An estimation of inter-zonal bus demand on Colombo - Kalutara transport corridor

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.
