
passing lane and the truck can move over to the left hand lane. During this time the
vehicle density increased to 80veh/km, decrasing the flow to 900veh/h. Calculate the
length of the platoon and the number of vehicles involved.

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
A four-lane freeway with the following characteristics: ten foot travel lanes lateral obstructions at 0 feet at the roadside total ramp density is 4.5 ramps/mile rolling terrain The roadway has a current peak demand volume of 3500 veh/h. The peak hour factor is 0.95 and there are no trucks, buses, or RVs in the traffic stream because the roadway is classified as a parkway and such vehicles are prohibited. At what level of service will the freeway operate during its peak period of demand?
An existing six-lane divided multilane highway with a field-measure free-flow speed of 45mph serves a peak-hour volume of 4,000 vehicles per hour, with 10% trucks (50% SUT, 50% TT). The PHF is 0.88. The highway has generally rolling terrain. What is the likely level of service for this segment? Good weather, no incidents, no work zones, and regular drivers may be assumed.
A segment of rural freeway is being designed for a FFS of 70 mph through rolling terrain. The directional (i.e. one-way) design volume is 3,000 vehicles per hour. If 10% of the design volume is expected to be heavy vehicles (i.e. trucks and buses), what is the heavy vehicle adjustment used to determine the flow rate? Provide you answer to the nearest hundredths.
