Maybe we should make a glossary of the most confusing roadgeek terms on the webpage...
(Note: should I ask this here? :confused: :confused: :confused:)
At one time, we had a MTR FAQ, that defined oft-used terms and acronyms (BGS, 3di, "green" interstate, etc.), explained numbering oddities like I-238 and US 400-412-425, and also (IIRC) listed a number of highway-related websites. Marc Fannin was the proprietor, and I want to think Sandor Gulyas (if he's still alive, he blocked me on Facebook for some reason) had a part in it as well.
There are a lot of terms that have come into vogue since MTR's heyday (DDI for one) that might be suitable for inclusion in some sort of updated FAQ. And instead of a list of websites, a list of road-related Facebook groups might also be relevant, since they're proliferating at a rapid rate.
To be included: 85th percentile, AASHTO, Alanland, all-electronic tolling, APL, Arialveticverstesk, Breezewood, Bud Shuster, business loop, business spur, button copy, Calrog, Clearview, clinch, closed toll system, cloverleaf interchange, concurrency, DDI, doghouse, FHWA, FritzOwl (verb), FYA, gore, HAWK signal, I-238, I-366, Jersey freeway, kerning, Michigan left, mileage-based exit numbering, modern roundabout, mtr, multiplex, MUTCD, New England route, NIMBY, NMSL, non-reflective sign, open toll system, overlap, permissive green, parclo, protected green, Rand McNally, red light camera / revenue camera, RIRO, roadgeek, secondary state route, sequential exit numbering, Series A-F, shield error, SPUI, stack interchange, TOTSO, trumpet interchange, unisign, Usenet, VMS
Does this count?

RIRO
I have no clue what that means. All the more reason to create one of these glossaries, though.

Right in- Right out
A type of basic interchange on a freeway that involves a basic off ramp to a side street (typically a frontage road) and a on-ramp from that frontage road.

And I've been pondering if right-hand drive countries have LILOs......
