Editing Induced demand (section)

===Definitions===
According to ''[[CityLab (web magazine)|CityLab]]'':

<blockquote>Induced demand is a catch-all term used for a variety of interconnected effects that cause new roads to quickly fill to capacity. In rapidly growing areas where roads were not designed for the current population, there may be significant latent demand for new road capacity, which causes a flood of new drivers to immediately take to the freeway once the new lanes are open, quickly congesting them again. {{parabr}}But these individuals were presumably already living nearby; how did they get around before the expansion? They may have taken alternative modes of transport, travelled at off-peak hours, or not made those trips at all. That’s why latent demand can be difficult to disentangle from generated demand—the new traffic that is a direct result of the new capacity. (Some researchers try to isolate generated demand as the sole effect of induced demand.)<ref name=benjamin /></blockquote>

The technical distinction between the two terms, which are often used interchangeably, is that latent demand is travel that cannot be realised because of constraints.  It is thus "pent-up".  Induced demand is demand that has been realised, or "generated", by improvements made to transportation infrastructure.  Thus, induced demand generates the traffic that had been "pent-up" as latent demand.<ref>[[Patricia Mokhtarian|Mokhtarian, Patricia L.]] (ndg) [http://www.dot.ca.gov/researchconn%/past_speakers%/DrMokhtarian/induced_demand_powerpoint.ppt "Understanding the Concept of Latent Demand in Traffic"] {{Webarchive|url=https://web.archive.org/web/20200611224559/https://www.dot.ca.gov/researchconn%/past_speakers%/DrMokhtarian/induced_demand_powerpoint.ppt |date=2020-06-11 }} State of California Department of Transportation</ref><ref>{{cite journal |last1=Clifton |first1=Kelly J. |last2=Moura |first2=Filipe |title=Conceptual Framework for Understanding Latent Demand: Accounting for Unrealized Activities and Travel |url=https://www.researchgate.net/publication/318693342 |journal=Transportation Research Record: Journal of the Transportation Research Board |date=January 2017 |volume=2668 |issue=1 |pages=78–83 |doi=10.3141/2668-08|s2cid=157228080 }}</ref><ref>Rodrigue, Jean-Paul (2016) [https://transportgeography.org/?page_id=186 "Transportation as a Derived Demand"] ''The Geography of Transport Systems''</ref><ref>{{cite book |last=Cervero |first=Robert |author-link=Robert Cervero |chapter-url=https://escholarship.org/content/qt5pj337gw/qt5pj337gw.pdf |chapter=Induced Demand: An Urban and Metropolitan Perspective |pages=55–73 |date=March 2001 |publication-date=2002 |title=Working Together to Address Induced Demand: Proceedings of a Forum |publisher=[[Eno Transportation Foundation]] |publication-place=Washington, DC |isbn=978-0971817548 }}</ref>
