U.S. Traffic Engineers: It is safe for a child to make a 73’ crossing of 50+ MPH multi-direction traffic in an unmarked (but legal) crossing:

CROW/Dutch Traffic Engineers:  10’ and one direction of motor traffic at a time is the maximum safe crossing distance for 31 MPH traffic.

Which of these do you want your 8-year-old child to use each morning?

Which one results in more children walking/biking to school, healthier children, better academic performance and 1/5 as many children killed?
