Introduction:
The links between traffic congestion, accessibility to health services, and equity show how traffic congestion impacts accessibility among different populations. It can also be used to improve health services and land use planning. The study proposes an approach to measuring, analysing, and communicating accessibility to health services in terms of travel time, as opposed to traditional travel time analyses.

Methodology:
We studied the entire city of Cali (2.258 million), assessing accessibility by car to urgent care (tertiary care emergencies) and frequent ambulatory care (haemodialysis and radiation therapy) in July and November 2020. The study is the cocreation of an interdisciplinary multisectoral group involving authorities, academia and other civil society, service providers and beneficiaries.

Results:
Services are far from where most of the population lives, especially some of the most vulnerable. These people pay more to access essential health services. New analyses will indicate potential solutions and their potential impact.

Discussion:
The study used a person-centred design to address the needs of different stakeholders. Studies like this can expand to other services, transportation means, and locations. They allow for integrating health equity with urban planning and enable participatory evidence- informed decision-making.
