In my daily drive (or bicycle ride) to work through mostly residential neighborhoods, I encounter multiple intersections that require stopping with six stop signs, two traffic lights, and one trip over railroad tracks. A few patterns for my suburban trip and including these stops:
-The majority of the stops occur along an important north-south road in the community that is one lane each way, goes past houses of various kinds, and has a speed limit of 30 mph. Both traffic lights involve this road with only one light involving a four lane road.
-My average speed is roughly 12.5 mph. If I could go the 30 mph allowed on most of the trip and there were no stops, my trip should be more like 5 minutes long.
-Most of the stops are pretty short except for two kinds. The traffic lights can cause a wait of up to a minute and a half and the busier one can be longer if I have to wait through multiple lights. The train crossing obviously can wreak havoc with a typical trip with a stop for the train and then heavier traffic afterward as a long line goes down the road. Most of the time, I do not encounter a train and I now have a decent sense of when the passenger trains come during the morning and evening rush hours.
The average American one-way commute is now 26.9 minutes so my commute is much shorter than many. But, that time factor can obscure distances – a 20 minute commute in a more rural area is going to cover more distance than my 12 minute drive in a residential suburb and a 35 minute commute in a major city might be a different distance.
One promise I have read about involving self-driving cars is that they will be much less impeded by intersections. Because vehicles will be able to communicate with each other, stopping at a stop light for 1+ minutes or a required stop at a stop sign in light or no traffic could be limited. Removing all that stopping and starting would also be good for the environment because of reduced idling.
I assume all of the stops are there due to safety concerns and trying to keep traffic flowing in all directions (based on traffic counts, accident reports, and road and planning guidelines). But, it would be great to see in the next few decades changes to how many stops and starts vehicles must make.
The cold in the Chicago area and Midwest may have receded but the potholes have just begun:
Streets already showing signs of deterioration are vulnerable to potholes, said Adam Boeche, Mundelein’s director of public works and engineering.
“Once the snow and ice melt, the water begins to infiltrate into the base of the pavement. Then it freezes again, causing the base to heave and expand the roadway surface,” Boeche explained. “If there are already cracks in the surface, they begin to separate more, thereby losing the integrity of the pavement and forming potholes.”
Drivers and residents are encouraged to report potholes to local public works departments. People should drive slowly and cautiously when navigating streets with potholes, said Lincolnshire Public Works Director Bradford H. Woodbury…
Cepeda’s advice on avoiding potholes is simple: Keep your eyes on the road.
So if the driver in front of you is swerving, it may be because they are distracted by their cell phone and it may be because they are trying to avoid a pothole.
More broadly, I’m a little surprised that I have not heard more over the years about construction techniques or research into avoiding potholes in roadways. If we can make permeable roads and roads that can absorb pollution, why not one that is more resistant to potholes or even roads that could be self-healing? The short answer likely is that asphalt roads are relatively cheap to build and repair. At the same time, potholes can be costly and take a toll on many vehicles.
I live near a suburban intersection that regularly has people from charities standing at the stop signs to collect money. I suspect the suburb is willing to let this happen for two reasons:
- It is good for the city to allow local charities to be out in the community. This helps build good relationships between everyone. The charities then help people in the community.
- The strategy is effective. The people collecting money are in direct eye contact with possible donors. As people come to a stop, they feel obligated to drop some change into the bucket or jug. While this method likely does not lead to large sums of money being donated by a single person, it can add up quickly.
On the other hand, this is an odd way to collect money for a few reasons:
- Suburban drivers just want to get through the intersection, not be slowed down. Even if they do not give money and have an interaction with the person standing there, they have to be more careful with a person in the roadway.
- Many drivers would respond much more negatively if another party was collecting money or soliciting people at this same spot. Many communities have homeless or jobless people sitting at intersections looking for help or people selling items or services (like squeegeing a windshield without the driver asking for it).
- Having people stand in the roadway is generally not a good idea given the lack of attention paid to pedestrians.
Perhaps communities try to balance these two sides by only offering limited numbers of opportunities for charities to do this (it can’t happen every week, for example) or limiting activity to certain intersections where drivers are going slower and traffic is not impeded as much.
On the whole, this particular method is unusual and maybe only certain charities can get away with it with limited exposure to drivers.
If the single-family home offers private space in suburbia, the car offers private mobile space. The home offers a base to which the owner can retreat, the car offers the chance to travel elsewhere. Even if the single-family home is the ultimate focus of suburbia, these homes are hard to imagine without cars in the garage or driveways (usually front-facing, sometimes in the rear) or without traveling to the suburban in something other than a car. Cars and homes are intimately connected in American society.
Americans love driving (and need convincing to instead use mass transit). The suburbs require driving. The sprawling nature of suburban communities are often ill-suited for mass transit. On one hand, driving offers freedom to go where you want when you want. It is a symbol of American individualism. On a global scale, Americans have one of the highest rates of car ownership. On the other hand, owning a car has numerous costs. It is not just the obvious costs of gas, insurance, and car maintenance (and even these add up for the average owner). Additionally, critics would argue cars are a drain on community life as people can build relationships and spend money wherever their car can take them, commuting via car can take a lot of time and can limit economic mobility, road networks are costly to maintain, have negative effects on the environment, contribute to health issues through limited walking and biking, and are a menace to pedestrians and bicyclists who want to be part of the streetscape as well as are a safety threat to drivers and passengers themselves. Even with these costs, Americans persist in driving. For example, rather than push back against highways and driving in the auto-dependent Los Angeles area, officials instead focused their efforts on getting more efficient cars. The thought of major highways closing for a few days in a sprawling region creates near panic and highways can become effective sites for protests because of the number of inconvenienced drivers.
Numerous aspects of suburbia emphasize the love of cars. The single-family home would be incomplete without a garage. As homes increased in size over the decades, so did garages. The pattern of driving out of the garage at the beginning of the day and back in at the end with minimal neighborhood interaction may not characterize every home but is common enough. Many suburban single-family home are located along residential streets that are plenty wide and can handle cars traveling at decent speeds. The fast food restaurant would not be possible without cars. What is more American than going through the McDonald’s drive-thru in the midst of another suburban trip? Think of the many commercial strips all around America with fast food restaurants and strip malls (they may even not be considered aesthetically appealing by some suburbs). Similarly, the big box store – Walmart, Costco, Ikea – and shopping malls would not be possible without cars. In these spaces, hundreds of separate drivers can congregate in massive parking lots for unparalleled choice and prices. Numerous industries, let alone the automobile industry, depend on cars, vehicles, and roads.
The suburban car is part status symbol, part lifeline to the outside world. What vehicle you have matters and judging from the vehicles around me, the suburban family life is impossible without an SUV or minivan. Not being able to drive is a huge problem (sorry teenagers and some seniors). The largest category of trips involves drives between suburbs, particularly for work as jobs are spread throughout suburban regions. Additionally, the image of soccer moms persists as kids need to get to all of their activities.
It is difficult to predict how exactly cars fit into the future of suburbs. Driverless cars may mean fewer people need to own their own vehicle (those garages can then be used to store more stuff!) but being able to relax or do work rather than drive may mean people could live even further from cities. Millennials have less interested in car ownership and driving. Numerous suburbs are pursuing denser developments, particularly along railroad or transit lines, and this could limit car use in those areas and create more walkable spaces. Yet, it is hard to imagine the American suburbs without many cars and the ability to travel from a single-family home to all sorts of places.
The city of Los Angeles, known for its highways and roads, is trying to turn some of its streets into areas for fun and community activity:
There are roughly 7,500 miles of streets in Los Angeles, and Fickett Street is only one of them. But in this predominantly Latino neighborhood where parks are scarce, residents and activists have begun a design intervention to reclaim streets for civic life, kibitzing and play. From London to Los Angeles, the play street concept, known as “playing out” in England, has become an international movement of sorts, especially in low-income communities that lack green space and other amenities.
The efforts in Boyle Heights, a 6 ½-mile area bisected by six freeways, is a collaboration between Union de Vecinos, a group of neighborhood leaders, and the Kounkuey Design Initiative, or KDI, a nonprofit public interest design firm that helps underserved communities realize ideas for productive public spaces.
The Los Angeles Department of Transportation has invested $300,000 on 15 KDI-designed pilot play streets this year in Boyle Heights and Koreatown, another heavily trafficked neighborhood. Seleta Reynolds, the general manager of the LADOT, first became aware of the concept while visiting Copenhagen…
On a recent Sunday, Kounkuey unveiled its “playground in a box.” Shade structures stretched across Fickett Street, affixed to loquat trees and no-parking signs, and the plastic “wobbles” created by KDI doubled as Tilt-a-Whirls, BarcaLoungers, and formidable hurdles for teenage skateboarders. Nine-year-old Amanda Alvarado built a McMansion. “Ava, lookit!” she exclaimed to her 4-year-old sidekick in pink pom-pom slippers.
This is a clever idea for two reasons. First, it transforms what is typically a thoroughfare for cars into a space for community life. Many American neighborhoods and communities are full of roads and planning that emphasizes the efficiency of getting vehicles from Point A to Point B. Even if the effort is temporary, the transformation can be a powerful symbol. Second, it does not require long-term investments into new spaces or architecture. The road already exists. Bringing in the equipment takes some work but it is portable and can also be used elsewhere.
At the same time, this seems like an incomplete concept. It feels like a small band-aid for larger issues. As the article goes on to talk about, in a neighborhood bisected by highways, lacking green space, and pushing back against gentrification, couldn’t more be done? How about permanent parks?
A debate in Kansas City about naming a road in honor of Martin Luther King, Jr. involves asking how the name might affect people:
Some residents argue that choosing a street in a disinvested, mostly black neighborhood would perpetuate stereotypes of thoroughfares that are already named for him in other cities, and would fail to force white people to consider Dr. King’s legacy and the racism that still exists so long after his death. Others, though, say that choosing a street in a white area would be an affront to the city’s black residents and disrespectful of the fact that Dr. King fought primarily for the rights of black people…
Mr. Lucas said he leaned toward giving the name to a street where white people tend to venture more often, because it could have a greater impact there. “There’s something to be said for the fact that you need to make sure the entire community honors it, instead of saying, ‘That’s something the black folks are doing for the black folks in a black area.’ ”…
Complicating this naming fight is a simple truth: Kansas City, like much of the country, struggles with segregation.
For two years, advocates have lobbied the parks board, which oversees the city’s boulevard system, to change the name. Jean-Paul Chaurand, the board president, responded last month with a letter stating that longstanding policy has been to name streets after local residents who made significant contributions to the city. He suggested creating a commission to discuss the renaming further.
This sounds like a ready-made research question: do honorary roads affect attitudes and behaviors over time? Major cities have many such roads, in various neighborhoods, and designated at various times which would give researchers plenty of variation to work with. I wonder if such research would show minimal positive effects in a city overall (though it could be more important in particular locations, as noted in the discussion above) but then it might be argued that not naming such roads – particularly in a case like Martin Luther King, Jr. – would have negative repercussions.
See an earlier post where Illinois legislators discussed creating a Barack Obama roadway. If Reagan has a highway (the Ronald Reagan Memorial Highway in Illinois among others in the United States), shouldn’t Obama get one as well?
Here are the secrets of “those weird black tubes in the road”:
Here’s a good description of the actual operation of the tube setup from the U.S. Department of Transportation:
“Pneumatic road tube sensors send a burst of air pressure along a rubber tube when a vehicle’s tires pass over the tube. The pressure pulse closes an air switch, producing an electrical signal that is transmitted to a counter or analysis software. The pneumatic road tube sensor is portable, using lead-acid, gel, or other rechargeable batteries as a power source.”…
A single pneumatic road tube is most commonly used to simply count the number of cars on the road, as well as time the gaps between individual vehicles.
If two pneumatic road tubes are set up spaced slightly apart, the counter can track the number of axles a vehicle has to better determine each individual vehicle’s class, the direction of traffic and the speed at which vehicles are moving.
A relatively simple device to figure out how many vehicles are on the road. These traffic counts are then very helpful for additional decisions like traffic control, widening or adding to roads, and even thinking about new roadways.
