When is it that design can change human behavior? In a sense it is when that design promotes the change in a positive way. In Bogotá it was when the mayor, Enrique Peñalosa, decided to focus on redesigning transit to a more commuter friendly environment. In a time when traffic was a huge problem in the area many outside companies, such as some in Japan, advised that there need to be more roadways, and an addition of 7, yes that's right 7 new elevated highways to help the city. Peñalosa instead decided to focus on something that would help everyone, not just those that had vehicles. It was to promote a new bus system, called the TransMillenio, as well as more pedestrian friendly walks. This was a way to improve everyone's lives, not just those fortunate enough to have a vehicle. This mentality gave everyone the idea that Bogotá was there's. Everyone now had a new mindset that the city wasn't owned by any one group, by any one class, by any one person, but rather was owned by everyone. With this mindset it changed the human behavior of those in some of the poorer areas of Bogotá and reduced their murder rate from one of the highest in the world to that lower than Washington, D.C. So what can you do to inform design to change human behavior for the better?
