Abstract:
Transportation planning uses demand estimation models extensively. Models are important because ~)- •
transportation plans and their investments are based on what the models say about future passenger
travel. The bus model was developed to estimate an inter-zonal travel across this transportation
corridor which is required to verify the model accuracy of predictors because it was calibrated using
the data from various surveys done during the years 1996 to 1998. The transportation corridor
includes the Colombo, Dehiwala, Moratuwa, Panadura and Kalutara travel zones. Each zone has
different socio economic, demographic and transport system characteristics with different growth
rates. The bus model therefore captures these characteristics to estimate inter-zonal passenger
demand.
