The need to remedy and enhance the urban fabric and the built environment by reducing its harmful effects and creating good, functional, healthy living conditions, is not new; it is even mentioned in Bible texts (Deuteronomy XXIII, 12-13), where along with several requirements of hygiene, issue related to aesthetic upgrade are raised as well. This need is also pointed out by Professor G.P. Lavvas in his book “Topics of Cultural Management“, a need that is becoming only more pressing, as the consequences of climate change and the harmful anthropogenic impact on the environment escalate and need to be addressed urgently.
Creative solutions to these problems are being proposed by architects and engineers around the world, are initially tested on a small scale and are expected to be gradually adopted to a larger extent. One such effort, and an excellent example of a sustainable city, is Copenhagen; which aims to be carbon-neutral by 2025 and there are already five times more bicycles than cars on its roads.
Road networks and transport are indeed a particularly important part of urban planning and infrastructure. It is generally accepted that the cities in which one wishes to live or at least visit are primarily cities in which one can move comfortably on foot. Urban planning that facilitates walking, in combination with good public transport and bicycle route networks, will help to reduce cars, traffic congestion and exhaust fumes in the centers of large cities, and therefore to their overall aesthetic and functional upgrade.
