Problem 2 A transportation network is shown in the attached figure. Perform traffic assignment for a demand of 3000 vehicles from zone 3 to zone 5 as follows: (1) Find the shortest path between these two zones using the minimum path algorithm discussed in class, and assign 50% of the traffic to the path. (2) Update the travel time for each links with a traffic load by a factor of 1.2 (ie, 20% increase) and assign another 50% of the demand to the next three(3) shortest paths by using the multipath assignment method using travel time as travel impedance. (3) Summarize the link traffic volumes for the network.
