A study of free speed-flow-density relationships at a particular site has resulted in the following calibrated relationship: S=71.2(1-D/ 122)
a) Find the free-flow speed and jam density for this relationship
b) Derive equations depicting the relationship between flow and density, and speed and flow. Plot the resulting curves. Show the values of free-flow speed, jam density, and capactiy on these curves.
c) Determine the capacity of the site mathematically
