Enhancing Pedestrian-Autonomous Vehicle Safety In Low Visibility Scenarios: A Comprehensive Simulation Method, Zizheng Yan, Yang Liu, Hong Yang Apr 2023

Enhancing Pedestrian-Autonomous Vehicle Safety In Low Visibility Scenarios: A Comprehensive Simulation Method, Zizheng Yan, Yang Liu, Hong Yang

Modeling, Simulation and Visualization Student Capstone Conference

Self-driving cars raise safety concerns, particularly regarding pedestrian interactions. Current research lacks a systematic understanding of these interactions in diverse scenarios. Autonomous Vehicle (AV) performance can vary due to perception accuracy, algorithm reliability, and environmental dynamics. This study examines AV-pedestrian safety issues, focusing on low visibility conditions, using a co-simulation framework combining virtual reality and an autonomous driving simulator. 40 experiments were conducted, extracting surrogate safety measures (SSMs) from AV and pedestrian trajectories. The results indicate that low visibility can impair AV performance, increasing conflict risks for pedestrians. AV algorithms may require further enhancements and validations for consistent safety performance …


Development Of A Safety Performance Decision-Making Tool For Flight Training Organizations, Marisa D. Aguiar Phd, Carolina L. Anderson Phd Jan 2023

Development Of A Safety Performance Decision-Making Tool For Flight Training Organizations, Marisa D. Aguiar Phd, Carolina L. Anderson Phd

National Training Aircraft Symposium (NTAS)

The purpose of the research was to create and validate a safety performance decision-making tool to transform a reactive safety model into a predictive, decision-making tool, specific to large, collegiate Title 14 of the Code of Federal Regulations (CFR) Part 141 flight training organizations, to increase safety and aid in operational decision-making. Using Monte Carlo simulation, the study conducted simulation runs based on true operational ranges to simulate the operating conditions possible within large, collegiate CFR Part 141 flight training organizations with varying levels of controllable resources in terms of personnel (Aviation Maintenance Technicians and Instructor Pilots) and expenditures (active …

Audit Of Road Safety Elements In National Road N25.2 “Prishtinë – Gjilan”, Gresa Xhemaili, Nol Dedaj Oct 2021

Audit Of Road Safety Elements In National Road N25.2 “Prishtinë – Gjilan”, Gresa Xhemaili, Nol Dedaj

UBT International Conference

With the increase of the number of vehicles and the number of kilometers of the road as well as the time of their construction, the number of accidents has also increased, therefore it is very important to audit the road elements (level of roughness, macro and micro deformations, turns, longitudinal and transverse slope, shoulders, erosion and filling in roads, drainage, etc.) which directly affect the safety of road traffic. The audit of road elements will give us a clear picture on the identification of road factor elements in certain road segments of the road N -25.2 Prishtina - Gjilan, which …


An Alternative Method Of Identification Of A Failed Engine In Twin-Engine Propeller Aircraft, Andrey Babin, Andrew R. Dattel Ph.D. Aug 2018

An Alternative Method Of Identification Of A Failed Engine In Twin-Engine Propeller Aircraft, Andrey Babin, Andrew R. Dattel Ph.D.

National Training Aircraft Symposium (NTAS)

Previous research revealed that wrong identification of a failed engine during flight is not an uncommon event in twin-engine propeller aircraft. Most accidents of this type have happened on takeoff when pilot workload was at its highest level. This study was based on the assumption that the “dead leg – dead engine” method was not efficient enough. An alternative method of identification of a failed engine, which involved a visual indicator inside a cockpit, was introduced and tested. Method: Student pilots from Embry-Riddle Aeronautical University who had not obtained multi-engine (MEL) rating were sampled and assigned to two groups – …


Uas Maintenance: A Critical Component In Maintaining Airworthiness, Bettina M. Mrusek Ph.D., Patti J. Clark Ph.D., Kristy W. Kiernan Ph.D. Aug 2018

Uas Maintenance: A Critical Component In Maintaining Airworthiness, Bettina M. Mrusek Ph.D., Patti J. Clark Ph.D., Kristy W. Kiernan Ph.D.

National Training Aircraft Symposium (NTAS)

Over the last several decades, the notion of traditional aircraft design has significantly changed. While there are many modern aircraft that resemble earlier models, their components, systems, and overall architecture have evolved, including the introduction of small unmanned aircraft systems. Despite the growing consumer attraction to own and operate these aircraft, the subsequent impact on safety is an area of intense concern. The requirement of an established maintenance program for manned aircraft is rooted in ensuring that all aircraft are deemed safe for flight. Preventive maintenance schedules are based on component reliability data, which minimizes unnecessary maintenance while preventing maintenance-related …


Uas Pilots Code: Tools To Advance Uas Safety & Professionalism, Ryan J. Wallace Ed.D., John M. Robbins Ph.D. Aug 2018

Uas Pilots Code: Tools To Advance Uas Safety & Professionalism, Ryan J. Wallace Ed.D., John M. Robbins Ph.D.

National Training Aircraft Symposium (NTAS)

As unmanned aircraft operations become more ubiquitous in the National Airspace System, one of the key remaining challenges is instilling the precepts of safety culture, aviation professionalism, airmanship, and effective aeronautical decision-making among these non-traditional aviators. To address these challenges, researchers codified best practices and operational recommendations from across the UAS industry, collectively publishing them in a compendium titled the UAS Pilots Code (UASPC). Guidance for the UASPC was informed by material assembled from leading governmental and industry organizations including: FAA, AEA, AMA, AOPA, ASTM, AUVSI, CANSO, EAA, EASA, EUROCAE, ICAO, ISO, JARUS, NBAA, RTCA, SAE, UVS, and others. Extensive …


An Alternative Method Of Identification Of A Failed Engine In Twin-Engine Turboprop Aircraft, Andrey Babin, Andrew R. Dattel Ph.D. Aug 2017

An Alternative Method Of Identification Of A Failed Engine In Twin-Engine Turboprop Aircraft, Andrey Babin, Andrew R. Dattel Ph.D.

National Training Aircraft Symposium (NTAS)

Previous incidents and accidents involving twin-engine aircraft, including the recent TransAsia Flight 235 crash, have revealed that pilots are prone to mistakes in identifying the engine that fails, and subsequently, shutting down the wrong engine, i.e. perfectly working engine. Most accidents of this type happen on takeoff when pilot workload is at its highest level. It may be that the current training procedure for engine failures on takeoff, called identify-verify-feather (IVF), is counterintuitive and may lead to greater confusion. IVF is based on haptic sensory channel, which is known to be less effective than visual channel. This study proposes a …
