In this country, personal travel accounts for more than half of total transportation energy use. Thus, a better understanding of personal travel demand allows one to better deliberate solutions to transportation problems. Specifically, policy makers rely on data about personal travel behavior to c the reliability, efficiency, capacity and flexibility of the nation's transportation system to meet current and future demand. Knowledge about personal travel patterns is also important for ing the feasibility and efficiency of alternative ncw congestion-alleviating technologies (eg, high-speed rail magnetically levitated trains),and the air quality impacts and energy security implications of different policies. Economic and socio-demographic changes have contributed to a significant revolution in personal travel behavior, and, have consequently precipitated an unforeseen demand on the current transportation infrastructure. This paper examines how socio-demogaphic changes have affected American's travel patterns, and how changes in personal travel behavior might influence the current capacity and the level of services of our transportation systems.
