The number of middle-aged Australian men who cycle on weekends has doubled in recent years, but the rise of the so-called 'Mamils' (middle aged men in lyrca) is confined to men in more affluent suburbs, says research in today's Medical Journal of Australia.
According to the latest World Health Organization (WHO) report on road safety, more than 1.3 million people die on the world's roadways each year -- and millions more are injured or disabled.
Laws to ban or curb drivers' use of cell phones and other handheld devices have greatly reduced the rate of fatalities for motorcyclists, according to a new study from Florida Atlantic University and the University of Miami. Results show that states with moderate to strong bans have motorcycle fatality rates that differ by as much as 11 percent compared to states with no bans.
Hydrogen-powered vehicles emit only water vapor from their tailpipes, offering a cleaner alternative to fossil-fuel-based transportation. But for hydrogen cars to become mainstream, scientists need to develop more efficient hydrogen-storage systems. Now, researchers reporting in ACS' Chemistry of Materials have used metal-organic frameworks (MOFs) to set a new record for hydrogen storage capacity under normal operating conditions.
A new study from Northwestern University compared Evanston and Humboldt Park residents' attitudes toward various modes of transportation. The researchers found that Evanston residents more readily accepted new active mobility modes, such as bikeshare programs. But Humboldt Park residents exercised skepticism toward such programs, viewing them as signs of privilege and gentrification.
A contemporary city expands; it is stitched together with communications, but lacks integrity. Districts, urban communities and practices are so heterogeneous, that they often don't interact with each other. A united space is split into fragments. Communication is replaced with alienation. Dmitry Zamyatin, geographer and researcher of culture, chief research fellow at the Graduate School of Urbanism of the Higher School of Economics, called this phenomenon a 'post-city.'
In the first study to assess the energy impact of smart technology in cars, researchers at Stevens Institute of Technology have put a number on the potential fuel-cost savings alone: $6.2 billion.
Mining data to analyze tracking patterns, Civil Engineering Prof Sharon Di can infer the population travel demand level in a region from the trajectories of just a portion of travelers. She found three distinct groups whose demographics she could infer based on their travel patterns: seniors, who travel to a wider variety of places in a day; workers, who stay mostly at work or at home; parents, who visit more individual places in a day.
As much as 20 per cent of jet fuel burned in Norway in 2030 could be biofuel made from the country's forest residues. This alone could cut greenhouse gas emissions from Norway's aviation sector by 17 per cent.
Researchers found that small improvements to a city's ParkScore -- an evaluation of a city's park system -- could lead to more physical exercise for its residents. The Trust for Public Land created the ParkScore as an index to rank the park systems of the nation's largest 100 cities, they added.
