SwRI is exploring using stereo cameras, or stereovision, as an alternative to lidar sensors in automated vehicles. SwRI's stereovision algorithms create disparity maps that estimate the depth of roadway features and obstacles. The left image shows how a conventional camera sees an off-road trail. The middle image shows a lidar image of the same trail. The right image shows a stereovision disparity map based on SwRI's algorithms, where colors indicate…

Multi-objective multigraph feature extraction for the shortest path cost prediction. Credit: Green Energy and Intelligent Transportation (2023). DOI: 10.1016/j.geits.2023.100129 As emerging urban air mobility concepts such as air taxis, on-demand aircraft, and large unmanned aerial vehicles become integrated into daily life, ensuring their smooth interaction with existing conventional airport infrastructures is imperative…

Volkswagen delivered some 9.2 million cars to customers in 2023. German auto giant Volkswagen on Wednesday reported a forecast-beating rise in profits for 2023, boosted by higher vehicle deliveries, but gave a cautious outlook for this year.…

Credit: CC0 Public Domain A small team of environmental scientists has found via simulations that rerouting commercial airplanes to reduce contrails would be less expensive than previously thought. In their study, published in the journal Environmental Research: Infrastructure and Sustainability, the group used data from prior studies to create simulations of airplanes routed to prevent the development of contrails.…

Researchers at Chalmers University of Technology, in Sweden, have developed a new truck front concept to significantly reduce fatal crashes in car-truck collisions. The new truck front comes after the EU regulations for the maximum length of a truck were lifted. Crash tests on the new truck front were carried out by the Swedish Transport Administration, Trafikverket, and show that better truck designs can reduce passenger car compartment deformations…

This innovative control method accounts for the wave loads present in real sea conditions that affect the maneuvering performance of autonomous ships, providing an optimized controller for time-efficient navigation. Credit: Daejeong Kim from Korea Maritime & Ocean University The study of ship maneuvering at sea has long been the central focus of the shipping industry. With the rapid advancements in remote control,…
