Biking and Walking: the Position of Non-Motorized Transport Modes in Transport Systems

Abstract

Long run developments such as income growth and urban sprawl lead one to expect a continuous decline of thecontribution of non-motorised transport modes to the performance of transport systems. In terms of the total number of trips, non-motorised transport modes have retained high shares, however. The potential of non-motorised transport modes to contribute to the urban quality of life is increasingly being recognised. In this paper the possibilities of substitution between non-motorised and motorised transport are discussed. In addition, attention is paid to the issue of complementarity between motorised and non-motorised transport modes.
