This research explores the benefits of a proposal for urban road infrastructure which aims to improve road connection between northwest and western neighborhoods of the city of Manizales, Colombia, as well as to expand the ring of urban mobility that runs through the city. By calculating the global average accessibility and comparing the current and future situation, by averages of savings gradient, timesaving generated by this alternative are obtained in terms of average travel time. There is evidenced that suggest the road infrastructure proposal would generate savings in the average travel times for the entire city, especially to the neighborhoods located in the area of direct influence.

Discussion: TrUST is innovative in its use of a mixed-methods, and interdisciplinary research approach, and in its systematic engagement of citizens and policymakers throughout the design and evaluation process. This study will help to understand better how to maximize health benefits and minimize unintended negative consequences of TransMiCable.

ResumenLa presente investigación aplica técnicas geoestadísticas para explicar el nivel de cobertura que presenta la infraestructura de transporte de la ciudad de Quibdó en relación a los Nodos de Actividad Primaria (NAP), los cuales son aquellos que permiten suplir las necesidades diarias mínimas de una población: Salud, Educación, Universitarios y Seguridad. La metodología se basa en un análisis de accesibilidad a estos nodos mediante el cálculo de la Accesibilidad Media Integral que ofrece la red de infraestructura. El objetivo es analizar la ubicación de los NAP a partir de su relación con las características operativas de la red de infraestructura del transporte. Se obtuvo que los NAP que mejores características de cobertura espacial poseen son Educativos, seguidos por los NAP Salud y Universitarios, los cuales reportan niveles de cobertura semejantes de las variables población, número de viviendas y área; mientras que los nodos que reportan una cobertura más deficiente son los de Seguridad.

The methodology is based on an analysis of accessibility to these nodes through the calculation of the Integral Mean Accessibility offered by the infrastructure network. The objective is to analyze the location of the PANs based on their relationship with the operational characteristics of the transport infrastructure network. It was obtained that the PANs that have the best spatial coverage characteristics are Educational, followed by the PAN Health and PAN Universities, which report similar levels of coverage of the variables population, number of households and area. While those nodes that report a poorer coverage are those of Security.
