What are the best solutions to our transportation and travel challenges? Well, it’s complicated, says Steven Polzin, a research professor in the School of Sustainable Engineering and the Build Environment, part of the Fulton Schools. It requires taking into account multiple factors that shape transportation scenarios, from sociological and environmental perspectives to complex forecasting formulas and planning logistics, says Polzin, deputy director of Teaching Old Models New Tricks, or TOMNET,  which explores and models our mobility choices under various conditions. Here, Polzin examines the popular new concept of induced demand and the outlook for it providing a path forward to more effective transportation planning and management.
