• Resumen

  • StreetScore, developed by Nikhil Naik at the Massachusetts Institute of Technology and his team, is built on crowdsourced data. It uses a web survey called Place Pulse, which asks people to choose which looks safest out of two images of Boston or New York taken from Google Streetview. Once each image has been scored by humans, an algorithm spots features that correlate with high safety scores, allowing it to look for those features in other streetscapes. It can then create a map of the city, color-coded by perceived safety. The team is also applying the software to Chicago and Detroit.
