Question 2. Given the following future travel time matrix (minutes) and future total trip ends, using attraction trip end balancing method (refer to example 2 of course note) to estimate the parameters of a doubly constrained gravity model of the following type and the resulting O-D matrix: Suppose that the best value of B is 0.01 Cost matrix (minutes) 1 10 15 20 100 3 20 17 8 250 D, 450 0 200 650 215 817300 Question 2.
