On an expressway, it was recorded that there is an average of 22 vehicles that are passing the said portion of the highway in every minute. Evaluate the value of the flow of traffic on that day in veh/hr.
Subject : Transportation Engineering Give me right solution according to the question.. Please urgent please Free flow speed of a roadway section is 100 km/h and the capacity of the same section is 3000 veh/h. At a specific point along this roadway section, 2400 vehicles were observed in a predetermined hour. What can be the space-mean speed of these 2400 vehicles if a linear speed-density relationship is considered?
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?
