By assuming a linear speed-density relationship, the mean free flow speed on a highway facility lane equals 65 mph. The jam density is observed to be about 170 vpm. 1. Plot the q-k-u curves 2. Write down the speed-density and flow-density equations 3. Find the maximum flow 4. Compute the speeds and densities corresponding to a flow rate of 1,000 vph, describing the associated traffic conditions. 5. Calculate the average headways and spacing at maximum flow and at jam density. can someone please help me plot the q-k-u curves on paper and solve remainder problems.
