Cities throughout the South, and especially in Florida, are danger zones for pedestrians—not because of local crime, but because of how streets are designed. A new study by transportation planning experts examined fatalities on foot across the U.S. (76,000 in the past 15 years) and came up a Pedestrian Danger Index (PDI) which is designed to show which urban areas are the riskiest to walk. The four cities with the highest PDI are all in Florida: Orlando, Tampa, Miami, and Jacksonville. Rounding out the top 10 most dangerous were Memphis, TN, Raleigh, NC, Louisville, KY, Houston, TX, Birmingham, AL, and Atlanta. GA. Researchers noted that Orlando, with a pedestrian fatality rate of 2.9 per 100,000 residents, led the nation despite the fact that few people actually walk to work there (1.3% of the population).
