Abstract:
Trip attraction rates are major inputs needed in traffic impact assessment of commercial
developments. The objectives of this study are to develop models to estimate trip attraction rates for
person trips and vehicle trips and to develop parking standards for three-wheelers, motorcycles,
cars/vans for supermarkets in the Kandy area. The number of vehicles entering and leaving the
supermarkets and the number of people visiting the supermarkets at every fifteen minute interval
during peak hours will be surveyed using a smart-phone based Android application. Multiple linear
regression analysis will be used to analyse data. Central limit theorem will be used to develop parking
standards. For each category a sophisticated model for supermarket designers and simplified model
for local authorities will be developed. The results show that the wine shop area is the governing factor
of the trip attraction rate and parking standards in the Kandy area.
