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 4 A segment of a 4-lane highway is being designed for a FFS of 60 mph through relatively level terrain. The directional (i.e. one-way) design volume is 1,200 vehicles per hour. If 15% 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.
A section of highway has a linear speed-density relationship. The capacity of the roadway is 3150 veh/hr and this capacity is observed at an average speed of 35 mi/hr. What speed is observed when traffic is uncongested with a flow of 2500 veh/hr? What is the density of traffic when it is congested and operating at 75% of the capacity?
