Temperature at departure = 33° F (1° C)
450 students attend my youngest son's elementary school. Of those 450, 180 ride the bus, leaving 270 to get to school via parents driving them, walking or riding a bike. Yesterday I took my camera along to get a picture to use as a foundation for a presentation I'm trying to put together to encourage more kids to get out of their parents cars and becoming self-propelled. Yesterday was an anomaly; there were two bikes in the rack. Normally there is only one, my son's.
This was the calm before the storm. Once the kids come out, more cars show up and everyone is jockeying for position and struggling to get out.
So, here comes the science: Percentage of kids that rode their bike yesterday = 0.7. I do not have any numbers on how many kids walk, but I plan on chatting with the two crossing guards stationed at the two busiest intersections on the main street (one of them is a half mile away from school).
Over the last two weeks:
The average morning temperature has been 35°.
Average afternoon temperature = 54°.
Average number of children who have riden a bike to school = 1.5
Average percentage of students who have riden their bike to school in the last two weeks = 0.5.
My point is, the weather was nice enough that many of the kids who are driven to school could walk. Parents who drive to drop off and pick up their children because they are afraid to let their kids walk should try walking too. I noticed one parent drove 0.2 miles to pick up their child. That is 352 yards. I don't get it, why didn't they walk? It was 48°, a beautiful day. My school isn't an isolated case; check out Friz's post on CommuteByBike for an example that trumps my 352 yards.
