Input flow rate
vph, length of the highway segment L miles and the blocking probability
Pc . This blocking probability should be a small number preferably close
to 0 (e.g. .001) since one wants to minimize the blocking caused by the
congestion in the highway segment so that conditions as close to free flow
traffic occurs. The program iterates until it outputs the optimal number
of lanes N*.
Experiment 2: In this experiment, start out with
a basic highway segment and input flow volume
vph and record the number of lanes necessary. Now let us increase the input
flow volume and record how N* changes to
sudden changes in of a highway segment?
Do this for both the linear and exponential models.
As another variation with this program LESN, vary L instead of and determine how sensitive the lanes are along with the
other performance measures.
