A city is the most dramatic manifestation of human activities on the environment. This human-dominated organism degrades natural habitats, simplifies species composition, disrupts hydrological systems and modifies energy flow and nutrient cycling. Sustainable urban development (SUD) is seen as a panacea to minimise these externalities caused by widespread human activities on the environment. The concept of SUD has been around over a considerably long time as the need to adopt environmentally sustainable behaviours made the international community commit to it. However, to date such development has not been achieved in large scales anywhere around the globe. This review paper aims to look at the SUD concept from the lens of planning and development integration to generate new insights and directions. The paper reports the outcome of the review of the literature on planning and development approaches-i.e. urban planning, ecological planning, urban development, SUD-and proposes a new process to support the efforts for achieving SUD-i.e. integrated urban planning and development process. The findings of this review paper highlight that adopting such holistic planning and development process generate a potential to further support the progress towards achieving sustainability agendas of our cities.

“…At the same time, many academics and decision-makers have appreciated the importance of integrating urban and infrastructure (more particularly transport) development to achieve a more sustainable urban development (Newman and Jennings 2008;Yigitcanlar 2010a, b;Goonetilleke et al 2014). This lead into development of various methods to assess and measure the integration of transport and land use (Yigitcanlar and Dur 2010;, examine the transport disadvantage levels (Duvarci and Yigitcanlar 2007;Duvarci et al 2011), analysis of existing travel patterns and trends (Yigitcanlar et al 2007b;Zhao 2010) and also impacts on the natural environment (Alam et al 2006;Tuzkaya 2009;Liao et al 2013). On top of these, the papers of this Special Issue reports new empirical approaches and investigations from different parts of the world that contributes to the wealth of knowledge in investigating the interplay between transport, land use and the environment.…”

Investigating the interplay between transport, land use and the environment: a review of the literature

Integration of land use and transport decisions to achieve sustainable travel behavior has been considered an integral element for sustainable urban development. However, before the popularity of urban sustainability concept, land use and transport interaction had been scrutinized as strictly separate entities in the urban planning and development domains. Fortunately, today the concept of sustainability has been pushed to the forefront of policy-making and politics as the world wakes up to the impacts of climate change and the effects of the rapid urbanization and modern urban lifestyles. The paper therefore aims to highlight the importance of the interplay between transport, land use and the environment. This review paper provides evidence from the literature including the Transport, Land Use and the Environment Special Issue contributions and global best practice cases to showcase new empirical approaches and investigations from different parts of the world that contribute to the wealth of knowledge in exploring the interplay between transport, land use and the environment thoroughly.

“…climate change) and local (e.g. air pollution) environments and thus is one of the major contributing factors to unsustainable urban development (Alam et al 2006;Yigitcanlar and Dur 2010;Yigitcanlar and Teriman 2014). Climate change is one of the most important policy challenges facing the world population caused by the increase in greenhouse gases in the atmosphere, and the most prominent contributor to climate change is the burning of fossil fuels (Line et al 2010;Liao et al 2013).…”

Australian baby boomers switched to more environment friendly modes of transport during the global financial crisis

et al. 2014

The global financial crisis (GFC) in 2008 rocked economies around the world. Several intermediate outcomes of the GFC included loss of jobs and reduced income. Relatively little research has, however, examined the impacts of the GFC on individual level travel behaviour change. To address this shortcoming, HABITAT panel data were employed to estimate a multinomial logit model to examine mode switching behaviour between 2007 and 2009 of a baby boomers cohort in Brisbane, Australia-a city within a developed country that has been on many metrics the least affected by the GFC. In addition, a Poisson regression model was estimated to model the number of trips made by individuals in 2007, 2008, and 2009. The South East Queensland travel survey datasets were used to develop this model. Four linear regression models were estimated to assess the effects of the GFC on time allocated to travel during a day: one for each of the three travel modes including public transport, active transport, less environmentally friendly transport; and an overall travel time model irrespective of mode. The results reveal that the baby boomers switched to more environmentally friendly travel modes during the GFC.
