The creation of a transport system based on the interconnection of n-etworks as diverse as public transport and the road network + private car combination results inevitably in disruptions at the points of connection. These interchanges are often considered nnviable by the user who sees only a forced interruption to his journey. Some remarks are made concerning the technical factors which could contribute to improving the efficiency of these places from the transport (ease of transfer)perspective and concerning practicalities related to transport which could contribute to increas'mg their value. 1 It must not moreover be forgotten that there are interchanges where a significant number of individuals in transit perform tasks, either on the site itself or in the immediate vicinity, other than their principal reason for travel and which have nothing at all to do with transport.
From the perspective of urban life and socio-spatial behaviour, a tendency towards chains of activities - in comparison with carrying them out independently of each other starting from home each time - has been reeognlsed, corresponding to the evolution in ways of life and living arrangements.
We are therefore faced with travel behaviour (in terms of using modes of transport) and individual socio-economic activities which can be represented "via network models, the nodes being respectively the points of connection between the transport modes and the places of activity, and the arcs in both cases being the direct journeys linking the nodes. Accepting that these two "networks" are not independent of each other but are two constituent parts of individual behaviour, the question of their coincidence immediately arises.
