Abstract
The development of techniques for calibrating the trip distribution models to obtain O-D matrices is well advanced. Therefore, the study of transportation demand should be implemented with distribution of trips in origins and destinations. The first step to study trip distribution is to divide physical space under investigation into mutually exclusive zones or locations. Calibration of the gravity model involves adjusting the friction factor with Newton-Raphson Method. An important consideration in developing the gravity model is "balancing" productions and attractions. Balancing means that the total productions and attractions for a study area are equal. The objective of this paper is to present the pattern of balancing factor in Gravity to achieve convergence with any beta values as input, using Matlab program. It is shown, by way of exponential as friction factor and using Double Constraint Gravity as balancing factor, we could see that the bigger beta value as input, the longer iteration to achieve convergence.
