I mean, you can say it doesn't work all you like, but the reality is that it does, and there is concrete (well, asphalt) evidence right outside my window and all over the rest of the city and country that it works and works well. It just requires the will to design things properly. Separated paths improve safety, they don't cause issues at intersections that I've noticed (and I've been biking through them every days for years), probably because things were designed well to account for this. It's one of those situations where good design becomes mostly invisible so it's hard to spot.

This document describes the crashes involving cyclists in a bidirectional separated bike path[1] which for a couple of years was having close to one crash per month. Here's an example[2] of a drive-out collision. Here's an example[3] of a right-hook near miss. Here's an example[4] of a left-cross collision.

  That looks to my mostly uneducated eye like a badly designed intersection. You can't just slap a cycle lane (especially two-way) in and expect it to work, that's a poor solution. Compare to here, https://goo.gl/maps/F1mufzKACT3XpDZa6 https://goo.gl/maps/F1mufzKACT3XpDZa6, just as a fairly random example. You see that the car traffic is forced, via traffic calming (i.e. the raised footpath) to slow, has obvious lower priority than bikes and pedestrians, and can't really proceed without being strongly encouraged to look first. A couple more interesting samples at the bottom that are designed with safety in mind, and in my experience work well. Taking an existing road, slapping a bike line on one side, and calling it a useful test is not really effective. This is why I mentioned design is important. What is interesting from your PDF (which I just skimmed, so don't know if it's representative) is that the number of people cycling increased, so it looks like people felt it was safer even if it really wasn't. I suspect that if you managed to get that up to real numbers of people cycling, then drivers would naturally become a lot more aware also. * https://goo.gl/maps/DLHUVjadJcM2y8tG7 https://goo.gl/maps/DLHUVjadJcM2y8tG7 - light controlled, bikes tend to sit slightly forward of the cars in order to be visible. * https://goo.gl/maps/bhLYgqiVBccnq2i27 https://goo.gl/maps/bhLYgqiVBccnq2i27 - roundabout with (in order of priority) trams, bikes, busses/cars
