If x, (I = 1, 2, 3) represents the number of vehicles per unit time, the travel times are given by: = 3x; + 5xi — 2 t3 =4+ 4 If 100 vehicles per unit time leave A, determine the optimal division of traffic between the three routes so that a) the overall travel times will be minimized (10%) b) the total disutility in commuter-hours will be minimized (10%) c) Based on the results obtained in a) and b), recommend a policy for improving travel in the borough by briefly explaining the reasons for your choice.
