Congestion is a characteristic of all heavily used transport systems, and consists of the interference by one traveller in the free movement of another. Although there are well established methods of measuring the cost of congestion, they rely on an unstated subjective element, the 'target' speed considered as reasonable. This is a moving target. At present there is a profound debate among different solutions to congestion, derived from different perceptions of its causes; these alternative solutions include road construction, traffic management, public transport improvements, traffic calming, doing nothing, and road pricing. Apparently there is no consensus on objectives or methods but there is a possibility of a new consensus, based on an integrated approach to all transport systems, a recognition of the impossibility of providing for all potential demand for movement, and an understanding of the importance of human factors and travellers' motivations.
