Exploring Sustainable Urban Form of Beijing with an Integrated Model

摘要

To properly reflect the interdependency mechanism between transport networks and trip-making behavior, an integrated travel demand model with feedback mechanism is established for Beijing, a typical developing mega-city. Compared with the conventional sequentially estimated four-step model, it is empirically confirmed that introduction of the feedback mechanism has greatly improved the model estimation accuracy. Moreover, the simulation results suggest that development of transit-oriented urban form with proper control of car ownership and increasing public transit lines would be a promising scenario to realize environmentally sustainable urban growth for Beijing.
