Solarpunk Urbanism

It's about the Dutch-style bike intersection, specifically the first one built in Montreal. It sort of extends bike lanes through the intersection. Instead of bikes and cars mixing in the entire square area of the intersection, there are concrete curb islands inside each corner of the intersection separating car lanes from bike lanes. Turning cars have to go around the inside of the islands, which makes drivers slow down which adds safety. Bike lanes are on the outer sides of the islands which reduces the distance cyclists have to ride where they might intersect with a car since cyclists are protected by the islands for parts of the crossing through the intersection. There are other interesections that use the same idea, but apply it to pedestrians rather than bikes.

Drivers complain that the design is a "labyrinth". The video argues people will get used to it when there are more of these.

Left turns are intended to be two-phase, like with unprotected left-turn boxes. First you ride straight across the intersection. Then you stop in a box in the perpendicular bike lane on the other side, which is protected by one of those islands. The box provides space to turn left before stopping. Then when you get a green light for that direction you proceed.

Some cyclists seem to be confused about how left turns are supposed to work. One cyclist merged into traffic before turning, performing the turn in the car lane. Another cyclist crossed both lanes of car traffic before the intersection, rode across the intersection in the bike lane, but going the wrong direction, and finally turned left into the bike lane on the other side.

Car brains complain about a new intersection type imported from Europe. It's nothing special, but prevents cars from cutting corners when turning and gives more space space to pedestrians and cyclists. However, dumb cyclists also have been using it wrong, but there's dumb people everywhere regardless if the intersection type.

Intersections that provide more dedicated space where bicycles and pedestrians aren't using the same roads as cars are good. Sharing the road with cars is bad and dangerous if you aren't in a car.

I looked at the video very quickly. It's a description of the dutch-syle bike protected intersections and how to navigate them with a bike.

The Brilliance of Dutch-Style Protected Bike Intersections

This video explores the design and benefits of Dutch-style protected bike intersections, contrasting them with conventional intersections and addressing common criticisms. The video argues that these intersections, while initially confusing to some, significantly enhance cyclist safety and accessibility by providing dedicated space, protection, and predictability.

Key Points:

• Problem with Traditional Intersections: Traditional intersections can be chaotic and dangerous for cyclists due to car traffic, unclear right-of-way, and lack of dedicated space.
• Protected Intersections: Dutch-style protected bike intersections aim to solve these problems by extending protected bike lanes through the intersection, giving cyclists more space and separating them from car traffic.
• Key Features: These intersections typically include:
  • Dedicated bike lanes and waiting areas.
  • Traffic signals that give cyclists a head start.
  • Concrete islands to separate cyclists from cars and shorten crossing distances.
• Benefits:
  • Increased safety for cyclists.
  • More predictable and intuitive navigation.
  • Encourages slower and wider turns for drivers, improving overall safety.
• Examples: The video showcases examples of protected intersections in Montreal, Vancouver, Chicago, and Ottawa, highlighting Ottawa as a leader in implementing them at scale outside of the Netherlands.
• Addressing Criticisms: The video acknowledges initial confusion and negative reactions to these designs but emphasizes that with experience and proper implementation, they become intuitive and essential for safe cycling.
• Importance of Widespread Adoption: The video concludes by advocating for the widespread adoption of protected intersections, particularly at larger and more dangerous intersections, to make cycling more accessible and safer for everyone.
• Montreal's Implementation: Montreal is highlighted as a city beginning to embrace these designs, with several examples of protected intersections or elements being implemented.
• Two-Stage Left Turns: The video explains the intended method for making left turns at these intersections, which involves a two-stage crossing, and addresses common mistakes cyclists make when navigating them.

Some sort of intersection design, I'm guessing from the video description.
