[edit] Merger with other similar pages
I expanded the induced traffic page considerably, before noticing that there were other pages for induced travel demand and induced demand. Since they all seem to be saying pretty much the same thing, they should probably be merged into one (I suggest this one).

Merge is now complete.

I'm concerned about not having induced traffic as its own entry, because it's really not the same thing as induced demand, which is a broader economic concept. Induced traffic has specific real-world policy implications. The result of the merge has been that induced travel demand and induced traffic are given remarkable prominence in the overall concept. There are other forms of induced demand, such as demand for in the US for petrol, food, and certain utilities, that are generated by inflated supply -- they have differenet policy implications. If anyone later edits this article to reduce it's traffic focus, as they would perhaps be entitled to do, we might have to re-create induced travel and induced traffic demand.

I did consider that, but since the previous induced demand article covered broadly the same topics, I thought it best to merge them. I understand the problem though - but I would suggest recreating just one of those additional pages rather than both, if necessary. Dave A 10:07, 14 April 2006 (UTC)
== Cut from freeway article == (NPOV anyone) dml In the Atlanta metro area, for example, the former governor of Georgia proposed a massive 210-mile (340km) expressway encircling the suburbs, costing billions of dollars, and destroying dozens of rural farms and exurban homes (potentially hundreds if development continued in its eventual path). Some equated it to heart bypass surgery (in this case, Atlanta's original Perimeter, Interstate 285), with the patient ignoring warnings and failing to do anything to prevent it from happening again. The opponents of the expansion won out when a new governor was elected in late 2002, but it underscored the destruction which occurs anywhere with such freeways, frequently including a legacy of urban blight and suburban sprawl.
I think the articles need to be separate here, the induced travel demand should be on its own page, and induced demand should be general, not including specific examples but rather referencing them. Jamie Q
Of course, building new roads can actually decrease traffic flow (Braess' Paradox). PML.
Braess Paradox doesn't say capacity decreases flow, it says new roads under very specific circumstances, increase travel time. (By extension, with elastic demand, demand may ultimately drop, but I think Braess's paper assumed fixed demand. someone ought to write it out ... dml
[edit] terminology on traffic: induced, generated, diverted
I see several terms used in development documents (generated, induced, diverted traffic), and I would like to suggest that some discussion of the definitions, distinctions and approaches to quantifying these would be helpful. Illustrations or examples might strengthen the discussion. —The preceding unsigned comment was added by 202.79.62.18 (talk) 04:28, 27 March 2007 (UTC).
