    on May 22, 2018 at 3:48 pm

    Researchers will present a new lane-change algorithm that splits the difference. It allows for more aggressive lane changes than the simple models do but relies only on immediate information about other vehicles' directions and velocities to make decisions. […]

  • Virtual-reality testing ground for drones
    on May 17, 2018 at 6:25 pm

    Engineers have developed a new virtual-reality training system for drones that enables a vehicle to 'see' a rich, virtual environment while flying in an empty physical space. The system, which the team has dubbed 'Flight Goggles,' could significantly reduce the number of crashes that drones experience in actual training sessions. It can also serve as a virtual testbed for any number of environments and conditions in which researchers might want to train fast-flying drones. […]

    on May 15, 2018 at 10:09 pm

    VTT's robot car, Marilyn, sees better than humans in foggy, and even snowy, conditions, and can now navigate without stopping -- including in bad weather. It can also see a human through fog and avoid accident automatically. […]

  • European cities soon to be ready for autonomous vehicles
    on May 14, 2018 at 1:55 pm

    Autonomous vehicles promise to be the next revolution in public transport. They should find their first users in suburban areas, which are less well served by traditional transportation networks. A new project will identify the needs and motivations of their future users, meet many of the technological and regulatory challenges, and design new business models, allowing these new services to develop. […]

  • Self-driving cars for country roads
    on May 7, 2018 at 11:42 am

    Uber's recent self-driving car fatality underscores the fact that the technology is still not ready for widespread adoption. One reason is that there aren't many places where self-driving cars can actually drive. Companies like Google only test their fleets in major cities where they've spent countless hours meticulously labeling the exact 3D positions of lanes, curbs, off-ramps and stop signs. […]

  • Should ethics or human intuition drive the moral judgments of driverless cars?
    on May 3, 2018 at 6:26 pm

    Driverless cars will encounter situations requiring moral assessment -- and new research suggests that people may not be happy with the decisions their cars make. Experiments designed to test people's reactions to a driving dilemma that endangers human life, revealed a high willingness for self-sacrifice, a consideration of the age of potential victims and swerving onto the sidewalk to save more lives -- intuitions that are sometimes at odds with ethically acceptable behavior or political guidelines. […]

  • Personal care products contribute to a pollution 'rush hour'
    on April 30, 2018 at 5:18 pm

    When people are out and about, they leave plumes of chemicals behind them -- from both car tailpipes and the products they put on their skin and hair. In fact, emissions of siloxane, a common ingredient in shampoos, lotions, and deodorants, are comparable in magnitude to the emissions of major components of vehicle exhaust, such as benzene, from rush-hour traffic. […]

  • Beltway to divert diesel trucks in Sao Paulo improved public health
    on April 27, 2018 at 12:52 pm

    A new study revealed that a beltway constructed to divert heavy-duty diesel vehicles traffic in the Brazilian city of Sao Paulo has reduced public health damage associated with exposure to diesel. The positive health outcomes of the intervention could guide the formulation of similar transport polices in other cities, where humans and diesel vehicles reside and transit in close proximity. […]

  • Safety of rear-facing car seats in rear impact car crashes
    on April 3, 2018 at 12:50 pm

    Experts know that rear-facing car seats protect infants and toddlers in front and side impact crashes, but they are rarely discussed when it comes to rear-impact collisions. Because rear-impact crashes account for more than 25 percent of all accidents, researchers conducted a new study to explore the effectiveness of rear-facing car seats in this scenario. […]

  • How self-driving cars could shrink parking lots
    on March 28, 2018 at 10:24 pm

    New research shows that adoption of self-driving cars -- also known as autonomous vehicles (AVs) -- could significantly reduce the amount of valuable urban space dedicated to parking. […]

  • Age and gender matter behind the wheel -- but not how you might expect
    on February 22, 2018 at 7:43 pm

    A new study explored the relationship between new drivers' skills and age, gender, organized sports and video gaming. The results suggest that mandatory training should be required for all novice drivers, not just teenagers. […]

  • Artificial intelligence and supercomputers to help alleviate urban traffic problems
    on December 11, 2017 at 7:59 pm

    Researchers have developed a tool that uses artificial intelligence to recognize objects in raw traffic camera footage and characterize how those objects move and interact. This information can then be analyzed and queried by traffic engineers and officials to improve the safety and performance of the city's transportation network. […]

  • Hearing hybrid and electric vehicles while quieting noise pollution
    on December 5, 2017 at 2:15 pm

    Low-emission vehicles are considered too quiet for hearing-impaired pedestrians, so the European Union is mandating that they be equipped with acoustic vehicle alerting systems. With these alert systems would come a marked increase in the amount of noise on the roads across Europe. […]

    on November 29, 2017 at 9:17 pm

    When researchers set out to study the environmental benefits of different modes of public transit in LA, they found some unexpected results: certain SoCal public transit routes that were entirely underground exposed passengers to greater concentrations of carcinogens in the air. […]

  • Leave a buffer for your bumper: Study contradicts practice of traffic light tailgating
    on November 27, 2017 at 8:20 pm

    The practice of packing tightly at traffic lights is widely accepted. Thanks to new research, drivers now have a good reason to dismiss this faulty line of roadway intuition. […]

  • A revolutionary invention detects black ice in traffic
    on November 27, 2017 at 2:31 pm

    A new invention revolutionizes the way black ice is detected and provides several other improvements in traffic safety as well. The software installed in vehicles can also guide drivers to drive more economically. Software-based, the invention can be installed into a majority of heavy vehicles in particular with no additional equipment. The new invention allows slippery road conditions to be detected accurately. […]
