The first design resembles a cloverleaf interchange, but has no way to merge back onto the highway once you enter it, making it inescapable. The second interchange has off-ramps that you would normally use to change to the other highway, but in this design they simply merge back to the original highway, so you don't really have a choice in where to go. The unconventional rotary has a path that puts cars from opposite sides of the rotary onto a collision course. This is a humorous reference to particle accelerators (such as the Superconducting Super Collider) which are designed to put particles on a collision course.

Boston is a (slightly more complicated) prank in itself. A common fiction is that the streets evolved from old cowpaths; but in the 17th century they avoided swamps and marshes and followed shorelines before the original peninsula comprising the city was expanded with landfill in the 19th century. Boston's road infrastructure in general lacks a street grid. On top of that, roads change names and lose and add lanes seemingly at random.

Transcript

[Each panel depicts a highway intersection.]
The Inescapable Cloverleaf:
[Roads lead onto the rings for each leaf, but then are trapped in the circles. Minor roads also allow travel between the rings.]
The Zero-Choice Interchange:
[On and off-ramps exist, but they lead back to the same lane they disconnected from.]
The Rotary Supercollider:
[The roads lead into a traffic circle, and then a loop reverses the direction of flow so all the roads run into each other.]

Discussion

The US-67 @ IH-20 interchange in Dallas has sort of a zero-choice interchange: If you're not already on the highway, attempting to get on the highway will take you beyond the interchange. It's a mess. 108.162.221.153 05:38, 14 December 2014 (UTC)

That's not a bug, it's a feature! On-ramps within a mile or so of a major junction are the main cause for a lot of junction backups, as the paths of people limited to one lane (and slowing down) intersect with those trying to pass through and merge into 60+mph traffic. 108.162.221.87 12:04, 27 May 2016 (UTC)

From a European point of view, Boston does have a rather uniform street grid, it's not comparable to the traffic difficulties you'll get in major European cities like London, Paris, Rome, Berlin or Brussels. For many of those cities, the inner town just has to be avoided in a car. --173.245.49.136 23:56, 10 January 2015 (UTC)

what? oh yeah - the driving on the wrong side of the road thing - that would get confusing... but seriously, it's... interesting from what I can tell by Google Maps' representation of it - assuming I could discount the side of the road I'm on, and if I get a good look at the map before going out, I don't think it looks that bad.

It's not driving on the OTHER side of the road that's the issue, it just a sort of running joke with many non-Canberran Australians visiting Canberra and complaining about the (relatively large) number of roundabouts in the city. Even Parliament House is built on a massive roundabout.-Pennpenn 108.162.250.155 03:26, 30 March 2015 (UTC)

The Supercollider has a stylized "S" inscribed in a circle, as if a logo. Mountain Hikes (talk) 13:58, 25 September 2015 (UTC)
