Lis: You forgot to mention on the third pic down what it's about, and I'm incredibly impressed, I never thought North Am would do it, but there are *four* examples underway.

http://cityofdavis.org/home/showdocument?id=3296The protected intersection, also known as a Dutch junction, applies simple design techniques to foster an enhanced travel experience for bicyclists and pedestrians. The protected intersection features many of the same safeguards and comforts that cyclists enjoy while riding in the on-street bike lanes of Davis – dedicated travel ways and separation from automobile traffic – to allow for safe passage through intersections. Inspired by Dutch traffic designers and new to the United States, the protected intersection represents an advancement in safe multi-modal intersection design for Davis.
In a collaborative effort between the City of Davis and the New Home Company, the concept of the protected intersection is being applied to the intersection of E. Covell Boulevard and J Street, the primary gateway to The Cannery neighborhood. Upon completion, Cannery Junction will improve bicycle and pedestrian travel to The Cannery and other destinations along the E. Covell Boulevard corridor. The project demonstrates a continued commitment to active transportation throughout the Davis community.

By Felicia Alvarez From page A4 | May 01, 2016
On Tuesday, the Davis City Council is set to weigh options for a new bike path leading out of The Cannery, including several grade-separated improvements for the bike tunnel near H Street.
While The Cannery’s development agreement originally favored a path that would travel through several adjacent apartment complexes, a lack of compromise between the city and the landlord is leading city staff to recommend a pathway connecting to Covell Boulevard, instead.
The original “Preferred Option” would have placed a path running south from the Cannery through the neighboring Cranbrook and Pinecrest Apartments and down to the H Street tunnel. City staff and the landlords never were able to come to an agreement on the path, however.
“A lot of it was design considerations,” said Mike Webb, assistant city manager. “There’s entryways to apartments and trees that would have to be worked in. It’s a considerable design challenge.”
The council had the alternative of condemning the land before the December 2015 — the deadline set by the development agreement — but decided against initiating the proceedings. The cost of acquiring the land would have fallen on the city, not the developer, Webb said.
With the December deadline passed, the Preferred Option was taken off the table. Instead, city staff is recommending that the council adopt “Bike Path Option 1,” which also was analyzed under the project’s environmental impact report
This second option would see the new bike path start from the southwest corner of the Cannery and run south along the railroad tracks, before sweeping eastward to connect to Covell Boulevard bike path.
Before siding with Option 1, the city initiated a study of several under and over crossing alternatives near H Street. The over crossings would have cost about $7 million while the under crossings would have incurred $10 million in costs, all of which would be covered by the developer.
The developer is only required to pay $1.4 million for the path — the approximate cost of Option 1 — and the city would have to pay the difference if the council decides on one of the alternative bike paths, Webb said.
In May 2015, city staff amended the Cannery’s development agreement to make time for the alternative bike path study. The amendment removed the requirement that a bike path be put in before almost a hundred Cannery units could begin construction.

https://cyclemontreal.org/2015/08/18/first-protected-intersection-for-bicycles-in-north-america/The bicycle- friendly City of Davis, California has built the first protected intersection for bicycles in North America. The intersection is, for the moment, one-of-a-kind on this continent in that it offers cyclists passage through the intersection that is both physically- and time- separated from vehicles. An article in the Davis Enterprise highlighted some of the aspects of the design as well as some reactions from locals using the intersection.
As I mentioned in previous posts, protected bike lanes (that protect cyclists from vehicles along segments between intersections) are not enough to ensure safe passage for cyclists on major arterials. Most interactions between different road users occur at intersections, which is where the “protected bike facility” ceases to offer protection. In order to create infrastructure that is safe and comfortable for cyclists both road segments and intersections must be protected.

There are many great design elements in the protected intersection – they can be summed up in four features:
The City of Montreal would be wise to look to the City of Davis as inspiration and pilot some protected intersections where highly-used protected bicycle facilities cross major arterials, such as: De Maisonneuve at Peel, Rachel at Saint-Denis and Rachel at Papineau.
- A forward waiting area gives cyclists stopped at a red light a leg-up on motorized vehicles. This feature makes cyclists considerably more visible to motorists and allows them to enter the intersection before the first motorized vehicles after a red light. This feature is similar to the bike boxes (the green painted rectangles located at several intersections in Montreal including: Milton and University, Laurier and St. Laurent and, more recently, Villeneuve and St. Urbain), however it offers even more comfort and security because cyclists are protected by a curved concrete structure creating a corner refuge island.
- In addition to creating a safe place for cyclists to wait, the corner refuge island has a number of other safety benefits. Firstly, it narrows the road making it virtually impossible for motorists to take a right turn at reckless speed. This dramatically reduces the likelihood of a right-hook collision between cyclists traveling through the intersection and right-turning cars. The presence of the refuge island also creates space for a waiting area for turning motorized vehicles. This area allows turning cars to clear through the intersection enabling vehicle flow through the intersection and gives the turning motorist full visibility of cyclists before clearing the waiting area and completing the turn.
- The setback crossing gives physical separation between pedestrians/cyclists and turning vehicles and allows all users more time to react to the presence of other users in the intersection.
- A dedicated bicycle signal phase further reduces potential conflicts between cyclists and turning vehicles. There are several ways to incorporate this feature into a protected intersection – each way offering a different level of protection. Firstly, a leading bicycle interval gives cyclists a three to five second head start before turning vehicles get a green, when paired with the forward waiting area, this gives cyclists both space and time to clear the intersection before vehicles can enter the cycling space. A more secure option, the fully protected signal phase, fully separates conflicting movements between through travelling cyclists and turning vehicles. A third option, the green scramble phase, gives all vehicles movements the red-light while allowing all cyclist movements through the intersection. This type of phase programming exists for pedestrians in many cities across the world and has the added benefit that left-turning cyclists can complete the turn in one stage rather than two.
