Question

The optimum speed and the optimum density for the high-speed freeway data set is assumed to be 40 miles per hour and 50 vehicles per mile per lane, respectively. Determine the equations for the Greenberg, Underwood, and Northwestern models, and construct flow-speed-density relationships in a fashion similar to Figure Question 1b.
