Abstract

The development of Bus Rapid Transit (BRT) systems world-wide has witnessed tremendous growth in recent years, most notably in cities throughout the developing world. These large, city-wide transportation projects are often central to larger urban revitalization plans intending to foster economic growth and alter city images to both residents and to outsiders. Crucial to the success of such ambitions is a system that provides equitable access to all residents and one that provides access to a large number of urban opportunities. The purpose of this paper is to explore the spatial accessibility landscape created by newly implemented BRT system in Cali, Colombia in terms of both access to the system itself and access to three distinct activities around the city. In particular, the equitable distribution of accessibility patterns is explored in relation to neighborhood socio-economic strata. Findings indicate that walking access to the BRT system is greatest for middle income groups and most limited for neighborhoods in the highest and lowest socio-economic strata. Accessibility values to activities are largely bound to the spatial distribution pattern of activities; most equitable for intentionally dispersed recreation site, and least for spatially clustered hospitals.
