» Do we have the political will to build a different type of transportation system? Or will the rise of autonomous vehicles simply reinforce existing norms?
There is now no debate over whether automated technology will revolutionize the transportation system—the question is just when it will do so. Industry watchers who four years ago predicted it would take a decade and a half to realize fully driverless cars now suggest they’ll be online, everywhere, by 2020.
Indeed, just this week, Tesla announced that all of the vehicles it is producing, including its newest, cheapest Model 3, will have “full self-driving capability at a safety level substantially greater than that of a human driver.” Its cars will feature eight cameras and 12 ultrasonic sensors, designed to evaluate the world around the cars and respond immediately. The technology won’t be activated immediately; it will collect data as drivers use the cars to improve its

» Self-driving cars could alter how we get around—and also change the way our cities work.
Even the concept of a self-driving car is enough to get people talking in raptures about the potential for a utopian future society. It could fulfill the promise of “personal rapid transit” transportation planners hoped to provide decades ago, offering personalized point-to-point service without the hassle, congestion, or crashes involved with driving.
The autonomous vehicle, some predict, will replace many of today’s forms of transportation and radically expand mobility by allowing people, including the young, old, and disabled, to get around without having to walk, without having to know how to drive, and without having to wait for a bus or train. Operating without a driver and using electricity for power, the autonomous vehicle could be cheap to operate and environmentally friendly. It could, in fact, replace car ownership for many households.
We’re years away from the

» A major roadway is advanced, in violation of the consensus-based plan.
Yesterday, the Chicago Metropolitan Agency for Planning (CMAP) Metropolitan Planning Organization (MPO) policy committee voted to approve the addition of a major new highway to the regional plan document. If built, the Illiana Expressway will run 47 miles between I-55 and I-65 in Illinois and Indiana, about 10 miles south of the existing built-up area of the Chicago region.
The project was supported by the relevant state departments of transportation as an essential complement to the existing mobility system and an economic development tool. But the decision to add it to the regional plan suggests a breakdown in what had been until recently a metropolitan-wide consensus about which projects to fund. Though the adoption of the project does not mean the end of the plan, it does imply that sticking to a regional plan in the face of political

» Even as Dallas finishes work on a new light rail line, plans for a new highway along a parallel corridor advance.
This summer, Dallas’ Orange Line will be extended five stations northwest of downtown. The light rail service will expand what is already the United States’ longest such network and improve connections between central Dallas, the suburb of Irving, and — in 2014 — Dallas-Fort Worth International Airport. Yet billions of dollars in new construction have barely increased transit use; just 4.2% of the city’s commuters use public transportation to get to work, according to the U.S. Census Bureau. If there is one city that proves that simply building transit does not attract people to transit, this is it.
Investments in Dallas’ road infrastructure might provide some explanation for the situation. An astonishing seven grade-separated highways extend radially out from the city center in all directions.* This is a

» An all-electric, point-to-point system could revolutionize how we think about the automobile and significantly reduce the need for private cars in our cities.
American urbanites have already become quite familiar with the concept of car sharing through the rapid expansion of companies like ZipCar and I-Go; the ability to rent a car at a reasonable price at any time from a location within walking distance of home or work has dramatically reduced the need for at least some people to own private vehicles, since it covers the gap in service not provided by transit: Trips that are out-of-the-way, that require moving heavy goods, or that occur at inconvenient times. This is great for cities and for people, since not only does it reduce the need for parking, but it reduces vehicle capital expenses for everyone, since the cost of purchasing the car is effectively shared among many
