I walked from the South end of campus to the North end of campus and back on Monday, the first day of the snowstorm, and noticed something about the sidewalks. The sidewalks that had been cleared by the tractors using the large rotating brush were cleared of snow but not ice. These sidewalks were much more slippery than the ones not cleaned, or cleared by shovel. It is obvious that snow gives better traction than ice, so this begs the question, why does the University use those brushes when they make it more dangerous for people to walk around? I understand that some people do not realize that there is often ice under the snow, but unless they are putting down sand, salt or ice melt after they expose the ice, they are not doing anyone a favor. All they seem to be doing is polishing the ice. With all of the technology available, I can't help but believe that there has to be a better solution. Does anyone have experience in this area, or at least know of a decent alternative? If you do, please make suggestions to the University so that we might have a better solution for the next snowstorm.
