ABSTRACT
The automobile has been one of the most important products of the 20th century. It has generated an enormous industry and has given individuals a freedom of movement, which has completely changed our ways of living. Indeed, the automobile has been the key factor to a large change in the way our urban societies are structured. The success of the automobile also leads to the saturation of the infrastructures, in particular, in cities. Each car needs a certain amount of space in order to operate. The normal width of roads is 3.5 m in order to accommodate various types of vehicles and steering imprecision. The large development of the car and truck population has also led to critical problems of noise and pollution at the local level as well as greenhouse gas emission at the global level. In order to take into account the problems while preserving the convenience and flexibility of individual vehicles, a solution is being developed.
