One key principle when watching these videos was the importance and priority of safety and efficiency. For example, in the videos about Dutch junctions and Roundabouts they were specifically designed to be the most effective intersections in the world. For example, I learned that cycling lanes in major metropolitan areas are very ineffective and dangerous. The role of junctions in places like America or England is to give the car more safety and right of way (even though the right of way goes to the pedestrian, cyclist, THEN motor vehicle. However, in the Netherlands the junctions are very safe and work in an almost roundabout fashion. They are protected waiting areas and a completely free right turn. Unlike many other cities there is also a separate bike light to coordinate a smoother left-hand turn.
The intersection I visited is right outside my building in New York city. It is on 74th and 1st avenue in Manhattan. Since both of the directions at the intersection are one way I redesigned it so it would look like a Dutch junction if it were one way. First of all the bike lane should be on the right of traffic. In real life the bike lane is on the left of traffic. Then the bus lanes would be moved to the left side of the street, were street parking would be. The aim would be to use less space and make drivers slow down at these intersections.
