History
Saturation model
The idea that car ownership would reach a saturation level and stop growing further has been around since at least 1925 when, for example, Miller McClintock noted that " e most widely accepted estimate of the saturation point is five-to-one, that is, one automobile for every five persons". McClintock also predicted induced traffic

would reach its maximum level by about 2010, with car use showing little further growth after that point.
In a series of international comparisons starting in 1993 and continuing until his death in 2011, the American researcher Lee Schipper Leon Jay "Lee" Schipper (April 7, 1947 – August 16, 2011) was a physicist and energy efficiency expert who authored more than 100 technical papers and a number of books on energy economics and transportation. He was "often a critic of the conventi ...
and his colleagues noted that car traffic growth had slowed or ceased in a number of developed economies.
'Peak car' theory
The 'peak car' hypothesis was proposed after declines in traffic during the morning peak period were observed from the mid 1990s in some places and at a national level since about 2008. ''Local Transport Today'', a professional transport journal in the United Kingdom, reported that the number "peak car traffic" entering Britain's town and city centres during the morning peak hour
A rush hour (American English, British English) or peak hour ( Australian English) is a part of the day during which traffic congestion on roads and crowding on public transport is at its highest. Normally, this happens twice every weekday: ...

was introduced and a further 12% by 2004.[ Inbound car trip into Birmingham during the morning peak period had fallen by 29% between 1995 and 2003.]
Between June and September 2010 Professor Phil Goodwin published a series of articles in the UK professional transport press suggesting that data showed not merely a plateau in vehicle miles driven but rather a decline in overall automobile usage per capita. These articles were later compiled and updated in a journal article by Goodwin, published in 2011.

noted that "peak car use came and went n the UKat least 15 years ago, when none of us noticed". He then published articles in 2010 and 2012 suggesting that the Department's forecasts of growth were erroneous because in the UK a saturated peak level had already been reached.
In November 2010 by Millard-Ball and Schipper presented data confirming the trend in cities in eight nations: United States, Canada, Sweden, France, Germany, the United Kingdom, Japan and Australia. Newman and Kenworthy published an article in June 2011 suggesting that the effect was also valid for Australia.
By 2016, several papers have cast doubt on the peak car phenomenon, demonstrating that economic and sociodemographic factors account for most or all of the observed slowdowns. Recent statistics in the US show total vehicle-miles traveled (VMT) increasing after several years of decline, although per-capita VMT remains below its all-time high.
Proposed causes
There is speculation about causes of a decline in automobile usage. Analysts such as Newman[ as well as views expressed in the journal edited by Melia entitled ''World Transport Policy and Practice'' point to various interrelated causes. Factors include:
# Travel time budgets, a theoretical psychological limit suggesting a long term constraint on the amount of time people allocate to travel of about one hour a day. Studies using this concept (albeit not always defined in the same way) have included those of Zahavi (1974), Mogridge (1983) and Metz (2010) who suggested that saturation would naturally follow from the observation that access to destinations increased with the square of speed, but was offset by the tendency for each additional choice of destination to offer less and less extra benefit. A version was suggested by Marchetti, sometimes called 'the Marchetti Wall'; when cities become more than "one hour wide," they stop growing or they become dysfunctional, or both.]
