A great video introduction to protected multimodal intersection design, from Nick Falbo at Alta Planning, via People for Bikes and their Green Lane Project:
The design is based on long-standing Dutch standards, and actually embodies the prioritization of modes that Boulder’s TMP lays out (but which our physical infrastructure often fails to implement). These are intersections that just about anyone can walk or ride or drive through safely and with minimal stress. They’re not standard in the US. Yet. Let’s change that!
