These stragglers are often the people most likely to get hit by a car--children, the elderly, disabled, or those with limited mobility. 3-4 seconds might not be enough for them to even react to a signal change, let alone safely cross to the other side. | |

Dec 31, 2011 at 1:07 | comment | added | djeidot | I don't follow that. Pedestrians have flashing green lights warning that it's going to turn to red, and the red light for pedestrians shows up 3-4 seconds before the green light for cars shows. Plus, in most cases pedestrians can't see the traffic lights for cars. | |
