On the Sensitivity of the Gravity Model
Copyright policy )On the Sensitivity of the Gravity Model
The gravity model is perhaps the most widely used mathematical method for predicting travel between subareas in an urban region. In this paper, we will consider the Evans-Kirby version of the model [Transpn. Res., 8 (1974), pp. 105–122]. A formula is derived which shows the sensitivity of the model to errors in data from the prediction year, say ten years in the future, and to errors in data from the base year.
