AAA Study: Auto Ownership More Cost-Effective Than Ride-Hailing
Even after factoring in insurance, parking, depreciation, fuel, repair, maintenance and licensing, urban dwellers would pay half the costs to travel, on average, nearly 11,000 miles annually in their own new car rather than relying on ride-hailing.
Peak Motorization: Measuring Rates of Auto Ownership and Distances Driven
Passenger vehicle ownership and vehicle miles traveled per person and per household remain below their historic peaks set in 2006 and 2004, respectively, but they have been on the upswing for the past four to five years, according to new data.
Fuel Efficiency Just Became Much More Important
Two widely cited University of Michigan transportation researchers urge consumers to drive more fuel efficient vehicles to reduce their own carbon emissions as President Trump works to relax vehicle fuel economy standards.
Are EPA's Fuel Efficiency Standards the Next Environmental Rollback?
Next on President Trump's environmental chopping block may be a rollback of fuel efficiency standards. Two auto associations have asked EPA Administer Scott Pruitt to review a decision made last month to retain a 54.5 mpg target.
EPA Rejects Automakers' Bid to Reduce Fuel Economy Standards in Midterm Review
The U.S. Environmental Protection Agency ruled that existing technology allows for increased efficiency in model years 2022 to 2025. The 2011 rule to achieve 54.5 mpg by 2025 required a 'midterm evaluation' to see if the final target was achievable.
2016: Year of the Sports Utility Vehicle
Last year set two notable vehicle records. First, the most cars ever sold, at 17.54 million. Second, light trucks accounted for almost 61 percent of all sales. Sales of more fuel efficient car fell, though electric vehicle sales increased.
Americans Shifting Away From the Auto, Maybe
The auto may no longer be "the quintessential symbol of American mobility, status and independence," opines Robert J. Samuelson for The Washington Post, as the latest demographic and auto ownership data point to a change in American mobility.
Hybrid and Electric Cars Take a Downturn in the Used Car Market
It's not just Americans favor SUVs and light truck over compact cars, but that a majority of EV and hybrid owners who have traded in their cars are opting for all-gas vehicles, and that spells trouble for meeting President Obama's climate goals.
California Road Charge Pilot Launches July 1; Gas Tax Increase Still Needed
Two notable transportation developments occur in California on July 1. First, a pilot road charge program begins—5,000 motorists will be charged by the mile driven. Second, the gas tax drops by 2.2 cents. An analysis by ITEP looks at both.
U.S. Gasoline Consumption Up, Oil Production Down
Gas prices are on the rise, though they will remain well below 2014 levels through this year. U.S. oil production dropped by 600,000 barrels from last year, while gas consumption is on track to break the 2007 record thanks to cheap gas and more SUVs.
Demographic Changes Spell Trouble Ahead for Auto Industry
It's not only young adults who are delaying in getting drivers licenses, but a drop in licenses among all age groups according to a new analysis of license data from 1983-2014 by the University of Michigan Transportation Research Institute.
Vehicle Miles Traveled Hits Record; Fuel Efficiency Decreasing Too
New figures from the Federal Highway Administration show no abatement in increasing vehicle miles traveled (VMT). While low oil prices have been beneficial for the environment on the production end, it is wreaking havoc on the consumption side.
If Congestion Is Getting Worse, Why Are We Spending Less Time Traveling?
The University of Michigan Transportation Research Institute released its eighth report on peak motorization in the U.S., an evaluation of time spent traveling for a broad category of purposes, not just work. From 2004 to 2014, total time decreased.
Bay Area Leads the Nation in Reducing Solo Commuters
According to the Census Bureau's American Community Survey on commuting to work, one subregion in the Bay Area can claim accolades for having achieved the largest drop in solo-commuting from 2006, scoring the third lowest drive-alone rate in 2013.
Do Driverless Car Safety Features Merit Fuel Efficiency Credit?
Manufacturers say yes, arguing that the reduction in vehicle crashes decreases traffic congestion. Other features improve traffic flow. But these are safety technologies, not emission-reducing measures, that critics worry will water-down CAFE.
Cheap Gas Defeats Fuel Efficiency Goals
The effect of low gas prices on motor vehicle selection by consumers could set back President Barack Obama's climate legacy, which includes obtaining fuel economy standards of 54.5 mpg by 2025.
Like the Old Days: Average Fuel Economy Declines in the United States
A recent study at the University of Michigan Transportation Research Institute showed that September saw the largest decline in average fuel economy, from 25.8 mpg to 25.3 mpg, since December 2011.
The "College-Dense and Car-Light" Theory
Is there a relationship between carless households and density of college graduates? Derek Thompson of The Atlantic connected the dots using Michael Sivak's latest 'peak car' study and saw a relationship between the two variables.
Welcome to the Age of "Driving Light"
As a nation, we are driving less, but we are increasingly stuck in traffic. What explains this paradox? Using Portland as an example, where driving peaked in 2004, Joseph Rose attempts to explain with lots of help from transportation experts.
Have You Noticed Fewer Cars on the Road Lately?
While the decline may not be visible, total auto ownership peaked in 2008 according to a new report by Michael Sivak of the University of Michigan's Transportation Research Institute. He set out to determine the cause - was it the economic recession?
