Data generated by travel modes can inform planners and regulators in improving the transportation system, but private mobility companies often restrict their access for concerns about privacy and competition.
Among the factors that stand out in the "Spotlight on Highway Safety" report released Thursday by the Governors Highway Safety Association is increased "death by SUV," which kill at a higher rate than cars. Distraction, however, is hard to prove.
Colorado will join California and nine other states in requiring that a percentage of new light-duty vehicle sales are zero-emissions, thanks to the first executive order signed by Democratic Gov. Jared Polis on Jan. 17.
It's well known that an electric vehicle is only as clean, from a greenhouse gas perspective, as the electricity it consumes to power it. A new study finds that the electricity used in the manufacturing of car batteries also must be considered.
The Insurance Institute for Highway Safety released a study on May 8 that attributes the increased number of pedestrians killed in part to road design that allows for higher speeds, fewer intersections and pedestrian crossings and more SUVs.
The International Energy Agency found that China and India were responsible for 40 percent of the increased energy demand. The biggest decrease in carbon dioxide emissions came from the U.S., largely due to increased use of renewables.
At stake are greenhouse gas emission standards for 2022-25 model year passenger vehicles. Relaxing these standards would likely doom efforts to reduce these emissions 40 percent below 1990 levels by 2030 as required by 2016 state legislation.
Both are problems, but globally, sports utility vehicles sales are proliferating far faster than cars, be they electric or petrol-powered, posing a major challenge for governments committed to reducing greenhouse gas emissions.
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.
Gasoline consumption in the U.S. peaked in 2007, but began climbing in late 2014 with the decline in gas prices. Last year almost set a new record, but increases in gas prices, fuel efficiency and more EVs could reverse the direction—but when?
It costs less than $40,000 and gets over 200 miles to a charge. The Tesla Model 3? Yes, and also the Chevy Bolt, which goes to market first. A New York Times technology columnist writes that 'size matters' when it comes to innovation.
Honda announced that low gas prices contributed to low demand for the Civic Natural Gas, the only compressed natural gas (CNG)-powered car for sale, the Civic Hybrid, and their first plug-in hybrid-electric vehicle, the Accord.
A Hummer weighs 2.6 times more than a Prius C, so it must contribute that much more to road wear, right? Actually, that's wrong, not even close. To understand the main cause of road wear, one must look at heavy, not light trucks.
