New research article-Spatial structure, intra-urban commuting patterns and travel mode choice: Analyses of relationships in the Kumasi Metropolis, Ghana

Abstract (click to download)


Commuting patterns in Sub-Saharan African cities are evolving in tandem with rapid levels of historical urbanization. Yet, our understanding of how the prevailing urban spatial structures shape travel patterns is limited. This study explores the land-use-travel nexus in the Kumasi metropolis in Ghana, by focusing on work commuting. It uses newly available land-use datasets to present TAZ-level analysis of the distribution of land-use activity types. From a survey of a representative sample of 1158 workers, the characteristics of commuters and their travel patterns are examined. The analyses reveal a unique structure for the urban system, that is polycentric in both morphological and functional dimensions, but with a relatively stronger centre (i.e. CBD). Overall, home-work commute flows strongly reflect the prevailing spatial structure. Residence in suburban neighbourhoods; non-home-based employment locations; home-work distance exceeding 0.3 km; and relatively higher-incomes influence motorized transport choice and car-use for work journeys. Walking to work is strongly associated with lower-income levels, residence in historical-core neighbourhoods and home-based employment. The paper contributes to conceptualizing, theorising and understanding the spatial structure-travel nexus at the intra-urban scale by focusing on a previously unexplored urban context. The implications of the findings for integrated urban development and transportation planning are highlighted.

Special Issue Call for Abstracts on “Autonomous mobility transitions: socio-spatial dimensions and the role of urban planning and policy”

Special Issue of Cities, the International Journal of Urban Policy and Planning 



Advances in Artificial Intelligence (AI) and digital technologies are set to transform many facets of society, including the way we travel and interact in cities. Today, AI-driven and Information and Communication Technology (ICT)-enabled fully autonomous vehicles are being introduced into a number of cities around the world.

As automated driving becomes pervasive in cities, profound societal and spatial impacts will be inevitable. An important socio-spatial dimension of automated driving is the likely impact that this new form of mobility will have on the structure of cities and on the configuration of streets and public spaces.

Introducing AVs into existing built-environments and transportation systems could cause major disruptions and worsen problems of unequal access to opportunities, especially if investments needed in providing public transit are diverted into building infrastructure for driverless vehicles.

Moreover, the transition to autonomous mobility will have implications for creating inclusive and age-friendly urban futures. However, to do so, innovative urban development and transportation planning strategies that could leverage autonomous vehicles to respond to the mobility needs of different groups of people, will be critical.

In the logistics and local goods delivery sector, urban planning must respond to new challenges associated with the technology, including planning for the supporting infrastructure such as road and street systems, electric vehicle charging stations and warehousing and bulk-breaking facilities.

Economic impacts, including potential job losses in the transportation sector are also expected because of automation. In addition, fundamental questions regarding the ownership, management and access to data that users of autonomous transport services would generate, need addressing.

Thus, the urban fabric, as well as different groups of people in different parts of the city may be affected differently in the transition to autonomous mobility. How can urban planning and policy respond to the wider socio-spatial implications of autonomous mobility?

Focus of the special issue and themes

This special issue seeks to bring together a collection of critical perspectives on the social and spatial implications of the diffusion of autonomous vehicles in cities. In particular, the special issue will seek to publish contributions that stimulate debates and improve our understanding of how urban planning and policy can respond to this potentially disruptive technology as it intersects with cities. The contributions can be empirical, theoretical and methodological.
Topics can include (but are not limited to):

  • autonomous mobility and urban spatial structure
  • affordability, equity and inclusivity implications of autonomous mobility
  • accessibility implications of autonomous vehicles for motorized travel
  • accessibility implications of autonomous driving for different age groups including children, young adults, people in old age, and for individuals with disabilities and the urban poor
  • implications of autonomous driving for vulnerable road users, including cyclists and pedestrians
  • implications of autonomous mobility for mass transit in cities
  • possible travel behaviour changes around driverless vehicles
  • governance of autonomous mobility transitions
  • the nexus between autonomous mobility and public health
  • privacy and security concerns around autonomous vehicles
  • the nexus among autonomous vehicles, emerging mobility concepts (e.g. shared-mobility, mobility-as-a-service) and urban sustainability
  • autonomous mobility transitions and employment in the city
  • urban planning implications of automation in freight movement in the logistics sector

New Book on Spatial Planning

This book documents and analyses spatial planning in Ghana, providing a comprehensive and critical discussion of the evolving institutional and legal arrangements that have shaped and defined Ghana’s spatial planning system for more than seven decades…

Overview of the book

bookPlanning systems are deeply rooted in the socio-cultural, legal, political and economic situations of the countries that use them to achieve specific development goals.

This book documents and analyses spatial planning in Ghana. It provides a comprehensive and critical discussion of the evolving institutional and legal arrangements that have shaped and defined Ghana’s spatial planning system for more than seven decades; the contemporary policy instruments and mechanisms for articulating and implementing policies and proposals at multiple scales; and the formally established procedures for development management.

The book also covers important themes in contemporary spatial planning discourse including: the evolving meaning, scope and purpose of spatial planning globally; the scales of spatial planning (i.e. national, regional, sub-regional and local); multi-level integration within spatial planning; public participation; the interface between urbanization, sustainable growth management and spatial planning; spatial planning and housing development; integrated spatial development and transportation planning; and spatial planning and the urban informal economy.

The book is written for undergraduate and graduate students, and academic researchers and practitioners/policy-makers in the multidisciplinary field of spatial planning. Audience who seek an international perspective in spatial planning systems and practices are primary target of the book.
