Abstract: This research analyzes urban territorial accessibility which allows to explore savings in travel time as an alternative to assess benefits derived from the development of transport infrastructure and their relationship with economic contributions charged to the benefited community (Betterment Levies). This methodology serves as a complement for entities that calculate Betterment Levy (BL) collection used, since, 1921 to finance infrastructure works in Colombian cities. A case study is made of The Carola intersection in the city of Manizales, calculating savings in travel time in the neighborhoods where BL collection will be made, demonstrating mobility benefits that can be generated and justified.
