Social Design Don Luis Traffic signal by CasBeVilla Team “Many countries have begun to implement policies to encourage walking as an important mode of transport. Pedestrian risk is increased when roadway design fail to plan for and provide traffic control mechanisms that separate pedestrians from vehicles. Traffic crashes in general are estimated to cost between 1 and 2% of gross national product” (WHO). Don Luis is a 3D traffic signal that binds to a yellow 2D line painted on the sidewalk to avoid the pedestrian cross the street at a different place to zebra. Designed with a sociocultural analysis and not merely from aesthetic guidelines.
