A new study in the Journal of Planning Education and Research compares the 2017 VMT patterns of Millennials to the 2001 patterns of Generation X. Both groups were at a similar age at the time of the surveys. Previous commentary has proposed that Millennials’ driving patterns would approach those of the previous generation once they aged into child rearing and more fully recovered from the recession of 2008. This study concludes that Millennials are not as likely to drive, even as they reach these traditional milestones.
The implications of California’s SB 743 (2013), which is widely if somewhat imprecisely known as the “move away from level-of-service to vehicle-miles-traveled bill,” became clearer last week, as Caltrans issued guidance on which transportation projects will require evaluation for VMT effects.
Traffic forecasts and other projections are often presented as a single line on a graph or number in a chart. But we know—now more than ever—that these predictions are full of uncertainties. The Sacramento Council of Governments (SACOG), for a new study in JAPA, puts hard numbers to some of those uncertainties in order to plan better for them.
Driving mileage in the United States climbed by just under 0.9 percent in 2019. On a per capita basis, the increase was just under 0.6 percent. The VMT figures come from FHWA’s latest Travel Volume Trends release.
There have been a number of studies studying the relationship between in-store and online shopping behavior and its impact on retail-related travel. A broadly accepted idea is that online shopping, in more ways than one, is substituting for in-store shopping and can thereby reduce shopping related travel. However, major demographic and economic factors affect shopping behavior, and expedited delivery options may reduce the potential of e-commerce to reduce VMT and greenhouse gas emissions.
The U.S. transportation field has tried many things to reduce traffic crashes, fatalities, and injuries: drunk-driving and seatbelt laws; in-vehicle safety improvements; wide, straight roads with crash zones; graduated licensing; and more. Yet traffic crashes still kill 35,000-40,000 Americans each year and injure millions. A new online resource that helps explain the situation. Fatalities are largely a function of miles driven, so you can’t be serious about Vision Zero without also being serious about VMT management.
For the longest time we’ve relied on the Highway Performance Monitoring System for understanding travel patterns and estimating vehicle miles of travel. But these estimates often have not been very accurate because of inadequacies in data collection. Big data is providing more precise and more complete information that can be used for both planning and seeing the impacts of policy. In a new report, StreetLight Data, a leader in the transportation big data field, is showing us how it’s done.
As transportation planners and environmental researchers look at climate policies, a smooth and equitable transition to a low-carbon global economy is an essential component. In the passenger vehicle sector, how will this process be affected by oil demand and EV adoption trends? A new report examines a number of EV penetration forecasts and summarizes the 2019 trends and their changes since 2018. The report focuses on passenger vehicles, which account for about 23 percent of oil demand. While other segments of the transportation sector—trucks, and aviation and shipping—account for about 29 percent of the oil demand, electrifying cars may be easier, according to the author.
A new survey of planning officials in California finds that most are embracing the shift from highway level of service to vehicle miles traveled for evaluating the environmental impacts of new development projects. While some are ditching LOS altogether, however, many still rely on it to measure traffic impacts.
In many ways, we can only speculate about a future with autonomous vehicles on the road. The effects on vehicle miles traveled are expected to be very different if AVs are privately owned versus shared. A recent post on Jalopnick reviews a study published in 2018, that focuses on the question of individual ownership. The results point to a potential worst-case-scenario; a catastrophic increase in VMT that could occur with the introduction of privately-owned AVs.
