three zones in your city, as well as these friction factors: ein ve given the following (unbalanced) production and attractions data for the Zone Trip Attracted Trip Produced 1 48,000 63,000 53,000 92,000 3. 2,000 56,000 Total 173,000 211,000 FF 3. 1 1. 1/3 1/4 1/2 1/3 3 1/4 1/2 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.
