first the time pedestrians are given to cross the street has been calculated not with their real needs in mind especially for the elderly but considering the needs of moving cars second at many intersections turning on red has been allowed ie cars can turn into an intersecting street and go over a crosswalk when it is green for pedestrians both decisions can make crosswalks more dangerous for pedestrians especially those who walk more slowly or have vision problems green time for pedestrians remained the same but it was enough for the smaller distance
