Travel demand in the urban environment refers to the personal travel or passenger trips generated by economic and/or personal needs. This chapter begins with a brief historical perspective on the evolution of travel demand modeling. Demand for travel is often organized into market segments that reflect a range of factors‐including household income, gender, and age of the traveler; auto ownership; and household structure‐that influence how many and what kinds of travel activities occur. Transportation supply is represented by the roads, transit facilities and services, information technology, and other infrastructure that enable trips to be made. The chapter discusses some of the key principles and concepts that serve as the foundation of demand modeling, and describe the major modeling approaches in use today‐the four‐step model and activity‐based modeling. It discusses the important relationship between travel demand modeling and air quality analysis, and describes different travel demand software packages available to the transportation community.
