If You Think Adding That Extra Lane Will Reduce Traffic Congestion - You’d Be Wrong
A recent study of 100 US cities found that — between 1993 to 2017 — billions were spent to expand highway capacities by 42% but, instead of reducing congestion, traffic delays actual went up 144%!
It’s Memorial Day, and millions of Americans are on the highways.
You’d think that if your freeway is clogged up every rush hour, adding an extra lane would reduce the congestion. You’d be wrong.
And an uprising against Oregon state government plans to widen the I-5 freeway here in Portland may end up changing how cities around the country decide to use the hundreds of billions of dollars in highway funds coming to them from the Infrastructure Investment and Jobs Act.
A recent study of 100 US cities found that — between 1993 and 2017 — billions were spent to expand highway systems’ capacities by 42 percent, far faster than the cities were growing population-wise. But instead of reducing congestion, traffic delays actually went up by 144 percent.
The key to understanding this phenomenon is something called “induced demand.” Basically, it’s the idea that when you offer a population something nice, lots of people show up to use it.
It’s sort of like supply-side economics, but in a rational version that actually makes sense.
Aaron Brown of NoMoreFreewaysPDX.com described induced demand on my radio/TV program as being like when Ben & Jerry’s offers free ice cream and suddenly a quiet storefront area has a line around the block. When freeways are expanded, more people decide to use them, producing even more congestion.
The Rocky Mountain Institute, along with the NRDC and four other environmental groups has even put online an extraordinarily detailed induced demand calculator with databases for cities all around the country.
Thirty percent of America’s greenhouse gas emissions come from vehicles and, for the city of Portland (like many cities), it’s 40 percent.
Widening our highways will only draw more cars onto the road and increase our greenhouse gas output, which has become the basis of a lawsuit against the Oregon Department of Transportation (ODOT) by NoMoreFreeways and aligned groups.
Young Portland activists had organized a Youth versus ODOT Instagram site, aligned with the Portland Sunrise movement, and there were weekly protests at ODOT offices by local high school students and others.
And they had an impact. As Bloomberg News noted:
“On Jan 18, the Federal Highway Administration (FHWA) rescinded a key approval of the controversial highway widening that’s been a prime target of the young protesters, the Rose Quarter Improvement Project along Portland’s Interstate 5. FWHA also requested that the state redo its environmental study.”
Environmental groups and activists concerned with the future livability of their cities are taking notice, and Colorado is also leading the way in now requiring that environmental issues be considered in all transportation infrastructure decisions.
Meanwhile, there’s a huge trend of cities around the world taking steps to reduce their own car burdens: from London to Bogota to Beijing, driving lanes are being replaced by bike lanes, parts of city centers are going pedestrian-only, and tolls or fees are being charged for entry into or driving within a city.
Here in America, decisions are being made about how to spend the hundreds of billions coming to states in the new highway legislation, but it’s becoming a war: the auto, tire, and fossil fuel industries are large and well financed.
Since five Republicans on the Supreme Court legalized political bribery with Citizens United in 2010, those industries are able to pour unlimited amounts of cash down the throats of state-level politicians all across the nation.
And now that hedge funds and billionaire investors have bought up or killed off so many of America’s local newspapers, that highway industry’s legal bribery (“lobbying” and “contributions”) probably won’t even be reported on in local media.
Meanwhile, the industry of companies that manufacture mass transit vehicles like buses, streetcars, and subway systems is relatively small, specialized, and doesn’t have an army of lobbyists or hundreds of millions for now-legalized political bribes.
It’s going to be a hell of a fight over the next decade or two, and our local voices could be the factor that decides whether our polluting highways are expanded or, instead, that money goes to bike lanes, public spaces, and mass transit.
Now is the time to pay attention and get active to make your community a more livable place. Tag, you’re it!
