Using Snow to Evaluate Roadway Infrastructure

One cool thing about having snow on the ground is that vehicles leave tracks behind.  This means we know exactly where people are driving and where they aren’t.  Here’s an example of how we can use this to evaluate our infrastructure:

This is a photo of a diagonal diverter recently installed in Minneapolis at 40th Street and 11th Avenue.  The purpose of the diverter is to keep vehicles from continuing straight through on either 40th Street or 11th Avenue. Clearly from the photos, however, folks are just driving right around it.  In these photos, the tracks in the snow on the left and right sides of the diverter shouldn’t be there.
