ABSTRACT
The degradation of the urban environment is greatly caused by the congestion of urban vehicular traffic. Urban environment degradation is the product of a disequilibrium in the functioning of the urban eco-system. Atmospheric contamination, even if the most harmful, as has been said, today goes alongside other emergencies of water pollution and urban waste. Congestion has provoked a situation of paralysis of urban functions to which the reaction has been a search for new spaces for activities and for the reactivation of functions. Information rather than communication has certainly improved thanks to the different technologies of telematics and computing: especially television and the incipient tele-video-communication. The goals of well-being are implicit in any type of evaluation of the state of degradation. And any policy against degradation presupposes some alternative choices of the use of resources and of the means which are simply trade-offs between various goals.
