Although walking is an excellent way to enjoy the great outdoors and get a little bit of extra exercise, there are certain days when it might be safer to use another mode of travel. While warmer weather and sunshine often inspire Americans to walk more, resulting in a significant increase in pedestrian traffic, sunny summer afternoons during the midweek are surprisingly, not the most dangerous. In fact, the highest number of pedestrian accidents occur during the winter months, with approximately 49 percent of all deaths happening on Friday, Saturday or Sunday, and 72 percent occurring after dark.
