A Finnish study found that car collisions with moose and deer peak one hour after sunset, reaching crash rates 30-80 times higher than daylight hours. The risk is also present during dawn, with Finnish deer being descendants of white-tails imported from America in 1934.
Researchers at MIT have developed a new alternator design that significantly increases electrical power in future cars while also improving fuel efficiency. The technology, which uses active switches to control current flow, solves several technical problems associated with higher-voltage systems.
Researchers found unexpectedly high levels of ammonia in the exhaust of gasoline-powered cars on a southern California freeway ramp. The study suggests that cars are adding twice as much ammonia to the air as livestock do, with a small share of vehicles producing most of the pollution.
A new study by Valerie Hans reveals that potential jurors are skeptical of people who file whiplash lawsuits, leading to doubts about the legitimacy of claims. The research found that 92% of respondents believed frivolous lawsuits are common, resulting in lower settlements and more jury trials.
Teenage drivers face increased risks of fatal crashes when transporting more passengers, particularly those under 30 years old. Researchers recommend graduated licensing systems to mitigate this risk and reduce motor vehicle crashes among teenagers.
Engineers at Ohio State University have developed a method of computer analysis that extracts valuable information from the pitches of sound coming from a car, revealing insights into engine performance and driver technique. The same technique could be applied to other complicated machinery, such as power plant turbines.
A joint project between Nissan and MIT, the system uses computer and sensor data to monitor driving patterns and predict actions. With accuracy of 95%, it aims to build cars that adapt to individual drivers' needs.
Researchers found that Japanese students used an intuitive process to make decisions, while Americans relied on 'number-crunching' and careful information processing. The study suggests that cultural differences play a significant role in influencing how people make decisions, with implications for global business.
The new high-strength, ultra-thin steels are being tested for endurance on life-size testing rigs to simulate 40,000km of rocky road driving. The materials range in thickness from 0.7 to 2 mm and have improved fatigue properties.
Stroke patients in rural areas are being transported to comprehensive stroke medical centers via helicopters, where they can receive life-saving treatment and reduce disability. The study found that all five TPA-treated patients survived, with two having excellent outcomes and one major deficit.
A new technique discovered by Lars Sørensen allows thieves to unlock and steal from cars using handheld computers, exploiting vulnerable infrared remote controls. The method is being taken seriously by car manufacturers, who are investigating ways to mitigate the threat.
Researchers at Ohio State University have developed new radio antennas that can be embedded in car windshields, potentially reducing the need for air conditioning and making cars more energy-efficient. The designs use materials already present in car windows to create invisible antennas that receive AM and FM signals.
Researchers have developed a new 'self-strengthening' plastic that can be used to make car body panels. The process uses threads of polypropylene to create a rigid sheet with strength similar to composite materials.
A study by Professor Geoffrey Underwood found that police presence is the least anger-provoking and discourtesy is the greatest trigger for road rage. Drivers who experienced near accidents reported increased anger levels, particularly when they were not at fault.
A University of Toronto report suggests charging drivers for environmental damage caused by their cars can encourage sustainable transportation habits. The study found that combining increased prices with better urban planning led to the most significant changes in driving behavior and fuel emissions.
Carpooling expert Dorothy Singer offers practical advice on how to create a safe and enjoyable experience for children. Key tips include planning games, explaining rules, and prioritizing safety above all.
Researchers found that people demonstrate territorial behavior in parking lots, delaying departure times when another car wants the space, and becoming more aggressive with honking cars. This behavior is counterproductive, wasting time and effort.
A University of Illinois professor and his students have developed a power-tracking circuit that maximizes electrical power-conversion process efficiency. The circuit automatically adjusts to provide maximum energy out of solar cells for various applications, including large home appliances.
Researchers at Penn State have discovered that certain vegetable oil formulations can perform as well or better than commercial standards in tests for high-temperature resistance, slipperiness, and evaporation loss. This breakthrough has the potential to provide a more environmentally friendly alternative to traditional lubricants.
A European research project will develop high-tech sensors for cars to detect air pollution and enforce EU regulations. The sensors will be capable of detecting a range of gases, including CO, in real-time, allowing drivers to take action to reduce their impact on the environment.
