It is estimated that around 600,000 motored vehicles enter the city of Asunción each day, adding a lot of pressure to the already dense traffic. The car-centric design of cities like Asunción, Ñemby and Fernando de la Mora, makes urban mobility uncomfortable and less safe for pedestrians, as well as unfriendly towards more sustainable modes of transportation like bicycles. Interim tactical urbanism interventions can work as means to increase road safety and promote citizen participation.
