Abstract

The concept of social justice is increasingly called upon in the assessment of the social and environmental sustainability of urban transport. This paper brings together two strands of the literature on this topic: the role of accessibility in social inclusion and the distribution of the environmental impacts of transport. Using the Lisbon Metropolitan Area as case study, we test if there are cumulative social inequalities in terms of accessibility and pedestrian mobility, considering that the latter depends on local environmental quality. We use GIS methods to estimate a series of neighbourhood-level indicators, such as private and public transport accessibility to jobs and urban facilities, community severance and pedestrian exposure to traffic noise. Neighbourhoods are then classified based on the scores of those indicators at two moments in time. We found six clusters. Accessibility increases and pedestrian mobility decreases as we move from the ‘main centre’ towards the ‘suburban’, ‘small centres’, ‘semi-rural’ and ‘rural’ clusters. A sixth cluster is labelled ‘multiple disadvantages’ and groups dispersed neighbourhoods that fare poorly in all indicators. The clusters are then characterized in terms of their socio-economic composition. We find that central areas usually have elderly populations, while rural areas and the “multiple disadvantaged” cluster tend to have low-qualified populations. We also test if disadvantages based on a neighbourhood’s location persist after accounting for the daily destinations and travel modes used by its population. We find that ‘multiple disadvantaged’ areas have the poorest scores in time to work, effects of congestion, and pedestrian noise exposures for commuters on the way to work. The main conclusion is that ‘hotspots’ of multiple transport-related disadvantages tend to have populations traditionally at risk of social exclusion. More emphasis should be put on locally-based interventions on and public participation methods in the definition of strategies for urban transport planning.
