2. A four zones city has two residential zones A and B, generating 725 and 575 trips, respectively. These trips go to two employment zones C and D, attracting 875 abd 425 trips respectively. The travel time, friction factors, between zones is given as Route AC AD BC BD Travel Time 8 15 10 13 Friction Factors 90 10 60 50 (a) Estimate the trips generating from A and B respectively (b) The OD survey that was performed for this city indicates that the actual number of trips on each route was as follows, AC=650, AD=75, BC-400 and BD = 175. (c) Determine the new friction factor Fij in order the replicate the actual trip movements.
