I'm not sure what your link is supposed to show, but it seems to be pretty clearly in favor of separated bicycle infrastructure: "When accounting for sidewalk riding, normalized risk along road segments and intersections, and riding in the opposite direction of traffic, the results of studies arguing for shared vehicle and bicycle infrastructure suggest that dedicating right-of-way to bicycles may, in fact, improve roadway safety. There are additional, more recent studies designed to assess safety differences between mixed traffic, bike lanes, buffered bike lanes, and separated paths that show safety in separation."
