Abstract: Bogotá, a paradigmatic case of urban (re)development driven by transport interventions, began transforming its public transport system anew in mid-2010. It was not until 2012 when a gradual implementation of the new integrated public transport system of Bogotá (SITP in Spanish) began. By 2015, about 74% of the new bus routes were implemented. The considerable changes in supply and operational models for public transport during this period redefined travel conditions, having a direct impact on accessibility. Our research analyzes observable changes in accessibility to jobs and houses at both the home and work ends of trips as a result of differences in travel time for respondents to a household travel survey in Bogotá between 2011 and 2015. The paper presents a cross-sectional analysis of accessibility changes, pinpointing low accessibility levels facilitated by the current public transport system to the most deprived groups of Bogotá. Results are presented as access curves by socioeconomic levels and zones that estimate the time required to access workplaces via public transport. Results show that the location of low-income settlements implies a disadvantage as a consequence of spatial segregation that increases distances to job-opportunities. Five years after the implementation of the SITP, public transport in Bogotá still fails to improve accessibility, reinforcing gaps between rich and poor groups instead of closing them.
