If you care about the interaction of cyclists and motorists, of which we have many of both around Park City, this New York Magazine article may be interesting to you. It seems that a study (albeit online) seems to indicate that the choice of wording on signs, greatly influences interactions between different groups on the roads. For instance, many locales will have signs saying “Share the Road” trying to indicate that bikes and cars should coexist on our roadways. They don’t seem to achieve good results. However, instead saying, “Bicycles May Use Full Lane” yields superior results.
Studies like this point to interesting ideas how to make our interactions better everywhere form ski slopes, to trails, to roads.
