You are given the following (unbalanced) production and attractions data for the three zones in your city, as well as these friction factors: Zone Trip attracted Trip produced 63,000 92,000 56,000 211,000 48,000 53,000 72,000 Total 173,000 2 3 FF 1 3 1/3 1/4 2 1 1 1/3 1 1/2 2 3 1/4 1/2 1 Assume that the trip production is where the trip begins (origin), and trip attraction is where the trip ends (destination). Create the (balanced) OD matrix. Please show the step-by-step calculation. If you present only the final OD matrix, you will receive partial credit.
