I know there is a claim this is so , see , I don't believe it, and believe the word appeared much earlier than 1980. Another reference has  it coined in 1971 in New York. New York, with its grid network is a logical place for the word to originate, more evidence here would help. Will reformat article.

text: I would have thought "gridlock" was in use prior to 1980, as well, but I definitely would not know firsthand, having not even been born then; and everything coming up on a search indicates it is indeed from the 1980's.  --Thisisbossi 15:53, 10 December 2006 (UTC)

message: While it mentions the less precise uses for the term, this article is very specifically about the type of gridlock caused by intersection blocking or close freeway ramps, not just traffic jams in general.  None of the three examples seems to be particularly relevant to the rest of the article, and they should probably be moved to Traffic jam (the China and Brazil paragraphs are already there).  — Preceding unsigned comment added by Andthendougsaid (talk • contribs) 16:16, 28 August 2011 (UTC)

message: The "See also" section links to Roadway air dispersion modeling. I don't quite see how that is related; was the intent to say that most roadway air dispersion models take gridlock as an input variable? Or is it okay for me to remove the link? --SoledadKabocha (talk) 19:13, 20 November 2012 (UTC)

message: Another form of severe congestion that can be as bad as gridlock and therefore might be called gridlock, although as explained here does not fit the traditional meaning is what I call left turn gridlock. Basically, it's where when road A with very heavy traffic gets the red light, the next thing is for road B to get left turn arrows. If the traffic that made the light on Road A is slow enough, the left turners and subsequent right turners (when road be turns green after the arrows) can fill all the space that appeared on road A, beyond the light, after turning red. This is not purely theoretical. This occasionally happens and often nearly happens on such roads as US 1 in Florida over a 10-mile stretch from the southern terminus of Interstate 95 to about Ludlam Road.
