A Review on Sustainable Transportation and Circular Economy Actions on Urban Mobility

Recently, the increasing need for energy, water, and material forced the world to seek new solutions by considering sustainability to come through the vicious circle of continuous production and consumption. Therefore, the concept of the circular economy is gaining popularity across the world with its promise of a better future for the next generations. Herein, the cities as the most problematic, highly populated, and industrialized areas are one of the main concerns of the debate. Even though the concept of the circular economy is quite fresh and in the early stages, there are already some actions in cities focused on the green transportation of urban areas. The countries such as China, the European Union, and the USA have already added the circular economy concept for urban mobility to their schedule. The term urban mobility covers all kinds of transportation infrastructure-related problems within the urban areas including congestion, planning, mode share, and optimizations. This paper will review the recent actions in cities based on the circular economy approach from the perspective of urban mobility. Even though there are lots of initiatives for sustainable transportation all around the world, green transportation applications in the frame of the circular economy are highly questionable. Therefore, the aim is to present and unroll achievements on the topic, to give an idea about in-use projects, and to question sustainability.
