For critics of widening projects, the prime example of induced demand is the Katy Freeway in Houston, one of the widest highways in the world with 26 lanes.

Immediately after Katy’s last expansion, in 2008, the project was hailed as a success. But within five years, peak hour travel times on the freeway were longer than before the expansion.

Matt Turner, an economics professor at Brown University and co-author of the 2009 study on congestion, said adding lanes is a fine solution if the goal is to get more cars on the road. But most highway expansion projects, including those in progress in Texas, cite reducing traffic as a primary goal.

“If you keep adding lanes because you want to reduce traffic congestion, you have to be really determined not to learn from history,” Dr. Turner said.

    Yup. Been plenty of studies to show that increasing lanes only alleviates traffic in the short term and long term only makes it worse. Better to spend money on trains and busses that actually work and get people where they need to go with minimal hassle and a reasonable cost than to do this crap.

        I don’t necessarily disagree that it costs more, I have no idea but it seems logical to me that it would. However, even if it is cheaper, public transit solutions also have maintenance.

          Far less maintenance, and it’s generally directly supported by rider fares instead of petitioning for government tax money.

          Also the density of passengers on transit justifies the costs. 90%+ of all cars have a single person, whereas transit is on average magnitudes more. On that basis alone transit is far far cheaper.

            Fares alone do not pay the bills. Buses are always subsidized (which is totally fine IMO. Every fine metro area has a good transit system, and it should be affordable to all who would want to use it.)

              True enough. But my point still stands that there are fares that are collected that help offset operational and maintenance costs.

              It’s still cheaper than maintaining huge roadways.

      Trains predate cars and busses have always been with us since the car. People have voted – with their cars.

      The Interstate Highway System started in the 1950s. Population has more than doubled since then. Of course, we have more traffic, we have more people!

    This is because the extra lane allows demand to change. It is not congested so people feel ok building and moving to further out suburbs. This continues until demand has increased to cause delays.

    Note that Houston and Paris have about the same population. Paris is 1/3 the size. They are actually removing a lane from their loop highway and planting trees, and turning another lane into busses only. Only considering transportation, I would much rather live in Paris.

                I had to drive to Houston now and then it was a miserable experience, and made me bitter of the whole Americana road trip thing.

                That said, on last trip, we went somewhere down to Sant Jacinto (?) and I’ll gladly live there. I did had some delicious crawfish that later vomited somewhere along the I-10 East freeway.

      But what options do you have in Houston, compared to Paris?

      You can’t just not widen roads but instead

      — less sprawl - places to live closer to each other and to destinations

      – useful transit or short distance commute options

      – remove bottlenecks

      These are a lot harder to do, and I don’t imagine Houston even considered it

        Investing is public transport can be as hard or as easy as you want it to be. Sure building a full on subterranean high density metro system might be the utopia, but actually developing a high frequency, high quality bus route with dedicated bus lanes can be low cost and hugely increase the volume of people carried Vs the lane you took from cars.
        Compliment this with docking cycle rental schemes, and some dedicated cycle infrastructure and you can transform how a big chunk of people get to work …you start to win back the city from one which is built around cars and instead making it a city for people.

          In Texas, and most of the places I know of, people won’t ride the bus, or the bike. When it’s August and the high temp for the day is 108, with 65% relative humidity, everybody wants to get in their car with the AC blowing directly on them, and be comfortable.

          In my experience, every public bus I’ve been on has been miserable.

          Luckily I was a typical self-centered teenager, so I was pretty good at being oblivious and ignoring what was going on around me. It also helped that I had very strong parents who worked tirelessly to make it as seamless/normal for my siblings and me haha.

          Well hopefully they will come up with a solution that isn’t just adding more lanes! Don’t have a lot of hope for Texas and public transit these days, but I feel like y’all would be prime candidates for high speed rail between some of your cities.

        Oh absolutely. A few years ago someone did just that because they were about to miss their exit. I slammed on my breaks and it caused 8 cars to crash. I wasn’t found at fault, but because I was the first car to stop, I had to deal with 8 different insurances from all the people involved… it was such a pain. The whole thing took around 4 months to settle all the claims and get my car fixed.

            It’s not an exit road. The service road is a parallel road to a highway that contains all the turns with occasional on/off ramps into the highway. It’s actually a pretty efficient design, as it reduces the amount of on/off ramps needed. Similar design style is local vs express lanes in some highways.

            Tl;dr less ramps = less slowdowns

    I thought it was common knowledge of the only way to reduce traffic is to reduce demand on roads, eg more expensive gas and tolls etc.

    If you add another lane to the highway you’re just gonna attract more people and make it worse.

        I agree. In addition to impacting the poor in towns and cities, raising gas prices also has an even larger impact on people in more rural areas where everything is spread out. We do most of our grocery shopping in the next town over, which is 15 miles away, with basically nothing in between. Sure it still takes only 15-20 minutes to get anywhere we want to go, but those minutes are a lot more miles out here compared to driving 15-20 minutes to go a shorter distance I’m a city.

        Within towns and cities, infrastructure should be built for people first, not cars, so as to make it easier and more pleasant to navigate a city by foot, bike, or public transit. It drives me crazy how pedestrian hostile most towns are. I’d like to see the design paradigm flipped.

      Switch demand for congestion and there are different solutions.

      1. Adjust off ramps that back up onto the highway, these cause congestion and indicate the downstream artery is too small for demand.
      2. Reduce average lanes to off ramps, each lane change adds braking slowing traffic
      3. Enforce and educate people to merge properly, obliterate people who merge too late out of selfishness with a space laser. Zipper or die.
      4. Increase carpooling and transit to the point it’s actually usable. In practice this means making your local council commute by transit only.

        Yeah, traffic congestion is a lot more complex than it seems. If you alleviate one bottleneck, you can create 15 more (because now more traffic flows through the “fixed” area, stressing everything else) where some of those new ones interact with each other in a way that slows traffic more than the original bottleneck did.

        You need to consider the endpoints as well as the middle. If you make it easier for people to get to their destination and off the road, then traffic will improve. Problem is, destinations are all over the place, so even that can end up causing more congestion if it also enables higher throughput that other roads it feeds into can’t handle.

        Mass transit experiences the same thing. Not to say that there’s no point in emphasizing it, just that it won’t get rid of the problem entirely.

      You can reduce traffic with more lanes, but not just willy nilly. They need to be carefully planned and managed while limiting lane changes.

      But a lot of the time, they won’t. The issue usually comes from people wanting to change lanes while others are merging on. In high traffic areas, lane changes will slow the traffic down while increasing the risk of an accident. Making alternatives such as different routes, other modes of transportation, or reducing the need for traveling usually work better in cities.

        Not all of them. If someone tries to ram you and you get off on the wrong exit to avoid the crazy person at 5pm on a Tuesday you can lose an hour and a half of your life over a distance of 7 miles.

        Don’t ask how I know.

          Oh I’m well aware. I missed an exit once so I just kept going, and the next one happened to be one of the few that was just a winding road and took me far away.

      Exactly this! It’s especially terrifying to drive here Friday and Saturday nights and during heavy rains. You’re also expected to go 15-20 over the speed limit and yeah, idiots will absolutely speed-cross from the furthest lane to their exit without giving a f*ck about anyone else.
