Abstract. Smart transportation in context of the idea of a smart city is an umbrella term for attempts on finding solutions for future mobility challenges in urban areas. This paper gives an overview of current research findings according to the arising challenges. Especially the fields of smart cars, smart traffic controlling by means of sensor-based networks and bike sharing as an alternative way of travel are of special interest here. To give a deeper insight in the named areas, three concrete ideas – one for each of the fields – will be presented in more detail: a solution for the increasing parking space problem for cars, a feasible camera-based sensing network infrastructure and a concept to answer the question of where to create bike sharing spots in an urban environment that meets the actual demand.
