Question

By assuming a linear speed-density relationship, the mean free speed on a highway facility lane equals 55 mph near zero density, and the jam density is observed to be about 170 veh/mi.

Write down the speed-density and flow-density equations.
Plot the q-v curves in proper order.
Compute speeds and densities corresponding to a flow of 900 veh/hr, describing traffic conditions from a driver's point of view.

Calculate average headways, gaps, clearance, and spacing at maximum flow and at jam density. Discuss all the results you obtain. Are they realistic?
