| | After analyzing New York's sidewalks, crosswalks, and footpaths, MIT researchers have created the first complete model of pedestrian activity in a U.S. city. "I hope this can inspire other cities to invest in modeling foot traffic and mapping pedestrian infrastructure," says Associate Professor Andres Sevtsuk. "Our models serve as a test bed for making future changes." |
