PhD title

PhD #14  Road safety prediction on the basis of ethically sound physiological measurements

Vacancy description

Within the IVORY doctoral network, this PhD position aims to understand and predict how the psychophysiological state of the driver contributes to overall road safety, particularly by using measurements of physiological data, such as the electrocardiogram (ECG), photoplethysmogram (PPG), blood pressure, among others. The goal is to create machine learning models that relate individual physiological dynamics with road safety indicators, with the ultimate objective of accurately and reliably detecting and warning, in real-time, when the driver is unfit for the driving task, regardless of automation level. Deep learning methodologies, such as convolutional neural networks, should be considered, as well as privacy-by-design frameworks.

The position contributes to road safety research by compiling a taxonomy of driver monitoring technologies, creating innovative algorithms for physiological-based, real-time prediction of driver capability and its impact on safety, in several real-world scenarios, and to explore and create frameworks to assess the ethical and privacy dimensions of the use of driver monitoring technologies.

The impact of cognition-affecting neurological diseases on reaction time and driving speed deviation, June 2023

A paper titled “The impact of cognition-affecting neurological diseases on reaction time and driving speed deviation” authored by Athina DiamantiApostolos Ziakopoulos and George Yannis, has been published in Open Transportation Journal. Analysis of cognitive impairments based on GDS questions showed that frequent ‘feelings of boredom’ correlated with a 7% increase in reaction time and a 8% increase in the standard deviation of driving speed. Conversely, ‘feelings of worthlessness’ reduced the standard deviation of driving speed by 4.5%. Drivers with Alzheimer’s and Parkinson’s diseases showed higher reaction times, while drivers with depression and the control group showed lower reaction times. Drivers with Parkinson’s disease showed statistically fewer deviations of average speed. This research demonstrated that cognitively impaired individuals have larger reaction times and more erratic driving speeds.  doi

An Evaluation of the Passing Process through Road – Vehicle Parameters Assessment, March 2023

A paper titled “An Evaluation of the Passing Process through Road – Vehicle Parameters Assessment” authored by Stergios Mavromatis, Vassilios Matragos, Konstantinos Apostoleris, Fotios Fotos and George Yannis, has been published in European Transport Research Review. The methodology is based on a realistic representation of the passing task with respect to roadway’s posted speed and the ability of the passing (examined) vehicle to perform such maneuvers. The analysis revealed that the difference between the speed of the passed vehicle and the posted speed value, as well as certain interactions of the assessed parameters impact excessively passing sight distances (PSDs), especially for values below 20 km/h. The lognormal modelling approach for predicting PSDs was found efficient and may be useful to researchers and practitioners aiming to evaluate the interaction of the utilized road—vehicle parameters in terms of determining PSDs as well as passing zones. doi

Investigation of traffic and safety behavior of pedestrians while talking on mobile phone, June 2022

A paper titled “Investigation of traffic and safety behavior of pedestrians while talking on mobile phone” authored by Dimitra Typa, Dimitris Nikolaou and George Yannis, has been published in Advances in Transportation Studies. This study aims to investigate how hand-held cell phone conversation affects the behavior of pedestrians at signalized intersections in terms of both safety and traffic. In order to compare the behavior of distracted and non-distracted pedestrians, an outdoor environment experiment was carried out in real road conditions. Various demographic and behavioral characteristics were recorded, including mobile phone use. Initially, multiple linear regression models were developed in order to identify how cell phone use affects pedestrians’ speed. The results of the developed statistical models showed that pedestrians’ main traffic and safety characteristics were negatively impacted by distraction from hand-held cell phone conversation, as mobile phone use not only reduces pedestrians’ speed but also increases the likelihood that they will be involved in a collision with an approaching vehicle. doi
