» We cannot bank our hopes for a less car-dependent future on the supposed preferences of a new generation.
The plateauing and decline in U.S. vehicle miles traveled per capita that occurred between mid-2005 and mid-2014 was described by some hopeful commentators as a dramatic shift that was indicative of the preferences of a new workforce. Yes, it coincided with the recession and an increase in gas prices, they said, but it was really more about generational change. Whereas in the past Americans dreamed of living in the suburbs and traveling virtually everywhere in their single-occupant automobiles, now Americans, addicted to their smart phones, are looking for walkable, urban living. Evidence suggests that they may have had a point: The age at which people registered for drivers licenses is increasing and certainly neighborhoods in central neighborhoods in city after city have been blossoming of late.
The more recent uptick in per-capita vehicle miles traveled

» 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

» Coupling real estate investment with the construction of new transit lines is the future, but the conditions need to be right.
Public development and ownership of the transportation system in the United States provided some broad, important social benefits that would not have been possible had our governments left it in the hands of the private sector. The downfall of the public transit and rail industries between the 1930s and 1970s throughout the country (itself partly a consequence of government investment in roads) was due to the fact that those services were no longer profitable. Government intervention through takeover of bankrupt lines kept those services operating and ensured the continuing existence of what is truly an essential public service in our major metropolitan areas.
Yet with the governments takeover of transit services, our regions lost a powerful skill that private transportation providers a century ago used well: Connecting new development with transit investments. The history of

» A new report attempts to quantify the relative merits of development near transit. What value can this tool bring for planners?
Transportation and land use are inextricably linked. Building a new rail line may expand development; new development may expand use of a rail line. The direct connection between the two makes differentiating between cause and effect difficult to measure. Transportation planners frequently make the argument that a new investment will produce new riders, for example, but whether those riders would have come anyway is not a simple question to answer. There is no counter-factual.
Nevertheless, planners have invested decades of considerable work in the pursuit of transit-oriented development (TOD), under the presumption that clustering new housing, offices, and retail will result in rising transit use and, in turn, reduce pollution, cut down on congestion, and improve quality of life. There remains some controversy about the effectiveness of TOD investments

» Streetcar projects promise new development along their rights-of-way. But cities must allow new transit-oriented buildings to be built nearby. A look at St. Louis and Portland.
In the United States, streetcars have assumed a dramatic new prominence, in part because of increasing federal support. In dozens of cities, new lines are under construction, funded, or in planning thanks to local political leadership that recognizes the benefits of such investments in relatively cheap new rail lines. While streetcars are typically not the most efficient mobility providers — compared to light rail lines and often even buses, they are slower and more likely to be caught in traffic — they are promoted as development tools. Streetcars, it is said, will bring new construction and the densification of districts that are served by the new rail lines.
But streetcars alone aren’t enough to spur construction of residential and commercial buildings in neighborhoods with
