Abstract: The development of land-use and transportation modeling systems has been experiencing a process that gradually evolves and increasingly improves the functionality of the modeling systems. Following the process, this paper presents a general description of the system structure and the system integration of the various models. The paper also introduces some fundamental ideas and technical factors used to develop land-use and transportation modeling systems, including the two kinds of models (trip-based, and activity-based models), and the three modeling system structures (stand-along, connected, and integrated structures), along with some basic concepts, such as, utility, system equilibrium and dynamic modeling.

Key words: land-use analysis; transportation forecasting; activities; modeling system; system structure
