Assuming a linear speed-density relationship. the mean free speed is observed to be 65 mph at near zero density and the corresponding jam density is 160 veh/mi. Assume that the average length of vehicles is 20 feet.
a) Write down the equations for speed-density and flow-density relationships
b) Calculate the speed and density corresponding to a flow of 1000 veh/hr
c) Calculate the average time headway and average space headway when the traffic flow is at maximum value
