Researchers found that programming autonomous vehicles in advance leads to more cooperative decisions, as people prioritize collective interests over short-term rewards. This effect generalizes beyond the domain of autonomous vehicles and has implications for shaping societal dilemmas.
Researchers at George Washington University found that decentralized systems perform better when individual parts are less capable, as overly smart components lead to overcorrections and mistakes. This discovery has potential applications in company structure, autonomous vehicles, AI algorithms, and even biological evolution.
Self-driving cars will slow traffic by cruising at low speeds to avoid high downtown parking fees. Cities face challenges regulating autonomous vehicles, which can create havoc if not properly managed. Congestion pricing is proposed as a solution to reduce congestion and pollution.
The study explores the potential impact of autonomous vehicles on urban tourism, highlighting both benefits such as reduced traffic congestion and improved foreign car hire processes, as well as concerns over job losses and increased urban sprawl. As AVs become mainstream, urban attractions may be transformed, and new industries like A...
A study by CNRS and researchers gathered 40 million moral dilemma responses from web users worldwide. The data revealed global moral preferences guiding decision makers, prioritizing human lives over animals, saving the largest number of lives, and protecting the youngest over older people.
A massive global survey on autonomous vehicle ethics found that people generally prefer sparing human lives over animal lives and young people's lives. However, regional variations were observed, particularly in the eastern cluster of countries where preference for younger people was less pronounced.
Researchers have developed a new material with high birefringence properties that can improve infrared detection in dense fog and dark conditions. This technology may enable faster deployment of autonomous vehicles and create more efficient heat sensing tools for firefighters.
A new lane-change algorithm developed by MIT allows autonomous vehicles to model an entire range of driving styles, from conservative to aggressive, with safety guarantees. The system computes buffer zones on the fly and ensures collision avoidance within a given time frame.
The AVENUE project, led by the University of Geneva, aims to develop and test autonomous vehicle services in European cities.

Researchers are developing a miniature collision detection sensor system that could drastically improve the safety of autonomous vehicles. The ULTRACEPT project combines near-range collision detection, long-range hazard perception, and thermal-based collision detection tools to overcome current limitations.
A new study found that autonomous vehicles can minimize environmental impacts with energy-efficient design and operational benefits outweighing increased energy use from sensors and computers. The study showed a 40% reduction in greenhouse gas emissions for electric powertrains versus internal-combustion engines.
A UMass Lowell professor is leading a research study on the ethical dilemmas posed by autonomous vehicles. The team aims to develop decision-making algorithms that balance individual rights with societal welfare. They will also investigate cybersecurity and privacy concerns related to self-driving cars.
New research shows that a small percentage of self-driving cars can significantly impact road flow, eliminating phantom traffic jams and reducing fuel consumption by up to 40%. The study demonstrates the potential for autonomous vehicles to regulate traffic flow and improve efficiency.
A new study suggests that autonomous vehicles could facilitate pedestrian-oriented urban neighborhoods, as pedestrians can act unpredictably and force self-driving cars to stop. However, the adoption of autonomous vehicles may be hampered by their strategic disadvantage in urban traffic.
Researchers at UC Riverside have developed a reliable and accurate navigation system that exploits environmental signals like cellular and Wi-Fi to support autonomous vehicle development. The technology can be used as an alternative or complement to GPS-based systems, enabling consistent and tamper-proof navigation.
A recent study by MIT researchers found that the public takes a utilitarian approach to autonomous vehicle safety, minimizing casualties in extreme situations but prioritizing personal safety. This 'social dilemma' may lead to conditions becoming less safe for everyone as individuals act in their own self-interest.
Researchers at Chalmers University of Technology are developing a self-driving truck that uses animal-inspired behavior to improve safety and adaptability. The truck's software, OpenDLV, is designed to react to unexpected situations by mimicking the way animals respond to their environment.
A novel technique called model predictive path integral control (MPPI) helps autonomous vehicles maintain stability at the edge of handling limits.
