Dr Ashleigh Filtness
Senior Research Associate
Dr Ashleigh Filtness is a Senior Research Associate within the Transport group at Loughborough Design School She specialises in road safety and driver behaviour, with particular expertise in driver sleepiness, impaired driving and using driving simulators for research.
Ashleigh was awarded her PhD from Loughborough University in 2011 for her thesis entitled Obstructive sleep apnoea and daytime driver sleepiness. This research used a driving simulator methodology to demonstrate the increased vulnerability of obstructive sleep apnoea patients driving performance to sleep restriction, and impairment of their driving performance following one night of treatment withdrawal. For her work in this area, Ashleigh was recognised as the British Sleep Societies Young Sleep Researcher of the Year – 2009.
Following the completion of her PhD, Ashleigh moved to Australia where she worked at Monash University Accident Research Centre (MUARC) for two years. Whilst at MUARC, Ashleigh worked on a variety of road safety research projects funded by both industry and competitive grant schemes. She gained experience in a range of research methodologies including extending her knowledge of driving simulators and developed expertise in various road safety topics, including: systems thinking, driver distraction, situation awareness, alcohol impairment with motorcycle riders, police in-vehicle safety, the management of heavy vehicle drivers working hours, and driver behaviour at level crossings.
From 2013-2016 Ashleigh worked at Queensland University of Technology, Centre for Accident Research and Road safety – Queensland (CARRS-Q) working on government, industry and grant funded research projects. During her time at CARRS-Q Ashleigh worked on road safety research projects covering topics in the following areas: driver sleepiness, novice driver training, drug driving, drink driving, driver aggression, driver behaviour in road work sites, safety implications for co-locating road signs, alcohol ignition interlocks, taxi crashes, rail level crossing safety and hot air ballooning incident analysis.
Since completing her Ph.D Ashleigh has authored over 30 peer reviewed publications and attracted research funding totalling over $1 million (AUD) from government, industry and competitive grant schemes.
SafetyCube (Safety CaUsation, Benefits and Efficiency) research project, funded by the European Commission under the Horizons 2020, the EU Framework Programme for Research and Innovation, in the domain of Road Safety.
The primary objective of the SafetyCube project is to develop an innovative road safety Decision Support System (DSS) that will enable policy-makers and stakeholders to select and implement the most appropriate strategies, measures and cost-effective approaches to reduce casualties of all road user types and all severities in Europe and worldwide.
Recent research projects:
- Developing and evaluating a theoretically grounded novice driver education program incorporating simulators.
- Effects of sleep loss on change detection while driving.
- Caffeine and rear-end crashes in urban driving; developing a new test paradigm.
- Human factors in Transport Exchange Program: Fatigue and SPAD risk.
- Understanding sleepy drivers: towards development of a targeted intervention.
