It turns out trying to expand the freedom of the open road has its limits—when taken too far, it can end up driving people apart.

New transit stations don’t have to mean gentrification or displacement
Major transit investments like new light rail lines or stations can transform neighborhoods and cities — in certain respects, that’s the point. The new infrastructure can make a city more vibrant and accessible to all, while encouraging the development of more walkable neighborhoods that make it easier to get around without a car, reduce emissions, and improve safety. But planners can take steps to ensure those benefits are shared among everyone, not just younger professionals or affluent newcomers.
Rural town centers can provide transportation benefits similar to those of urban areas
People living in dispersed rural areas face some of the greatest transportation challenges, according to a new study. However, living in more concentrated rural villages helps alleviate those challenges. Ensuring people can get around without relying on a car—even in rural pockets—is key to meeting their needs more affordably.
Mobility hubs can increase access for disadvantaged groups
For DOTs looking to create a more connected and multimodal transportation network, mobility hubs are an emerging piece of infrastructure that can make changing modes and traveling across a region more convenient and environmentally friendly. But not everyone has the same ability to access and use these hubs. State DOTs looking to build mobility hubs can incorporate the needs, ideas, and feedback of disadvantaged groups to better plan, design, and build these spaces for everyone who might use them.
Measuring Accessibility: Expanding the Practice
Wednesday, August 23, 2023
As agencies continue to integrate accessibility analysis into policy and planning, new research can guide the expansion of current and best practices. In this session we will talk with Louis Merlin from Florida Atlantic University and Dana Rowangould from the University of Vermont about their research into pedestrian and other accessibility metrics, and the practitioners who use them.
When driving gets tough, the tough adapt
Conventional thinking holds that congestion stifles the economy. Sitting in traffic or having it take longer to get someplace important would seem to be a drain on productivity. On the contrary, a group of Texas researchers looking at travel survey data from the Puget Sound area of Washington State found that travelers exposed to traffic congestion and travel delay will simply find a means of getting from point A to point B that doesn’t rely on driving. Their novel approach incorporates data on whether people choose to live in places that support their preferred travel options or way of life, addressing the question of residential self-selection.
Remote work could increase driving and transportation emissions
The impacts of telecommuting often come up in SSTI’s work around travel demand management and climate action plans, so our team makes a point of staying on top of the latest relevant research. Although the pandemic showed us that remote work helped cut traffic considerably, especially in major job centers, the verdict is still out on whether widespread telecommuting could really help lower travel demand. A growing number of studies suggest it could have the opposite effect.
Millennials aren’t driving as much as previous generations
The consumption choices and lifestyle preferences of Millennials—those born between 1981 and 1996—and their differences from those of the previous generations have repeatedly piqued academic and policy makers’ interests. Although some suggest they might just be slower in adopting previous trends, a recent study from the University of Texas at Austin suggests that they are a generation that prefers to drive about 8-9 percent less than Generation X and Baby Boomers, and that they might continue to drive less as they get older.
Findings from Toronto: Sticks and carrots for TNCs
We have a lot of evidence that venture capital-subsidized transportation network companies are cannibalizing transit and driving up VMT. Now a new study of this phenomenon examines the patterns of TNC trip making and suggests a system of taxes and subsidies in response. The paper, which employs data from a 2016 personal transportation survey, finds that TNC trips that could reasonably be taken on transit tend to occur during peak hours and for non-work trip purposes. Given policy concerns for maintaining transit ridership and reducing auto congestion and emissions, the authors suggest penalizing these TNC trips with higher fees.
Residential exposure to local traffic emissions associated with higher risk of stroke
A recent study finds that long-term residential exposure to locally emitted black carbon—primarily from traffic exhaust—is associated with higher stroke incidence. BC comprises a significant portion of particulate matter. Although BC is a known health hazard with health effects that are especially pronounced in populations in dense urban areas, the U.S. does not currently include it as a separate criteria pollutant in its National Ambient Air Quality Standards.
