In the context of still-low-but-rising levels of motorization and economic growth, increasing social and spatial inequalities, and growing concerns about air pollution and climate change, the formulation and implementation of policies, practices and partnerships that can support an accelerated implementation of sustainable mobility policies is an urgent concern for rapidly developing cities. This paper seeks to contribute to reframing some of the knowledge and methodologies produced in and about cities of Sub-Saharan Africa, through a comprehensive assessment of mobility patterns and accessibility needs within a larger debate about mobility transitions and sustainable development. By deploying a mixed-methods approach that builds upon case-study focus groups and city-wide accessibility and mobility analysis in the city of Freetown, Sierra Leone's capital, the paper maps travel patterns and their links with structural factors such as urban form, poverty, informality and social identities at the macro, meso and micro levels. The paper also presents evidence from a variety of methods that illustrate the significance of accessibility-centred information and analysis for establishing policy priorities for improving urban mobility and accessibility in the local, African and global contexts.

As a clean, accessible and healthy transport alternative, the benefits of cycling have been well-documented and suggest positive health, environmental and affordability outcomes. Despite a favourable rhetoric for cycling, in many cities in Latin America, its uptake has gained more traction among younger and carless populations than frequent users of private motorised vehicles. Recognising this reality, our article poses arguments for cycling beyond its classic benefits via direct comparisons of its performance against that of private cars. Our paper compares cycling and car-based trips, presenting evidence in cycling for policy and decision-making targeting a demand segment that has historically been more resistant to modal shifts to sustainable mobility. We contrast performance of both modes in relation to coverage and accessibility, testing different modal shift scenarios in the context of Bogotá, Colombia's capital city. As a city that has been recognised in the international literature for both its successes in urban transport policy and its persisting mobility and access inequalities, Bogotá's contrasts are an ideal setting for this research. We build on a geo-coded household travel survey for 2015 and API-sourced datasets to develop spatial coverage and potential accessibility metrics for cycling and car-based trips. Findings suggest Bogotá's large potential for further increases in cycling, particularly from car-users, which can lead to overall societal gains in terms of sustainable accessibility and present a fertile ground for bike-sharing systems. The paper builds on spatially and socially distributed findings to identify areas with the highest potential for bike-sharing in Bogotá. [ABSTRACT FROM AUTHOR]
