Revolutionizing the Traffic Light21AVEP01_051/27/2025
Two start-ups are using cameras, sensors and AI to enable more efficient vehicle flow through intersections. Every motorist has experienced the frustration of waiting at a red light when there is no traffic in sight. These days, countless household devices use sensors, cameras and connectivity to understand and respond to the world - so why do most traffic lights languish in the analog age, causing our vehicles to unnecessarily stop and idle? In a spring 2019 report, Guidehouse Insights forecast that just 7% of North America's signalized intersections would use so-called adaptive traffic-control technology in 2020. On a global level, that number was 2.3%.

The current state of the art methods can pose environmental challenges and be difficult to make economical at the industrial scale.
Pilot Flight Simulator Performance Under Distraction and Vibrotactile Situation AwarenessF-0080-2024-13435/7/2024
Maintenance of spatial orientation (SO) is achieved primarily through visual information where the horizon and celestial reference cues or flight instruments are used by pilots to infer aircraft orientation. However, cross checking the instruments in degraded visual environments can be complicated by factors such as workload, distraction, and situations where the vestibular and proprioceptive systems may provide false and competing orientation information. We describe experiments measuring pilot performance using a flight simulator under challenging conditions where the sensory information was controlled. Reducing available visual instruments increased the task difficulty. A wearable vibrotactile array could provide concurrent, additional orientation information. Increasing the flying task segment difficulty increased the perceived workload and also corresponded to an increase in accidents. Adding tactile orientation information reduced the accident rate.

The Advancement of Aerial Firefighting Concept of OperationsF-0080-2024-11605/7/2024
Advancing technology has driven continuous improvements across most aspects of human endeavors. In the time since the first modern helicopter flew in 1939, the world has seen inventions like the microwave, personal computers, cell phones, and the internet. If helicopters predate these society-changing innovations, then it stands to reason that the manner in which helicopters operate has drastically shifted as well. Specifically, this paper reviews historical concepts of operations (CONOPS) in rotorcraft aerial firefighting and analyzes where technology advancements have made an impact on firefighting operations and the performance of helicopters in suppressing fires. These shifts were evaluated using analytical assessments and highlighting snapshots in time of how capability impacted the aerial firefighting mission effectiveness. As companies innovate and technology advances, further benefits to rotorcraft CONOPS in aerial firefighting will be realized.

The Short-flight Alternative22AVEP04_084/1/2022
The Budget Airline Car is an EV alt-shuttle seating six adults, with luggage storage in each door. Short-haul airline flights can be a great convenience for travelers, but they produce more CO2 emissions - about 250 g/km per person - than any other form of passenger transportation, including compact EVs and electric trains. That's about 25% more emissions than long-haul flights, because short-hop flying uses proportionately more fuel at takeoff and landing. Could an automotive alternative offer a solution? That is what Car Design Research (CDR), a U.K.-based consultancy, set out to investigate, working with design associates Yichen Shu in China and Aditya Jangid in India. The resulting concept is the Budget Airline Car, one of six new passenger-vehicle types that CDR director Sam Livingston and his team feel would be enabled by new mobility technologies.

Effects of combined Phone use and Alcohol-impaired Driving Behaviours among Female Drivers; A Driving Simulator Study2022-01-09723/29/2022
Driver behavior and passenger safety remain one of the foremost axes developed for investigative research in driving simulator studies. However, a plethora of studies on driver’s behaviour using driving simulators has seen the underrepresentation of female participants whose characteristics have scarcely been investigated. More tellingly, the responsibility of female drivers for road traffic accidents with respect to cell phone use and alcohol-impaired behaviours is overlooked. Using a driving simulator experiment, this study thematically modelled and analysed the combined upshot of cell phone use and alcohol-impaired tasks among 15 female driver participants. The experiment was carried out in an urban simulated environment to extract discrete responses from these intoxicated drivers at four different levels of blood alcohol concentration (BAC) (0%, 0.02%, 0.05%, and 0.08%). Vehicle telematic variables such as acceleration (m/s2), vehicle speed (m/s), angular velocity (rad/s2) and RPM

Direct Alert to In-Vehicle Infotainment (DAIVI)2022-01-02623/29/2022
Nowadays, the mobile phone features are widely used by drivers to get the notifications and alerts on the head unit. However, there are no available products in the market to get important notifications in Head units without the use of mobile phones. There are many important notifications that are critical for a user when he is away from home. Some of them are alerts from home security systems, smoke and gas detection alarms etc. Most of the existing systems push alerts to customer mobile phones. In this paper, the authors propose a concept to direct the alerts to In-Vehicle Infotainment systems. Proposed here is a new approach, Direct Alert to In-Vehicle Infotainment (DAIVI), in which the infotainment head unit will be able to get the notification or alerts without using a mobile phone. The DAIVI complements the existing systems of alerts to the user by using in-vehicle infotainment for alerting on the critical issue.

Bayesian Optimization of Active Materials for Lithium-Ion Batteries2021-01-07654/6/2021
The design of better active materials for lithium-ion batteries (LIBs) is crucial to satisfy the increasing demand of high performance batteries for portable electronics and electric vehicles. Currently, the development of new active materials is driven by physical experimentation and the designer’s intuition and expertise. During the development process, the designer interprets the experimental data to decide the next composition of the active material to be tested. After several trial-and-error iterations of data analysis and testing, promising active materials are discovered but after long development times (months or even years) and the evaluation of a large number of experiments. Bayesian global optimization (BGO) is an appealing alternative for the design of active materials for LIBs. BGO is a gradient-free optimization methodology to solve design problems that involve expensive black-box functions. An example of a black-box function is the prediction of the cycle life of LIBs
