The study aims to provide an alternative to ITE TripGeneration Manual (1997) for computing the trip attraction of shopping centers inDelaware. As part of this study, a total of eighteen shopping centers were surveyed, forwhich the number of vehicles entering and leaving the shopping center in every fifteenminutes interval and the number of people visiting each store in the shopping centeralong with their movement patterns were measured.Based on the surveyed data and the aerial photographs, two approaches, microscopic andmacroscopic, are developed to compute the trip attraction rate. The microscopic approachdeals with the relationship between the trip attraction rates of individual stores and theshopping center as a whole. The macroscopic approach relates the trip attraction of theshopping center as a function of the physical features of the shopping center, e.g. totalparking spaces, total floor area, and the number of stores in the shopping center.The study shows that microscopic approach gives a better estimate of trip attractioncompared with the macroscopic approach. The proposed models incorporate the factorsthat have been neglected in ITE Trip Generation Manual. These models should be usefulfor estimating the traffic volume to/from a new shopping center which, is being plannedand to assess the traffic impact of the shopping center on the geometric design ofroadways in the surrounding area.The report consists of the description of the analytical approach, survey methods, the datacollected from the survey and the analysis of the data using the models proposed
