There's a slight inaccuracy in that diagram. While NJT does (via a short stint on I-295) intersect I-95 in Delaware on the southern end, the northern end has a rather more roundabout connection. I-95 continues up as a beltway around Trenton. But the beltway continues as I-295, which turns south and parallels the NJ Turnpike. If you're trying to go north on I-95, you end up heading south instead for ~7mi and then needing a ~7mi stint on I-195 to continue north.



This is correct; I knew it but didn't try to illustrate it for simplicity.


i.e., highways in Jersey are a quagmire of poor planning.

Actually, that applies to pretty much all roads—not just highways.


At least a lot of our roads, including city roads, got to be planned at all - still better than the mazes of very narrow, disorganized roads established hundreds of years ago you get in very old locations in Europe, particularly old cities. At least this is the impression I've gotten reading some accounts on the subject online - can't vouch for it 100%.


Just imagine what our planning will look like in one or two hundred years (or even 30-40 years). I would bet those more walk-able and bike-able cities will look a lot more attractive...


I don't see self-driving cars/pods making better roads not be a benefit unless they're airborne.


Current planning assumes a lot of parking is required. Streets allow parking on the sides, access routes are optimized for cars, every business wants to be as close as possible to street, etc.

I also think the shifts coming in transportation will be a lot more than an "automated uber". There will likely be a lot of automated carpooling and carpool discovery along the line of ad-hoc ride-sharing discovery. Bottom-line, I assume there will be a lot less parked hunks of metal in city centers, which will itself alter what an efficient layout entails.

The entire US is designed around personal automobile ownership to an incredible degree. Anything that affects that one way or another drastically changes optimal design layout for both residential and commercial planning.

As a simple example of this, if you've ever driven down a corridor of highway or an arterial route that is one strip mall after another behind parking lots, imagine how that changes is a large chunk of people are no longer driving their own cars leisurely, but instead hiring transport to a specific point. Road visibility is much less important. Parking lots in front are mostly superfluous. Basically, walk-able downtown areas and enclosed malls may see (and I think already are seeing) a resurgence.
