Question
A small town has residential zones, A and B, producing 900 and 600 work trips respectively. Zone C, D, and E are work opportunity zones attracting 900, 400, and 200 trips. The travel times between the zones and the actual observed trips are as above.
Develop a set of travel time factors (fij) for use in a gravity model that will produce a reasonable approximation of the observed trips. Start with an initial value of fij =1 for all links
Please clearly show your calculations and provide any explanations/assumptions you may have
