Transport is arguably the single biggest issue for environmental arguments relating to urban form, as reflected by the large number of chapters devoted to this topic. It is claimed that the compact city reduces travel demand, increases the propensity for walking and cycling, and supports public transport. But is this actually the case? Barren investigates the effect of density on travel demand, particularly for work-related travel. Farthing et al. investigate the effect of increased accessibility to local services and facilities on nonwork-related travel behaviour, and Nijkamp and Rienstra analyse the public transport dimension. From this work it is not at all clear that the compact city would yield the advantages it is claimed. The authors tend to agree that local journey lengths may be reduced, but this may not be significant in comparison with the longer trips associated with recreation. They are also united in their belief that a modal shift away from the private car is unlikely.
