Why expensive road and highway widening ALWAYS fails to reduce traffic congestion. Traffic never gets better for very long, & it commonly ends up worse. And yet “fixing congestion” is ALWAYS the stated reason for spending all that public money on widenings. #InducedDemand ggwash.org/view/97803/w...

“We found there’s this perfect one-to-one relationship. If a city increased its road capacity by 10% then driving in that city went up by 10%.” Still one of the best articles on why building wider roads leads to more cars stuck in the same congestion.

“The phenomenon is known as induced demand. The result is an endless cycle in which congestion leads to highway expansion, which invites more trips, which brings back traffic…The pattern is so inevitable that economists have dubbed it the iron law of congestion.” Via @[email protected] #InducedDemand

Lower Thames Crossing has higher costs per mile than HS2
"Reeves and Alexander are both keen to press ahead with the project, which they have said is “vital” and will ease congestion on the M25.
However, the DfT confirmed it has yet to publish an “outline business case”, which would usually be produced before officials embark on large-scale works."
Bro just one more lane bro. One more lane will fix the traffic bro.

Oh, and of course, I knew once #AmazonCorp announced plans to build a warehouse in #GorhamME, the #GorhamConnector would rear its ugly head again... And even though #JanetMills' brother #PeterMills is no longer in charge of #MDOT doesn't mean the new director won't be pushing this... Instead of a light rail system or rapid bus transit on the existing roads (and / or safer bike lanes. I knew friends who used to bike from Gorham to Portland, but it got too dangerous because of a lack of dedicated bike lanes and speeders).
#MDOT will launch new examination of traffic issues west of Portland
The state study will focus on Gorham, #ScarboroughME, #SouthPortlandME and #WestbrookME.
Robert Lowell, April 22, 2026
Excerpt: "The announcement of the new study comes just days before Amazon goes to the Gorham Planning Board on May 4, seeking approval for a warehouse and distribution center on Main Street (Route 25). Traffic will likely be one issue fueling concerns about the Amazon project.
"The study also comes in the aftermath of plans the Maine Turnpike Authority shelved last year for a four-lane toll road connector to Gorham. The connector was aimed at reducing commuter rush-hour traffic in the routes 22 and 114 commuter corridor [which the #Maine Legislature failed to make go away!]
"A connector would have linked the roundabout at South Street (Route 114) and the southerly end of Gorham’s Bernard Rines Bypass with the turnpike’s Exit 45 in South Portland. The connector proposal was met with a public outcry because it called for cutting a swath through #SmilingHillFarm in #WestbrookME."

I’ll make this VERY clear — if you don’t understand very well critical truths like #InducedDemand (aka the Irrefutable Law of Congestion) and its twin truth #JevonsParadox, you are not qualified to make transportation-related decisions affecting cities. And your profession will make cities worse.

The amount of money local governments spend on putting in and ripping out infrastructure boggles my mind.
"The council said the proposed changes would “introduce expanded capacity for vehicles travelling towards the town centre” and “pave the way” for an already-approved new bus lane on London Road"
We need a sexier way to say "Induced Demand". Something like, "People use what they're given".

Traffic Jam? Blame 'Induced Demand.' - Bloomberg
https://www.bloomberg.com/news/articles/2018-09-06/traffic-jam-blame-induced-demandWhen traffic-clogged highways are expanded, new drivers quickly materialize to fill them. What gives? Here’s how “#induceddemand” works.
