abstract="Knowledge of pedestrian travel behavior is very important to attempts to improve congestion problems in central business districts. This paper describes the results of the use of a traditional gravity model for predicting pedestrian trip distribution. The model is calibrated by using a data set from downtown Chicago. The results indicate that the traditional gravity model closely reproduces the characteristics of pedestrian trip distribution and might be a useful tool in the analysis of downtown travel.<p />",
