The Lockheed Martin F-35 Lightning II is a family of single-seat, single-engine, all-weather stealth multirole fighters. The fifth-generation combat aircraft is designed to perform ground-attack and air-superiority missions. It has three main models: the F-35A conventional takeoff and landing (CTOL) variant, the F-35B short take-off and vertical-landing (STOVL) variant, and the F-35C carrier-based catapult-assisted take-off but arrested recovery (CATOBAR) variant. The F-35 descends from the Lockheed Martin X-35, the winning design of the Joint Strike Fighter (JSF) program. It is built by Lockheed and many subcontractors, including Northrop Grumman, Pratt & Whitney, and BAE Systems.

The United States principally funds F-35 development, with additional funding from other NATO members and close U.S. allies, including the United Kingdom, Italy, Australia, Canada, Norway, Denmark, the Netherlands, and Turkey. These funders generally receive subcontracts to manufacture components for the aircraft; for example, Turkey is the sole supplier of several F-35 parts. Several other countries have ordered, or are considering ordering, the aircraft.

Bargain-hunting robocars could spell the end for downtown parking – cities need to plan ahead now


Imagine a scene from the near-future: You get dropped off downtown by a driverless car. You slam the door and head into your office or appointment. But then where does the autonomous vehicle go?

It’s a question that cities would be wise to consider now. Self-driving cars may be on the roads within the next decade or two.

Automakers and specialized startups alike are aggressively developing automated vehicles (AVs), while government agencies explore ways to reduce regulatory barriers. Ride-hailing companies such as Lyft and Uber plan to operate some AVs, but others could become private robotaxis that drop owners off wherever they like and pick them up later.

Without policies to encourage sharing, it’s possible there could be many private AVs on the road. We are civil and environmental engineers who collaborated with Chris Hendrickson, director of Carnegie Mellon’s Traffic21 Institute, to examine the potential effects of private AVs on cities.

Using Seattle as a case study, our analysis suggests that one of the biggest effects of AV technology may be on parking, as AVs leave expensive downtown spots behind in favor of cheaper parking outside the city center.

Parking has a big footprint – and brings big bucks

Parking takes up a lot of land in cities.

Researchers at UCLA estimated that about 5% to 8% of urban land is devoted to curb parking. They estimated that the parking coverage – the ratio of parking area to total land area – in downtown Los Angeles and Houston are about 81% and 57%, respectively.

A 2018 parking study done by the Mortgage Bankers Association found that Seattle’s parking density of 29 parking stalls per acre of land is twice its population density of 13 people per acre.

Because driverless cars could park outside urban cores to avoid the higher parking charges downtown, they might considerably affect urban land use.

And there are potentially big fiscal consequences. Many cities gather a substantial amount of money from parking-related activities, with the 25 largest cities, collectively, generating US$1.5 billion in total revenue from parking fees and taxes in 2016.

In Seattle, for instance, annual revenues from parking meters total about $37 million. In addition, Seattle also collects $39 million and $21 million in annual revenues from commercial parking lot taxes and parking fines, respectively.

Lower demand for parking could mean these funds – traditionally used for city operations including education, cultural resources and libraries – will need to be replaced through other sources of revenue.

Simulating a city with driverless cars

To gauge the potential effects of private AVs on parking, we used Seattle as a case study because data on all its off-street parking lots is available. We looked at factors including energy use, emissions, parking revenue and vehicle miles traveled (VMT), a key statistic used by traffic engineers to measure travel demand.

Our team obtained data from the Puget Sound Region Council on the daily occupancy and parking prices of all paid off-street parking garages and lots in downtown Seattle. We went on to identify areas outside of the downtown area with many unrestricted parking spaces, where vehicles can currently park free of charge during the day.

The model assumed AVs would rather travel long distances for free parking (green) than park in a paid parking lot (red), since this minimizes cost to the user.
Harper et al (2018), CC BY-ND

Then we modeled privately owned AVs searching for cheaper parking, where each vehicle makes parking decisions based on availability and total cost, including both parking fees and all operational costs of the round trip to the parking space. Each AV’s objective is to minimize cost. An AV would not become frustrated sitting in congestion or cruising to find an open curb space, whereas a human driver would.

We varied the operating costs of AVs per mile across a range of values, to understand how future changes either in improved technology or imposed per mile taxes might affect the results.

More miles traveled, fewer parking garages?

We considered a range of possible adoption rates for private AVs, from a point when few high-income early adopters have AVs to total market penetration.

At low penetration rates – where anywhere from 5 to 50 percent of all cars traditionally parked downtown become automated – AVs are usually able to obtain their choice of parking space. In most cases, these are in free parking zones closest to where they drop passengers off downtown.

As more AVs come online, these free parking spaces closest to the downtown area fill up and cars must travel longer distances to obtain cheap parking. As market penetration rates rise, each vehicle would travel additional round trip miles in its quest for inexpensive parking.

With lower numbers of AVs on the road, this would have negligible impacts on the overall total miles traveled by cars in the Seattle region. But if all private cars parking downtown were AVs, the total daily miles traveled by cars in Seattle would increase by about 2.5%, with each AV traveling an additional 8.5 miles each day on average. That change, even if it sounds small, could cause congestion along heavily traveled routes depending on the time day and the mix of human-driven vehicles on the road.

Our simulation shows that there is enough free parking just outside downtown Seattle that AVs would no longer choose to park in downtown lots. At current prices it’s more economical to travel for free parking than to park in a paid lot.

Some private AV owners may rent out their car during the day as a ride-hailing service, but for others it might make financial sense to send their car home during the day and have it pick them up later. That would further increase overall vehicle miles traveled.

No more parking downtown?

As AVs leave downtown, parking lot revenues could decline to the point where owning a parking lot or garage would no longer be economically viable. This presents both challenges and opportunities for cities. Cities could lose a substantial amount of annual parking revenue in a future with more AVs.

We see a few ways that cities could strategically adapt parking requirements to prepare for additional travel by self-driving cars.

For example, cities could implement congestion pricing: a fee or tax paid by users to enter the urban core of the city. They could encourage more public and active transportation, like biking and walking. They could also change the rules for parking in areas where it’s now unrestricted and free, or try a combination of these options.

Cities could experiment with what’s called a scaled VMT tax: a fee for an AV to enter a downtown zone based on the number of miles it’s already traveled that day. This option might discourage an increase in housing sprawl with AVs and reduce the number of people using AVs to get downtown. In addition, encouraging AVs to be powered by electricity rather than gasoline would reduce the environmental impact of any additional travel.

Much of the land devoted to parking lots in today’s cities could be converted to parks, housing or commercial spaces, and reducing curb parking could allow for wider bike lanes or sidewalks. To take advantage of changing parking demand, cities could build adaptable parking garages that can be converted to other uses if they’re no longer needed. Garages with flat floors and exterior ramps, rather than interior ramps, can more easily be converted to commercial uses or housing.

Cities would need to look for other sources of revenues to supplement the money lost from parking taxes, revenues and tickets. Some of these resources may be recovered through VMT and congestion fees, or by replacing underutilized parking structures with new denser uses.

While robotaxis are not here yet, preparing now for changes in downtown parking and infrastructure could help cities respond when privately owned AVs start to hit the streets.

Why do college textbooks cost so much? 7 questions answered


Editor’s note: The high price of college textbooks has long been a sore point for students. Even though the price reportedly went down by 26% since January 2017 – the first decrease in years – the overall trend in recent years has been a steady incline. Amie Freeman, a librarian at the University of South Carolina, explains the forces behind the prices.

1. How much are students spending on textbooks these days?

The National Association of College Stores reports that students spent an average of US$415 each on required course materials during the 2018-2019 school year. The College Board says students should budget $1,240 annually for books and supplies.

Several factors make course materials so expensive. First, there’s not much competition in the textbook industry. Just five publishers control about 80% of the textbook market, and two of those announced plans in May 2019 to merge by early 2020. Second, students have little choice in the materials they purchase since content is usually assigned by professors.

2. How do high prices affect students?

High textbook costs have negative effects on students. Many students report not purchasing required texts, taking fewer courses or even earning a poor grade as a result of not having a required text. For instance, a 2018 survey of students at public colleges and universities in Florida found that the high cost of textbooks had led 64.2% of students to not buy a required textbook and 42.8% to take fewer courses. Additionally, 35.6% said the high cost of textbooks caused them to earn a poor grade and 22.9% said it led them to drop a course.

The cost of textbooks can also lead students to rack up more student debt if they rely on financial aid to pay for course materials.

3. What are Open Educational Resources?

Colleges and universities have been active in promoting and developing affordable textbooks, including Open Educational Resources, more commonly known as OER. Open Educational Resources are educational materials – often in digital form – offered freely and openly for anyone to use.

The use of OER has saved students around the world over a billion dollars, and the vast majority of those savings have been reaped by students in the United States and Canada. Research has shown that students using OER do as well as or better than students using traditional course materials, with even better results for less financially secure students.

4. Is there any downside to Open Educational Resources?

Two of the most common complaints about OER are that there’s not a text available for every subject and that homework assignments and other accompanying materials for OER are not as well developed as commercial offerings. The good news is that both of those downsides are being addressed. Grants and funding allow for the steady creation of a larger base of customizable open textbooks and secondary resources.

Faculty members also express concern over the quality of OER. The quality of OER can vary, but many are written by experts and have faculty reviews available to assist instructors in selecting materials that suit their needs.

5. What else are schools doing to bring down costs?

Some college libraries loan textbooks or provide electronic resources to students for free. One of the biggest efforts going out right now is known as “inclusive access.” This is an arrangement where colleges provide students with discounted digital access to course content on the first day of class by billing the student.

Some colleges work with publishers or bookstores to offer students digital textbook subscriptions. Through these subscriptions, a student pays a subscription fee that gives them access to all the materials they may need from a particular publisher for a semester or a year. If a student is assigned several textbooks from this publisher, it may be worthwhile. However, it probably wouldn’t be a good deal if a student is assigned only one or two texts from this publisher.

6. Will physical textbooks ever become obsolete?

The digital versus print conversation is ongoing, but I think that there will always be learners who are better able to comprehend print over digital content. It’s clear that publishers are moving more toward digital offerings, but it’s unlikely that students will be able to print these materials or buy a print copy without additional costs. OER licenses, on the other hand, usually permit students to print as much content as they’d like, which is beneficial for students who don’t learn as well from digital texts.

7. What can students do to cut costs?

If a student’s assigned materials aren’t automatically charged to his or her tuition, the student could shop around both online and in-store to find the best rate. Some students search one of the many cost comparison sites, such as TextSurf, available online. A student might also consider a digital or physical rental if the student doesn’t plan to use the material after the course ends. If the college or university offers access to textbooks through the library, that’s a great place to save money. Most students who skip purchasing their course materials fear their grade will be negatively affected, so it’s essential that these cost-saving opportunities, alongside the option of open textbooks, are available to students.
