The rapid development of economics requires highly efficient and environment-friendly urban transpor-tation systems.Such requirement presents challenges in sustainable urban transportation.The analysis and under-standing of transportation-related behaviors provide one approach to dealing with complicated transportation activities.In this study,the management of traffic systems is divided into four levels with a structural and systematic perspective.Then,several special cases from the perspec-tive of behavior,including purchasing behaviors toward new energy vehicles,choice behaviors toward green travel,and behavioral reactions toward transportation demand management policies,are investigated.Several manage-ment suggestions are proposed for transportation autho-rities to improve sustainable traffic management.
