Jarrett Walker

In the 1970s, Walker became interested in transit issues while using Portland's TriMet bus system.{{cite news |last=Green |first=Emily |date=December 6, 2011 |title=Hotseat: Jarrett Walker |work=Willamette Week |url=http://www.wweek.com/portland/article-18299-hotseat-jarrett-walker.html |url-status=live |access-date=February 21, 2020 |archive-url=https://web.archive.org/web/20190810203639/https://www.wweek.com/portland/article-18299-hotseat-jarrett-walker.html |archive-date=August 10, 2019}} He later worked as a planning intern at TriMet.{{cite news |last=Walker |first=Jarrett |date=May 11, 2012 |title=Portland: summer intern job at transit agency |work=Human Transit |url=https://humantransit.org/2012/05/portland-summer-intern-job-at-transit-agency.html |access-date=March 10, 2021}}

In 2011, Walker published Human Transit: How Clearer Thinking about Public Transit Can Enrich Our Communities and Our Lives with Island Press. In 2024, he published a revised edition that expands on his ideas of access, meaning the freedom to do things that require leaving home.{{Cite web |date= |title=Human Transit, Revised Edition |url=https://islandpress.org/books/human-transit-revised-edition |access-date=February 26, 2024 |website=Island Press |language=en}}

Walker frames discussions about public transportation in terms of an area's geometry and how it influences a transit network's ridership and coverage (also known as the "ridership-coverage trade-off").{{Cite web |url= https://t4america.org/2019/11/25/heres-what-happens-when-jarrett-walker-takes-over-your-twitter-account/ |title= Here's what happens when Jarrett Walker takes over your Twitter account |date= November 25, 2019 |access-date= February 21, 2020 |archive-date= February 21, 2020 |archive-url= https://web.archive.org/web/20200221051724/https://t4america.org/2019/11/25/heres-what-happens-when-jarrett-walker-takes-over-your-twitter-account/ |url-status= live }}{{cite book |last1=Higashide |first1=Steven |title=Better Buses, Better Cities |date=2019 |publisher=Island Press |location=Washington DC |isbn=978-1-64283-014-9 |page=24}}{{Cite web |title=Basics: The Ridership – Coverage Tradeoff |url=https://humantransit.org/2018/02/basics-the-ridership-coverage-tradeoff.html |access-date=March 25, 2024 |website=Human Transit}} He argued that an area's physical features (for example, the Bay Area's bay) significantly impact a transit network's ideal design and potential ridership.{{Cite web |title=Bay Area's Disjointed Public Transit Network Inspires a Call for Harmony |author=Patricia Leigh Brown |work=The New York Times |date=August 2, 2015 |access-date=June 4, 2020 |url=https://www.nytimes.com/2015/08/02/us/bay-areas-disjointed-public-transit-network-inspires-a-call-for-harmony.html |quote=Part of the problem is geography.

In the 2024 Revised Edition of his book Human Transit, Walker puts new emphasis on the concept of access (sometimes called accessibility) by which he means your freedom to do anything that requires leaving home.{{Cite web |title=Basics: Access, or the Wall Around Your Life |url=https://humantransit.org/basics-access-or-the-wall-around-your-life |access-date=March 25, 2024 |website=Human Transit}} His firm analyzes service change proposals not by predicting ridership — which Walker argues is unpredictable{{Cite journal|last=Walker|first=Jarrett|date=January 1, 2018|title=To Predict with Confidence, Plan for Freedom|url=https://scholarcommons.usf.edu/jpt/vol21/iss1/12|journal=Journal of Public Transportation|volume=21|issue=1|pages=119–127|doi=10.5038/2375-0901.21.1.12|issn=1077-291X|access-date=March 11, 2021|archive-date=August 19, 2018|archive-url=https://web.archive.org/web/20180819152240/http://scholarcommons.usf.edu/jpt/vol21/iss1/12/|url-status=live|doi-access=free}} — but instead by measuring how a plan expands or reduces where a person could get to in an amount of time they are likely to have in their day. He argues that while ridership is unpredictable, access analysis captures the way that the design of the network influences ridership. He also argues that access is a measure of many other things that people value, including the economic viability of the city and the experience of personal freedom.

Walker has criticized claims that modern ride-share services like Lyft and Uber are equivalent to or a potential replacement for public transit, arguing that ride-share services are much less efficient than even a relatively low-density bus service.{{Cite web |title=The Bus Is Still Best |last=Walker |first=Jarrett |work=The Atlantic |date=October 31, 2018 |access-date=June 4, 2020 |url=https://www.theatlantic.com/technology/archive/2018/10/bus-best-public-transit-cities/574399/ |quote=Visualize a low-density suburb, with requests scattered over a wide area. How many people's doors can a driver get to in an hour, including the minute or two that the customer spends grabbing their things and boarding? The intuitively obvious answer is the right one: not very many. An Eno Foundation report promoting microtransit could not cite a case study doing better than four boardings an hour of service. John Urgo, the planner of demand-responsive service for AC Transit in Oakland, California, has said that seven boardings an hour is "the best we hope to achieve." Few fixed-route buses perform that poorly. Across sprawling Silicon Valley, for example, fixed-route buses carried 12 to 45 people an hour in 2015. In a dense city such as Philadelphia, the number can exceed 80.

Walker's proposed redesigns have sometimes faced criticism from city residents, advocacy groups, or news agencies. In Dublin, Walker proposed consolidating the complex bus network into central "spines" with more frequent bus service.{{Cite news |last=Burns |first=Sarah |title=Dublin Bus plan: Designer surprised by 'very aggressive' criticism |language=en |newspaper=The Irish Times |url=https://www.irishtimes.com/news/ireland/irish-news/dublin-bus-plan-designer-surprised-by-very-aggressive-criticism-1.3642549 |access-date=March 27, 2021}} The public transit authority received over 72,000 comments from the public, of which a large portion criticized the proposal as service cuts, despite overall increases to both service frequency and geographic coverage.{{Cite news |last1=Burns |first1=Sarah |last2=Kelly |first2=Olivia |title=Final redesign of Dublin's bus network to see services rise 23% |language=en |newspaper=The Irish Times |url=https://www.irishtimes.com/news/ireland/irish-news/final-redesign-of-dublin-s-bus-network-to-see-services-rise-23-1.4363599 |access-date=March 27, 2021}}{{Cite news |title=NTA rows back on cuts to direct Dublin city bus routes |newspaper=The Irish Times |url=https://www.irishtimes.com/news/ireland/irish-news/nta-rows-back-on-cuts-to-direct-dublin-city-bus-routes-1.4059030 |url-status=live |access-date=February 21, 2020 |archive-url=https://web.archive.org/web/20191024012237/https://www.irishtimes.com/news/ireland/irish-news/nta-rows-back-on-cuts-to-direct-dublin-city-bus-routes-1.4059030 |archive-date=October 24, 2019}}{{Cite web |last=Begley |first=Dug |date=December 18, 2016 |title=Metro ridership in reverse after transit officials boasted bus system revamp would add many riders |url=https://www.houstonchronicle.com/news/houston-texas/transportation/article/Metro-ridership-in-reverse-nearly-two-years-after-10801459.php |access-date=March 27, 2021 |website=Houston Chronicle |language=en-US}} In addition, libertarian Randal O'Toole, a noted transit skeptic, has been a vocal critic of the implications of Jarrett Walker's work.{{Cite web |title=Redesigned Bus Routes Won't Save Transit |url=https://ti.org/antiplanner/?p=14790 |url-status=live |archive-url=https://web.archive.org/web/20190217034339/http://ti.org/antiplanner/?p=14790 |archive-date=February 17, 2019 |access-date=February 21, 2020}}{{Cite news |title=Is Transit Doomed in the U.S.?
