We wanted to figure out the velocity of cars passing by our High School. We measured 30meters between two points and had people standing at both points. We also had two people recording the time it took for each car to pass: one would say go when the car passed, heading south, and the two would start their time, then stop it when it passed the second person 30m away.

So we concluded that, it being near a school, cars are more cautious than in other environments- say one of our streets. While many still text and don’t seem to pay attention (like the one young adult that didn’t move for roughly a minute after the light turned green, angering the cars behind them), there where some that are more cautious, even waiting for us to cross the street when they technically did not have to.

The funny thing that everyone in our group, before conducting the experiment, believed that many of the people would speed by when the light was green. The truth is something we didn’t expect. Many people were actually under the speed limit. We cannot tell if this was because us students were standing there or because of the stoplight (and the possibility of a police car loitering around) or just because they were good citizens (hah). So, ultimately, there are not speeding problems on Cooper Road… at least during school hours J
