Pedestrian traffic in public space is associated with a level of service (LOS) that qualitatively describes the operating conditions according to the spaces available in square meters per pedestrian. Daily, people need to travel to their workplaces, schools, and universities, or to carry out any other activity using means of transportation such as walking, bicycle, car, or public transport, among others. In many cases, at least one walkable path is required regardless of the type of transport means selected to make a trip according to its accessibility. This article presents the analysis of piezoelectric power generation on the main street in the city of Barranquilla, Atlántico (Colombia), considering the pedestrian volume and the level of service of the sidewalks, according to the geometry of the road an energy consumption is estimated, then this data is compared with pedestrian accessibility indices (walkability index) of the city, with the aim of defining the functionality and applicability of the measure for the generation of energy from innovative and environmentally friendly sources. The results show that the city requires substantial modifications to make it more walkable, promoting active transportation and the inclusion of piezoelectric power generation strategies is an option to make a public space potentially sustainable.
