A small town has been divided into three traffic zones. An origin-destination survey was conducted earlier this year and yielded the number of trips between each zone as shown in the table below. Travel times between zones were also determined. Provide a trip dis- tribution calculation using the gravity model for two iterations. Assume K =1. The following table shows the number of productions and attractions in each zone. Zone 2 3 Total Productions Attractions 250 395 450 300 1000 180 425 1000 The survey's results for the zones' travel time in minutes were as follows. Zone 2 3 1 2 1 3 5 8 1 3 The following table shows travel time versus friction factor. Time (min) 3 4 5 7 Friction Factor 82 52 50 41 39 26 20 13 23
