Dr. Chandra Bhat, a civil engineering professor, along with co-authors Dr. Jessica Guo, a former Ph.D. student, and Rachel Copperman, a current Ph.D. student, received the 2007 Pyke Johnson Award from the Transportation Research Board (TRB) for their outstanding paper in transportation systems planning and the environment. The paper discusses the increasing interdependency of transportation and public health by highlighting the adverse effects of motorized transportation dependency on the environment and public health, and identifies possible benefits of non-motorized transportation, like walking and biking that can increase social equity, improve personal health, and reduce traffic congestion and vehicular emissions. The paper also examines the effects of demographics and urban form on motorized transportation dependency and non-motorized transportation use. Dr. Bhat holds the Adnan Abou-Ayyash Centennial Professorship in Transportation Engineering.
