Abstract: To properly reflect the interdependency mechanisms between travel behavior, transport networks, and distributions of population, employments, and so on, this study attempts to first establish a new feedback travel demand model and then improve it into an integrated model. With different models estimated based on the same comparatively inadequate and poor quality trip survey data for a developing city, it is confirmed that compared with the sequentially estimated conventional four-step model, the estimation accuracies of both of the proposed models have been steadily improved. For this study, Jabodetabek of Indonesia, one of the representative developing mega-cities, has been selected as the study area. According to the estimation results of the proposed integrated model, some urban and transport development policies are evaluated from the perspective of realizing an environmentally sustainable city. It is found that as the households increase are controlled, new roads were constructed and public transport systems improved, and polycenter development will be a sustainable urban form for the growth of Jabodetabek in the future.
