» 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

» A review of twenty one metropolitan areas shows that most are seeing an increasing percentage of their population growth — or a decreasing percentage of their loss — in their core counties.
Last week, the U.S. Census Bureau released its annual population estimates for counties as of July 2011. These data provide significant insight into changing population trends in the United States, and the results offer considerable support for the argument that the country’s growth is moving back into its cities, at least to some degree.
National coverage of the data release focused on the fact that the data showed a significant drop in residents moving to exurban counties at the edge of metropolitan areas. The massive creation of housing at the far reaches of regions appears to have slowed to a trickle, and even the movement of the population from Northeastern and Midwest metropolitan areas to Southern and Western areas
