The location of commercial trip generation hubs produces urban impacts in the area of influence since they increase the number of vehicle trips that affects environment and quality of life. For better understanding of this phenomenon, it is reported in this article an analysis of trip generation rates and models in hypermarkets and supermarkets considering different periods of time and size of the establishments, taking into account USA experiences. After analyzing several editions of the Trip Generation Manual published by ITE (Institute of Transportation Engineers) it is noted that the reported generation rates of vehicle trips decrease with increasing Gross Floor Area (GFA), as the independent variable. This effect is also observed in Shopping Centers models, where the ranges of GFA include those of hypermarkets and supermarkets, allowing to relate these land uses. Finally , the relationship between trip generation and size of the establishment is checked for hypermarkets in Argentina, and generation models of power functions with exponent 2/3 for the independent variable GFA are proposed.
