Evaluación de la sostenibilidad del transporte particular urbano en la ciudad de Medellín (Colombia)

The main objective of this study is to develop a comprehensive tool for sustainability assessment of private urban transport, which is applied in a case study in Medellín (Colombia). A system dynamics model is built to assess the urban transport sector by integrating sustainability indicators. The results show that policies based on restrictions or prohibitions do not make significant progress, while financial policies can reduce the need of using private vehicles. Financial policies can also better achieve a sustainable diversification of modes of transport. It is observed that an increase in vehicle fleet can, in the long term, create other problems such as higher car emissions, air quality deterioration, and disease rise in the population. In terms of sustainability, it is concluded that policy flexibility on private vehicle purchases leads to an increase in vehicle fleet.
