Megacities have frequently received a disproportionate amount of attention over other sizes of cities in recent discourse on urban sustainability. In this article, the authors argue that a focus on smaller and medium-sized cities is crucial to achieving substantial progress towards more sustainable urban development, not only because they are home to at least a quarter of the world’s population but because they also offer great potential for sustainable transformations. In principle, their size allows for flexibility in terms of urban expansion, adoption of “green” travel modes, and environmental protection. At the same time, smaller and medium-sized cities often have fewer resources to implement new transport measures and can be more vulnerable to fluctuations in the world economy. This article critically reviews the potential role and impact of nine commonly considered options for sustainable urban transport in cities in developing countries: (1) road infrastructure; (2) rail-based public transport; (3) road-based public transport; (4) support for non-motorized travel modes; (5) technological solutions; (6) awareness-raising campaigns; (7) pricing mechanisms; (8) vehicle access restrictions; and (9) control of land-uses. Drawing on international research and examples of policies to reduce the environmental impacts of transport in urban areas, this article identifies some key lessons for sustainable urban transport in smaller and medium-sized cities in developing countries. These lessons are certainly not always identical to those for megacities in the global south.

While the concept of policy integration is not a new idea within spatial planning discourse, it is becoming increasingly prevalent. Frequently, however, the term is used without any clear definition of what it means, or how it might be achieved. The aim of this paper is to provide more clarity about the concept and to identify the types of actions in the field of planning where integration with policy can be improved. In so doing, the paper assembles a range of material from different disciplines, and identifies some of the key inhibitors and facilitators of policy integration.

An underlying aim of European territorial cooperation initiatives, such as INTERREG, is that they will lead to mutual understanding and learning across national boundaries. However, the effect of mutual learning on national systems and policies of planning is uncertain. After all, spatial planning systems are deeply embedded in their socio-economic, political and cultural context, which can potentially constrain the scope for mutual learning. Moreover, planning systems may have a certain degree of path-dependency, such as the persistence of institutions and cultures. In this paper, we explore the relationship between planning systems and their context and assess the extent to which cooperation and learning might contribute to convergence in styles of planning in Europe, as well as why and how this might be taking place. We take as our context the prevailing social model or model of society, the collection of common social and cultural values. We examine and compare typologies of planning systems and typologies of social models and find a degree of correspondence between them. The examples of England and the Netherlands are used to illustrate this interdependence. However, they also reveal how planning systems and policies in different contexts are changing in similar ways, and perhaps even demonstrate a measure of convergence. In other words, external factors may be overriding or undermining the influence of the national social model. The implementation of planning reforms may be running ahead of wider changes in the social model.

In this paper I extend the debate about land use and urban form. I contend that many empirical studies that have examined the relationships between land use and travel patterns have omitted to consider the socioeconomic dimension, leading to simplistic views about land use and travel. I report the results of a study into the relationships between land use, socioeconomic characteristics, and travel patterns by using data from national and local travel surveys in Britain. The results of the study show that the variation in travel patterns often owes more to socioeconomic reasons that to land-use characteristics. However, land-use planning may still have a significant effect on influencing travel patterns.
