By Dom Nozzi A friend of mine recently told me she heard on her local NPR station today that nearly 700 people have died from car accidents in Colorado this year. Officials, she learned, are concerned that 81% of those deaths have been pedestrians that have been run over, up by 48% over last year. Most all the deaths have occurred, according to this report, at large intersections with wide roads where there are speeds above normal. Apparently, a study is being conducted on how to make these pedestrian crossings safer. She told me she didn’t know how you can do that. That to her, it seemed impossible unless you ban cars or build pedestrian bridges to go over all highways.
