  • Why traffic accidents with cyclists are becoming increasingly more common
    on April 19, 2018 at 5:10 pm

    The bicycle is a cheap and ecological way of transport, and it is also a healthy option. This is why the number of cyclists in cities has increased in recent years, but so has the accident rate. A study confirms that these incidents are caused by a combination of inadequate infrastructures and risk behavior on the part of drivers and cyclists. […]

  • From property damage to lost production: How natural disasters impact economics
    on April 11, 2018 at 9:41 pm

    When a natural disaster strikes, major disaster databases tend to compile information about losses such as damages to property or cost of repairs, but other economic impacts after the disaster are often overlooked -- such as how a company's lost ability to produce products may affect the entire supply-chain within the affected region and in other regions. This may give an incomplete picture of the full financial impact of the disaster. […]

  • Fleet of automated electric taxis could deliver environmental and energy benefits
    on March 28, 2018 at 12:34 pm

    It may be only a matter of time before urban dwellers can hail a self-driving taxi, so researchers decided to analyze the cost, energy, and environmental implications of a fleet of self-driving electric vehicles operating in Manhattan. They found that shared automated electric vehicles, or SAEVs, could get the job done at a lower cost -- by an order of magnitude -- than present-day taxis while also reducing greenhouse gas emissions and energy consumption.
