Riyadh, the capital of Saudi Arabia, is a city of six million people, dominated by the automobile and laid out in a pattern of centerless, continuous sprawl. However, the city is undergoing a rather miraculous process of transformation, of a kind that is perhaps only possible in Saudi Arabia. A fully developed transport network, comprising 176 kilometers of metro rail and 1,200 kilometers of bus lines, is being laid out over the uniform carpet. This additional layer should manage to break the uniformity of the current city. The unprecedented urban experiment will be a reality in less than two years. Will it help to convert Riyadh in a more sustainable, more livable and more humane city?
