Talk:Street hierarchy

Merger Discussion
Request received to merge articles: Hierarchy of roads to here; dated June 2015. Rationale: I think that both of the articles are about a similar topic and they have similar information. Bubby33 (talk) 14:00, 26 June 2015 (UTC)
 * Don't Merge While they have similar names, Street Hierarchy and Hierarchy of Roads are completely different subjects. The former is a system of urban (or rather suburban) planning and the latter is a system of classifying roads. To merge the two would be completely nonsensical. -Lamarcus (talk) 21:37, 11 January 2009 (UTC)

what the hell is "TND"
the abbreviation "TND" is used repetitively throughout the article, yet I can't find a single reference to what the hell "TND" stands for. — Preceding unsigned comment added by 75.38.142.214 (talk) 10:36, 18 February 2012 (UTC)

Less street length or more?
In the Financial costs section, there is this sentence:
 * Some planners and economists consider the street hierarchy to be financially wasteful, since it requires more miles of street to be laid than a grid plan to serve a much smaller population.

But then there's this, in the same section:
 * Studies show that regular, undifferentiated grid patterns generally incur infrastructure costs about 20 to 30 percent higher than the discontinuous hiererchical street patterns, reflecting an analogous street length increase.

The first says hierarchy produces more street length, the second says grid produces more street length. So which is it? C xong (talk) 00:10, 7 February 2014 (UTC)
