Autonomous vehicles in the sustainable cities, the beginning of a green adventure

Every revolution promises a spirit of optimism and significant changes. Connected and automated vehicles (CAVs) are coming to our roadways. CAVs have a crucial role to play in the future of transportation. These emerging technologies will provide a safe travel mode by eliminating the human driving error. The CAVs are never distracted or tired. In the last five years, autonomous driving has gone from “may be possible” to “inevitable”. Beyond safer and more enjoyable routes for passengers, the autonomous car also represents a significant step forward in terms of sustainable development. However, many questions remaining under investigations, when will autonomous cars be available? What should be improved first, vehicles or infrastructures? What are the requirements that must be satisfied by Intelligent Transportation Systems (ITS) in smart and sustainable cities? How will these modern technologies impact our transportation systems and the social world? What and how the leading technologies can be used in autonomous cars? What type of sensors and embedded devices to be used? In this paper, we address those issues and to try to provide some suggestions for these technologies that are currently emerging
