THE STUDY ON TRIP GENERATION MODEL OF RESIDENTIAL BUILDING IN BANGKOK AREA

There has been blooming development in high density residential building in Bangkok and itssurrounding area. Such residential buildings generate a lot of traffic volume additional to theexisting demand on the road network. This study tries to estimate number of vehicle trip endsdepending on weekday and weekend behavior. Multiple regression analysis with stepwise methodwas applied to develop the relationship between vehicle trip ends and each independent variable. Inweekday behavior, there were four potential independent variables including number of residentialunit (X2), total recreational area (X7), the number of route of directly passing public bus/van (X9),and number of entrance and exit point (X12) in each sample. In contrast, in weekend behavior, therewere five potential independent variables which were X2, unit price (X4), X9, the distance betweeneach sample and main road (X10), and X12. Better estimating trip generation is recommended for areduction of the traffic impact surrounding the residential building. Consequently, more efficientand safer travelling of residents can be achieved.
