Abstract In this study, we evaluated and forecasted the cumulative opportunities for residents to access radiotherapy services in Cali, Colombia, while accounting traffic congestion, using a new people-centred methodology with an equity focus. Furthermore, identified 1–2 optimal locations where would maximise accessibility. We utilised open data publicly available big data. Cali is one of South America's cities most impacted by congestion. Methodology: Using approach, tested web-based digital platform developed through iterative participatory design. The integrates data, including location services, disaggregated sociodemographic microdata population places residence, travel times from Google Distance Matrix API. used genetic algorithms identify services. predicted accessibility (ACO) ranging peak congestion free-flow conditions hourly assessments 6–12 July 2020 23–29 November 2020. interactive openly available.
