Preventing road deaths through safe system design

Safe System design is a public health framework for preventing traffic accidents and death. The system adapts and transforms roads as part of a broader system of reforms. In Bogotá, in addition to a city-wide speed limit, high-risk corridors were identified using geo-referenced collision data and modeling. Multiple locations were transformed into pedestrian friendly streets that encourage lower traffic speeds by using speed bumps, bicycle lanes, wide sidewalks, benches, and planters. Officials note that the change has led to a decline in fatalities.
