E-Bike City: Designing sustainable streets

Transport policy in cities is facing urgent and wicked challenges. On one hand, traffic must quickly decarbonize and reduce its negative externalities such as noise, pollution, and accidents. On the other hand, rapid population growth in cities, together with economic growth, and urban sprawl drive an ever-growing demand for car travel on already congested roads. Further demand is induced by infrastructure extensions aimed at reducing travel times, creating more sources of emissions and negative externalities. And finally, migration, liberalization of social norms, as well as other changes in the society create a growing diversity of groups with distinct activities and needs. As a result, in addition to reducing its carbon emissions and negative externalities, transport in cities must also provide enough capacity for growing urban populations and address the complex issue of social equity.
