Big, expensive highway expansion projects are the source of a lot US transportation funding - but they aren't a silver bullet for congestion relief. In communities that were built for cars, solving traffic problems requires much more holistic problem-solving.
At 1:00, we show a bar graph of travel times on the Katy Freeway that was originally put together by City Observatory, which has covered the Katy Freeway expansion project at length:
This video was based in large part on research by Gilles Duranton and Matthew A. Turner:

Correction: At 5:12, we use Boston as an example of a successful urban highway removal project that resulted in congestion-reduction. Many of you correctly pointed out that this example isn’t quite right, because they moved several highway lanes underground. You can read more about that project here: When it comes to congestion-reduction, highway removal projects are inherently complicated, but here is more information about some of the environmental and racial justice impacts of a proposed federal plan to remove urban highways:

After the removal of the highway of I-93 and replacement with a boulevard with bicycle and bus lanes and better sidewalks in the '90s, in the 2000s, however, the tunnel of I-93 was constructed but traffic doesn't last long until Boston became the most congested city in the US.

@Nomad624 vox is being pretty disingenuous about the 62% reduction. Firstly it was a 62% reduction in vehicle hours on i-93 and other adjoining roads, which doesn't necessarily mean fewer cars, it's possible the same number of cars were just able to move faster, reducing vehicle time on the road. Secondly, if you read details about the project and it's impact on traffic, it's very clear that improvements didn't come from moving the highway, they came from improving the connections between the highway and other major arteries to make those transitions happen more smoothly and at a higher speed. So basically the 62% improvement came from making connections between roads better, not from removing a highway or reducing capacity.

I think what happens is you just don't have enough lanes. So there is a point where if you have more lanes then congestion does go down, you just have to get to that point. Even if it is 50 lanes. Or double or triple Deckers with 100 lanes.

It's actually not quite correct that there is a core of drivers that will always drive no matter what... IF there were other transport options, then a large portion of them might be able to transition away from private cars.

Still bottlenecks eventually when too many people have a common exit. Another variable to play with is to spread out the density over time.

There's a fallacy here somewhere. At the same level of congestion, a 6-lane highway still moves 50% more people per hour than a 4-lane one. Similarly, if you have zero roads you will have zero congestion because people physically can't drive. Now they can't get anywhere, but that doesn't seem to concern you, your goal is zero congestion.

I believe the U.S. traffic can’t be solved by any road systems at all. The mind set of the citizens must be changed first, you gotta find better solutions for social communities instead. Take Europe as an example, many cities have high density of people per square feet, yet most people use public transportations, bike or walk to their destinations. They also live near their work and study places regardless of their social class (upper, medium and lower class). I mean that if you had one company which staffs 10 people (manager, janitors, employees and etc..), they all must try to live near their workplace instead of living far away due to their neighborhood status and drive for hours. That’s the main problem with the U.S. American neighborhoods are built and categorized by income class rather than anything else.

I think the issue is the car is just too big for heavily populations. One car is like 5 to 10 people standing next to each other in size. Think of how many people can fit into one sub way cart compared to each one driving a car.

I lived in Vancouver, BC for almost 10 years. BC has different pricing for license plates partly based on when you're doing the bulk of your driving. I had the "pleasure vehicle" level (whatever it's called. I think it's that), where most of my driving is done outside of morning and evening rush hours. I was allowed to drive to and from work during rush hour up to 6 times a month with no penalty. It wasn't really enforced super well, but if I got caught driving to and from work more than that, I would get a pretty sizable ticket. I don't know how well this worked. In Vancouver, at least, there was always a ton of traffic, no matter the time of day (aside from overnight, I guess).

It's a little more complicated than that. If you have an accident & ICBC can prove that you're abusing the insurance category, then you'll be liable for damages & fraud.

One way to help with congestion is car pooling. Anyone who drives alone should pay a toll to drive on these busy highways.
Zak MMR 12 दिन पहले
It seems to me induced demand isn't what's going on. It's that demand was suppressed by the congestion (making the highway a less valuable choice) and the expansion was insufficient to meet to actual demand for an uncongested highway. It's not like there are infinite commuters that will keep appearing indefinitely.

Just make better public transport. Like in my country its cheeper for me than driving a car, its fast (not like driving, but in the end there is nowhere to park so I have to park further from the destination and the rest walk, so in the end it costs me the same amount of time), its clean... But i prefer walking if its max 60 min of walk (to my school its +-35min by bus, but 45min by walk) I'd rather leave home a few minutes earlier but I'll be fit.

Having lived in Houston for 15 years I believe the root of the problem is the every growing increase in population of the Houston metro area. Until the population of the area stabilizes we will just be playing catch up and never solve the problem. Furthermore, since Houston is so spread out public transportation is only an option if you happen to work downtown. It is ironic that on Earth Day there is hardly any mention of the fundamental cause of climate change, water and food shortages, and a host of other environmental issues which is an expanding population. As the population grows there is a struggle to determine where is the water, food and energy for the added people going to come from. We need to recognize that any family that has more than 2 or 3 children is part of the problem. The concept of sustainable development or production is a joke without a stable population. Unfortunately, business and politicians seem only to focus on growth. In addition, many of the places with the highest rates of population growth are less developed which further complicates the issue. Until a stable population becomes a major part of the conversation nothing will really change.

I don't usually comment, but this is hilarious: The best way to remove traffic, is to remove highways. This is sort of like Trump saying, if we don't test for COVID, there won't be any cases. What exactly is the proposed solution? Just no roads to get from here to there? This is so ludicrous. No roads, No Traffic. Absolutely genius, right? In economic terms, the solution is to reduce the demand for mass transit. I.E., less necessity to put up with traffic to get to your "job". The solution is not to reduce supply. That would create many serious problems. What about Logistics? How would destroying highways be a good thing logistically? The simplest reason that traffic is so bad is because of how our society functions. If people didn't have bills, etc. no one would put up with traffic. There are better solutions to traffic than just destroying the highways. They include less emphasis on money, and working near where you live.

What this video fails to address, is its own example of Boston. Boston, conducted the Big dig, one portion of which was to put the old freeway underground. This video fails to portray that, as it makes it seem like a freeway was then replaced with a boulevard, when in actuality, the freeway was replaced with a similarly sized, if not larger tunnel underneath that stretches the span of the old freeway, and a boulevard above.

I'm sure adding more lanes also increases congestion because of lane changes. When it's busy, every time a car changes into a new lane it makes the existing traffic slow down a bit too make room, so if you expand to a 20 lane road you must increase all the lane changes going on
MelloBreather 25 दिन पहले
I mean I get the idea of induced demand and how we should avoid giving extra incentives for people to get on the highway all the time but I don't agree with the idea of removing highways which the US federal government spent so much taxpayer's money on. I think private automobiles should work in conjunction with a good and affordable public transportation system but not sacrificing cars for buses and subways. It's just like economic growth also follows with producing more green house gas, but the solution to the problem should be finding green energy instead of reducing economic growth.
Just tax more on people with private cars to fund the Public Transportation System.

At 1:02, there is mention of a simple economic theory that explains why building more lanes does not reduce congestion. This theory is the law of demand and supply. More highways (supply) leads to more cars taking to the roads (demand), so congestion never goes away. While this is interesting and in large part accurate, this is actually NOT the main reason why more lanes and highways fail to reduce congestion in urban centers. The real reason hinges on a different economic concept known as output. In other words, reducing congestion should address the most critical bottleneck. And the bottleneck was never "how many cars can I have on a highway" but instead at what rate can I get them to exit the highway. In most infrastructure projects, adding lanes to highways essentially equates to adding "storage capacity" to the highway, which is absolutely nonsensical. The real issue is with the number of exits and their respective outputs, which are the only elements that really require fixing. Highways with 10, 15, etc. lanes across are a complete aberration and waste of capital. Now on incentives and highway removal, this is something that can be accepted for aesthetical reasons (e.g. Boston where it was buried) or if maintenance costs spiral out of control. But it really is a cowardly decision when so many other superior options to incentivize exist, they only require more courage. That being said, there is no argument that building highways and adding lanes the way it's been done the past few decades is lazy and aggravates America's already sub-par infrastructure.

I lived within walking distance of this interchange for about 20 years. Then, I became head engineer for Atlanta for 20 years. This is an excellent video for the layperson, or even the expert. I've built many $ 100M+ Interchanges, that when finished, were already obsolete when they were opened. I am proud of one thing: That I was as influential as anybody in building Atlantic Station in midtown Atlanta, which is a true live, work, and play community.

It is sad to see a short documentary about traffic congestion and hear the final frase: "If you build it, they will come". Looks as if people having to go to work far from their homes are the guilty ones. Of course a highway expansion is built for more and more people in cars. But, what comes first? The demand that generates more infrastructure, or, is the infrastruture that generates demand? Should people stop living far from their jobs and move downtown? Should people stop getting financially better? Should people stop buying cars? Definitely there is not only one and/or easy solution. Some actions we can take, and government policies may be: decentralization of (commercial and administrative) working areas, creating new decentralize workplaces. More, and more, and better trains and metros (when possible underground), a slight change in the US addiction for big cars, more comfortable buses. And, more recently, coworking spaces and offices, more home-schooling, and, the newest, home-office. In a near future, the constant people's movements made by autonomous vehicles, or, autonomous aerial drones. If we do it, we wil use it!
