The focus in this series is on vehicles per person, as opposed to total number of vehicles (which depends, in part, on the continuously increasing size of the U.S. The calculations used the total numbers of light-duty vehicles (cars and light trucks) from the Federal Highway Administration and the resident populations from ProQuest.
In this analysis, I compare the age composition of buyers of new light-duty vehicles (cars and light trucks) in 2007 and 2017. The main findings are as follows: Middle-aged persons purchased proportionally fewer vehicles in 2017 than in 2007 (down from 29% to 14% for those 35 to 44, and from 24% to 20% for those 45 to 54).
Michael Sivak at the University of Michigan Transportation Research Institute together suggest that the US now has—per person, per driver, and per household—fewer light-duty vehicles and that they are driven less than a decade ago. In the newer study, “ Has Motorization In The U.S.
The focus here is on distance driven per person and per household, as opposed to the absolute distance driven (which depends, in part, on the continuously increasing size of the U.S. Distances driven by all light-duty vehicles (passenger cars and light trucks) were obtained from the Federal Highway Administration. population).
Currently, the energy intensity (BTU per person mile) of driving is 57% greater than that of flying, according to a new analysis by Dr. Michael Sivak, Director, Sustainable Worldwide Transportation at the University of Michigan Transportation Research Institute (UMTRI). persons to at least 2.3 persons to at least 2.3
The vehicle proposes an application of the emissions-free light-duty truck to make essential garbage collection services more efficient and environmentally conscious.

In both instances, the distances to be compared are person miles. The derivation of person miles traveled by air is straightforward from the available monthly data: In 2021, the airline revenue passenger miles for domestic operations totaled 572 billion miles. persons ), we end up with 4,800 billion person miles.
The bottom line, he concludes in this third report, is that “ We drive fewer light-duty vehicles, we drive each of them less, and we consume less fuel.”. Fuel consumed per person. In 1984, the average amount of fuel consumed per person was 400 gallons. Fuel consumed per registered light-duty vehicle. Peak year(s).
Vehicle distance traveled per person in Great Britain is currently about one-half of the distance in the United States. I documented recent changes in distance traveled per person for cars and light trucks in the United States in a study published last month.). by Michael Sivak, Sivak Applied Research. Because British and U.S.
It turns out that, in the United States, the occupants of light-duty vehicles (cars, SUVs, pickups, and vans) annually contribute, on average, 7,958 pounds of carbon dioxide equivalent. Furthermore, indirect emissions, such as those from refining and transport of the fuel, were included by adding 24% of the direct emissions.
At the same time, total miles traveled per year by cars, sport utility vehicles (SUVs) and light trucks will increase about 60%, reaching about 14 trillion in 2040. As personal mobility increases, average new-car fuel economy (including SUVs and light trucks) will improve as well, rising from about 30 miles per gallon (7.83
Remote sensing a category broad enough to include both personal medical monitors and space weather forecasting is poised for a quantum upgrade, much like computing and cryptography before it. A new type of quantum sensor that promises both higher sensitivity and greater security has been proposed and tested in proof-of-concept form.
Supernova explosions, the catastrophic self-destruction of certain types of worn-out stars, are intimately tied to life on Earth because they are the birthplaces of heavy elements across the universe. At the time, about a decade ago, I was helping to refine a system for fabricating chips using extreme ultraviolet (EUV) light.
persons), the occupant distance travelled increased by 84% (from 3.182 to 5.867 trillion km). Sivak found that while the vehicle fuel economy of the entire light-duty fleet improved by 40% (from 13 mpg US to 21.6 occupants carried) decreased by 27% (from 1.9 mpg US, or from 18.1 l/100km to 10.9 mpg US to 29.8 mpg US, or 9.5
A study by a team at MIT has concluded that roughly 90% of the personal vehicles on the road in the US could be replaced by an electric vehicle available on the market today, even if the cars can only charge overnight. Together, the two datasets encompass millions of trips made by drivers all around the country.

The details of that specific situation may result in an electric vehicle parc somewhat different than in Western countries, other speakers noted, and may indeed—given the obvious scale of the China market—herald a major transformation in transportation, including the type and role of personal vehicles, others suggested.
Columbia University’s Center on Global Energy Policy and the University of California, Davis Institute of Transportation Studies analyzed four scenarios to understand how COVID-19 and other political, economic, social and technological drivers may impact transportation activity and global oil demand.
First, the measure used in this analysis for driving—vehicle miles traveled—includes travel not only by personal vehicles (cars, light trucks, and motorcycles), but also by medium and heavy trucks and buses. Two caveats are in order.
A new study by Michael Sivak, research professor at the University of Michigan Transportation Research Institute (UMTRI), found that in 2011, the peak probability of buying a new vehicle per driver in the US was among those between 55 and 64 years of age—a shift from four years earlier, when that peaked with the 35-to-44-year-old age group.
However, he notes, the rates of vehicles per person, licensed driver, and household reached their maxima prior to the onset of the current economic downturn. The focus of this research was on light-duty vehicles (cars, pickup trucks, SUVs, and vans). The number of light-duty vehicles in 1984 stood at 156.8 vehicles per person.
This project brings to life a connected car that essentially predicts the behavior of its driver, analyzes current and future driving conditions and creates a safer and hopefully less stressful experience for the person behind the wheel.
