Four nodes are connected as shown on the figure below: A D A B Assume that links between the nodes are one-way roads. The number of trips between each node is provided in the table below: A 0 450 B 200 0 B C 180 70 C D 340 120 C D 250 500 300 680 = 0 150 The utility functions for car and bus are expressed as: Ucar 5-0.1Tcar Ubus = 20.5T bus 140 0 Assume that travel time on each link is 15 minutes by car and 22 minutes by bus. Please answer the following questions: A. Determine the mode share (percentage of people using car and bus) for each OD pair? B. Develop trip distribution tables for bus ridership and car users? C. Determine the total number of people driving and total number of people taking a bus?
