Getting to the point where most or all American drivers have safe and reliable driverless cars will take time. In the meantime, why don’t we have smart traffic lights or at least every traffic light operating with sensors?
There are several intersections near my house and work that clearly do not have sensors. You pull up in your vehicle and regardless of time of day or how many others want to go the same way as you do, you will wait a full light cycle. Some of these lights are one to one and a half minutes long. Sometimes this makes sense: one road clearly has more cars. Yet, often this full period passes with few to no cars going through the light.
But, let’s go further. I’ve also run into situations where the sensors might just be too sensitive. This occurs particularly between 9 PM and 5 AM when traffic is light on major roads. A single vehicle wanting to turn onto the major road can stop traffic. If you have a few of these on a single trip, this can be frustrating. Why not have coordinated light signals along major corridors? Cities and suburbs do not necessarily have to go to full-blown smart systems that hope to coordinate all traffic; even just doing this on a few main roads with significant amounts of traffic could help ease congestion.
Perhaps one issue is cost: what municipalities or other governments (depending on who has jurisdiction over the road) want to spend money on sensors and devices? One of the supposed benefits of driverless cars is that they will allow for more flowing traffic through coordination across vehicles. However, in that scenario the cost of less congestion is pushed to the car owners who have to purchase such a vehicle. Sensors at major intersections or at all intersections would not require anything or much from drivers. Yet, I bet you could make an argument that putting money into better intersections will be a cost savings in the long run with less time spent in traffic.
A new urban planning guide considers how driverless vehicles could transform streets:
To that end, on Monday, the National Association of City Transportation Officials, an international, 60-city organization of very serious transportation planners and engineers, published its own vision of the Promised Land, a 50-page blueprint outlining how to account for our autonomous future and build in flexible options that could result in less traffic for everyone, not just those riding on four wheels. “We don’t just need new software running on our streets—we need to update the hardware of the streets themselves,” says Janette Sadik-Khan, a former transportation head in New York City during the Bloomberg administration who now serves on the board for NACTO. “That’s why we need a new roadmap that puts humans first.”…
So what does transit heaven look like? In the future, the transportation planners suggest, vehicle lanes can be a lot thinner. Machines, after all, should be better at driving straight—and less distracted by Snapchat—than their human counterparts. That means more room in major boulevards for walking, biking, even loitering. Tiny parks might exist where parking meters once lived—no need to park self-driving taxis owned by companies, not individual drivers. In fact, vehicles might not even have their own dedicated spaces at all. “Flex zones” could be turned over to different services and vehicles for different times of day. During rush hour, there could be more lanes open to vehicles. During heavy delivery hours, there could be curb space dedicated to Amazon delivery vans (or landing delivery drones). At night, street space next to bars could be dedicated to picking up and dropping off carousers from driverless taxicabs…
“The blueprint is for building the safer future streets that cities need, where speeding is no longer an option, where cars are designed to yield and stop for pedestrians and bicyclists by default, and where people are free to cross the streets where it makes sense, rather than trek a mile to the nearest stoplight,” says Mollie Pelon, who oversees NACTO’s technology and city transportation program. Ignore the naysayers, these optimistic planners say. Autonomous vehicles don’t have to destroy the American city—they’re a shiny opportunity to rebuild it for the better.
I could imagine a number of interesting tweaks to free up more space for pedestrians, particularly since traffic can be more predictable (or at least known). At the same time, I wonder if autonomous vehicles could lead to dramatic changes in roads and cities. Imagine a community where main streets were dedicated to pedestrians and bicycles while vehicles were relegated to side streets or alleys.
Two researchers crunched the numbers and have some thoughts about when you should not own a car:
The decision for owning a vehicle or using mobility services is unique to every individual. If you purchase a highly efficient vehicle for less than $25,000 and drive it more than 15,000 miles per year until it falls apart, then you should definitely own a car if your goal is to save money.
But, if you drive less than 10,000 miles per year, face long waits in traffic, or place a high value on your time that would otherwise be spent driving, our calculations show that mobility services might be the cheaper option. Geography can also play a role—it’s not a coincidence that there have historically been so many taxi cabs in New York City, where the high cost of parking and slow pace of traffic consume time and money.
As noted before on this blog, owning a car can be a substantial part of middle-class expenses. With their physical layout, the sprawling suburbs probably then do not make much sense for not having a car. Yet, those denser suburbs for the older millennials and companies hip to them may be the true spots where suburbanites can ditch their cars. A combination of walkability, some mass transit, and car sharing in these denser suburbs could be enough to push people toward limiting car ownership.
On the other hand, perhaps driverless cars will render this all moot within a short amount of time. Within ten or twenty years, few of us will even need to own a vehicle if we just buy into a car sharing option.
Explaining the rise in traffic deaths in the last two years may be difficult to explain:
Cars may be safer than ever, but 37,461 people died on American roads that year, a 5.6 percent hike over 2015. While fatalities have dramatically declined in recent decades, this is the second straight year the number has risen. It’s too early to say why, exactly, this is happening. Researchers will need much more time with the data to figure that out. But here’s a hypothesis: It’s the economy, (crash) dummy.
“People drive more in a good economy,” says Chuck Farmer, who oversees research at the Insurance Institute for Highway Safety. “They drive to different places and for different reasons. There’s a difference between going out to a party in the middle of the night in an unfamiliar area and driving to work—that nighttime driving to a party is more risky.”…
Researchers have long known that driving deaths rise and dive with the economy and income growth. People with jobs have more reason to be on the road than the unemployed. But this increase can’t be pinned on the fact of more driving, the stats indicate. Even adjusted for miles traveled, fatalities have ticked up by 2.6 percent over 2015. You can still blame the economy, because people aren’t just driving more. They’re driving differently. Better economic condition give them the flexibility to drive for social reasons. There might be more bar visits (and drinking) and trips along unfamiliar roads (with extra time spent looking at a map on a phone).
The DOT numbers seem to confirm that drivers involved in traffic deaths were doing different things behind the wheel last year. The feds say the number people who died while not wearing seat belts climbed 4.6 percent, and that drunk driving fatalities rose 1.7 percent. Contrary to what you might expect, the numbers show distracted driving deaths dropped slightly, but experts caution against putting too much faith in such info. The numbers are based on police reports. They’re reflections of what cops are seeing at crash sites, but also of what’s in the zeitgeist at the time. It could be that first responders weren’t, for example, looking out for distracted driving last year because it wasn’t in the news as often.
Official statistics do not provide all the information we might want. In this case, the figure of interest to many will simply be the total number of deaths. Is an increase over two years enough to prompt rapid action? If so, I would imagine the regulatory structures regarding driverless cars might attract some attention. Or, do car deaths continue to be the costs we pay for having lifestyles built around driving?
Recent surveys suggest a majority of Americans don’t want to hand over their steering wheels yet:
Autonomous autos are advancing so rapidly that companies like Uber Technologies Inc. and Alphabet Inc.’s Waymo are beginning to offer robot rides to everyday consumers. But it turns out the traveling public may not be ready. A recent survey by the American Automobile Association found that more than three-quarters of Americans are afraid to ride in a self-driving car. And it’s not just Baby Boomers growing increasingly fearful of giving up the wheel to a computer, a J.D. Power study shows — it’s almost every generation.
Consumers will only become comfortable with driverless cars after they ride in them, Mary Barra, the chief executive officer of General Motors Co., said this week. The largest U.S. automaker is testing 180 self-driving Chevrolet Bolts and ultimately plans to put them in ride-hailing fleets, though it won’t say when…
Dangerous as it may be to operate cars themselves, many drivers are anxious about autonomous technology because they associate it with the fragility of electronic devices. Laptops crash and calls drop with nagging regularity. The consequence of a computerized car crash is much greater.
Americans tend to like technology: we like progress and new and exciting options. Is the fear related to safety or also connected to how Americans view driving (despite all the hours spent commuting and stuck in traffic, Americans like the freedom it offers)?
I’m guessing this fear will drop within a few years as stories of mishaps become normal (and even the occasional mishap would be safer in the long run compared to the tens of thousands of Americans killed each year in vehicles) and the technology improves. Could we also imagine a scenario where governments impose self-driving vehicles because of their improved safety?
The car of the future could be quite different but what exactly it will be is still up in the air. Will it be an electric car? We need some significant infrastructure for that to work:
But here’s the thing. As a piece of new driving technology, the Bolt totally works. But the adoption curves and take-up rates of new technologies aren’t driven simply by the efficacy of the technology in and of itself. New innovations require infrastructure to reach their full market potential. Often that infrastructure has to be built by companies other than those who build the original products. And right now, electric cars remain hindered by a massive infrastructure gap…
Tesla has dealt with the infrastructure challenge by building its own network of proprietary superchargers—stations that only Tesla owners can use. But it’s a closed system, and it is part of what makes Tesla a luxury product. Non-Tesla users are out of luck. And while some of the big automakers are establishing partnerships with charging networks, none has taken it upon itself to build the dense, easily accessible, and highly functional network of charging stations that is needed. So it’s great that the Bolt feels like it belongs in everyone’s garage. But until that gaping infrastructure gap is bridged, it won’t be in nearly as many as it could be.
And working out all the kinks of driverless cars and then making them affordable to the mass market may take a while:
Despite technological advances, accidents like these reduce consumer trust and send companies back a few steps. A true autonomous future is perhaps as far away as 50 years, considering all that needs to happen to ensure safety and prepare the average driver.
While one will see the occasional driverless car zipping tech execs around Silicon Valley, new connected cars will still be out of reach for most families.
The internal combustion engine vehicle with a human driver may prove to have quite the staying power. How about we envision the electric self-driving vehicle for all several decades down the line?
Another thought: given all that would need to be done to completely switch over to either option, could the money and time be better spent on other problems?
If and when driverless cars become the norm, how might places change?
The possibilities are dazzling. If self-driving cars lead to a significant drop in the number of vehicles on the road, parking garages could be turned into apartments or stores. Curbside parking could be converted into rainwater-collecting bio swales that help prevent sewers from backing up. Roads would narrow. Sidewalks would widen…
At IIT, such efforts crystallized in the “The Driverless City,” a 168-page book by Brown and fellow faculty members Lili Du, Laura Forlano, Ron Henderson and Jack Guthman, an adjunct professor and well-known Chicago zoning lawyer. The book serves up visions of the future that read like an update of Verne’s Victorian-era novels, which foresaw the advent of inventions such as submarines. Take this description of future commuting patterns, which is rendered in the past tense:
“On heavily trafficked arterial roads in Chicago and cities throughout the country, human driving faded away as driverless cars become more affordable and widely available. … Collisions and fender benders became rare events. … The clutter of omnipresent traffic lights gave way to smaller furnishings with embedded infrastructure that helped control the flow of vehicles.”
The book also offers a vision of how driverless cars might break down traditional barriers between street and sidewalk, nature and technology. Focusing on a proposed transformation of the South Side’s King Drive, the authors see parking spaces disappearing and vegetation sprouting in their place:
This sounds what like a number of urban planners (such as Jeff Speck in Walkable City) have been suggesting for years: the streetscape could be organized around pedestrians and social life on the street rather than on moving as many cars as efficiently as possible. Americans like their cars and many don’t seem to mind the required changes that must go with it – but this could force their hand regarding urban planning. While American communities are clearly designed with the car in mind, it is interesting that it would take a major technological advance – vehicles that can safely operate themselves – to finally tip the scales toward other street users.
More broadly, driverless cars will likely be sold to the public because of their safety but they could transform all sorts of areas.
