Modelling self-reported driver perspectives and fatigued driving via deep learning, November 2021

A paper titled “Modelling self-reported driver perspectives and fatigued driving via deep learning” authored by Alexandros ZouposApostolos Ziakopoulos and George Yannis is published in Traffic Safety Research.  A binary logistic regression model was trained to provide causal insights on which variables affect the likelihood that a driver engaged in driving while fatigued, whereas a Deep Neural Network (DNN) was subsequently trained on the data, slightly outperforming the binary logistic model. Results demonstrate that drivers reporting driving under the influence of drugs, fatigue, or alcohol, as well as speeding, safety, and texting while driving or drivers who were more acceptable of fatigued driving were more likely to have recently driven while fatigued, and from the results of this paper it was concluded that declared fatigued driving behavior can be predicted from questionnaire data, providing new insights to fatigue detectiondoi

Analysis of the impact of COVID-19 on collisions, fatalities and injuries using time series forecasting: The case of Greece, November 2021.

A paper titled “Analysis of the impact of COVID-19 on collisions, fatalities and injuries using time series forecasting: The case of Greece“, authored by Marios SekadakisEva MichelarakiChristos Katrakazas and  is  published in Accident Analysis & Prevention. Three different Seasonal Autoregressive Integrated Moving Average (SARIMA) time series models were implemented on road casualties data for the period 2010-2020 in order to compare the observed measurements to forecasted values intended to depict assumed conditions; namely, without the appearance of the COVID-19 pandemic. The results demonstrate that fatalities and slightly injured rates were significantly increased during the lockdown period and the subsequent months. Overall, it can be concluded that a worse performance was identified in terms of road safety. Since subsequent waves of COVID-19 cases and other pandemics may reappear in the future, the outcomes of the current study may be exploited for the improvement of road safety from local authorities and policymakers. doi

Comparative analysis of road safety factors across generations, in Greece, July 2021

An NTUA Diploma Thesis titled “Comparative analysis of road safety factors across generations, in Greece” was recently presented by Reggina Mermiga. From the application of Log-Linear regression models it emerges that the number of road casualties follows a rising trend in the transition from the older to the younger generations, which presumably can be attributed to increased mobility of younger generations. Additionally, most car crash victims between the ages of 26 and 64 belong to Generation X while those involved in a two-wheeled vehicle accident belong to Generation Y, most probably due to the fact that the members of the two generations are connected to different financial periods but also to the tendency of the members of Generation Y to experience delays in their transition to the following stages of their life. pdf5 ppt5

Which factors lead to driving errors? A structural equation model analysis through a driving simulator experiment, April 2019

A paper titled “Which factors lead to driving errors? A structural equation model analysis through a driving simulator experiment” authored by Panagiotis PapantoniouGeorge Yannis and Eleni Christofa is published in Journal of IATSS. Data were obtained from a driving simulation experiment in which 95 participants covering all ages were asked to drive under different types of distraction (no distraction, conversation with passenger, cell phone use) in rural and urban road environment, as well as in both low and high traffic conditions. Structural Equation Models were developed and the driving error was modeled as a latent variable based on several individual driving simulator parameters. The results of this complex model reveal that the impact of driver characteristics and area type are the only statistically significant factors affecting the probability of driving errors. Interestingly, neither conversing with a passenger nor talking on the cell phone have a statistically significant impact on driving error behaviour which highlights the importance of the present analysis and more specifically the development of a measure that represents overall driving error behaviour instead of individual driving errors variables. doi

Impact of pandemic to mobility behavior in the European Union using time-series analysis, March 2021.

An NTUA Diploma Thesis titled “Impact of pandemic to mobility behavior in the European Union using time-series analysis” was recently presented by Marianthi Kallidoni. This Diploma Thesis revealed that school closing is the most important exogenous factor for describing driving or walking, while the effect of “Stay at home” orders was not a significant factor for the evolution of people movements. In addition, countries which suffered the most due to the pandemic showed a strong correlation with the restrictive measures. Furthermore, no time-series models were found to describe the countries which implemented weak countermeasures. pdf5 ppt5

Time Series Analysis of Vehicle and Pedestrian Traffic in Athens, March 2021.

An NTUA Diploma Thesis titled “Time Series Analysis of Vehicle and Pedestrian Traffic in Athens” was recently presented by Nick Economou. The result of this Diploma Thesis is that from summer onwards the forecasted mobility evolution of drivers and pedestrians in Athens Great Area is lower than the observed one, which may be due to summer holidays and high temperatures during summer months in which the prediction was based. Considering the modal split on the examined roads in the center of Athens, it is observed a reduction in the use of passenger vehicles with a simultaneous increase in the use of taxis, which may be due to the adaptation of drivers to the new traffic conditions of the Panepistimiou street brought about by the Athens Great Walk pilot operation. pdf5 ppt5

Impact of weather conditions and rush on road safety, March 2021.

An NTUA Diploma Thesis titled “Impact of weather conditions and rush on road safety” was recently presented by Giota Spanou. Data of 42 young drivers were collected, from a driving simulator experiment with and without any time pressure in good weather conditions, in fog, rain, and snow. Linear and binomial logistic regression models were developed for the mean driving speed, reaction time, headway and accident probability. The application of the mathematical models showed that snow and rain lead to a significant increase in the probability of an accident. Fog increases the accident probability only in the event of a dangerous event and time pressure seems to have the same effects as snow, a fact that should concern drivers.  pdf5 ppt5

Apostolos Ziakopoulos defended his PhD Thesis on Spatial Analysis of Road Safety and Traffic Behaviour using High Resolution Multi-parametric Data, July 2020

Apostolos Ziakopoulos has successfully defended his PhD dissertation titled: Spatial Analysis of Road Safety and Traffic Behaviour using High Resolution Multi-parametric Data. This PhD thesis was carried out at the Department of Transportation Planning and Engineering at the School of Civil Engineering of the National Technical University of Athens under the supervision of Prof. George Yannis, using data from OSeven Telematics.

The main objective of this PhD Dissertation is the spatial analysis of harsh event frequencies in road segments using multi-parametric data, including (i) high resolution naturalistic driving and driver behavior data from smartphone sensors, (ii) microscopic road segment geometry and road network characteristic data from digital maps and (iii) high resolution traffic data. Spatial analyses were performed on two parallel pillars: (i) Prediction models were developed in an urban road network training area, with the intent to transfer them to a second urban road network testing area and assess their predictive performance and (ii) Causal models including road user behavior and traffic input data were calibrated in an urban arterial study area per traffic state, in order to investigate additional underlying correlations in an effort to further understand the phenomena of harsh braking and harsh acceleration frequencies. Geographically Weighted Poisson Regression (GWPR) models, Bayesian Conditional Autoregressive Prior (CAR) models and Extreme Gradient Boosting algorithms with random cross-validation (RCV XGBoost) and spatial cross-validation (SPCV XGBoost) were implemented. pdf5 ppt5

The faster and the more economical is the trip and the more familiar is the traveler with e-scooters is, the more likely he/she is to choose them over other means of transport.  pdf5 ppt5

Event identification based on driving characteristics on rural roads, July 2020

An NTUA Diploma Thesis titled “Event identification based on driving characteristics on rural roads” was recently presented by Akrivi Varela. Focus was put on determining the main factors that can describe the situation before and during an event. Results showed that random forest model performs much better than the binomial logistic regression model in identifying event occurrence with very few false alarms. Moreover, speed and longitudinal acceleration along with total distance driven from the beginning of the driving session, turned out to better describe the case of driving one minute prior to an event. Finally, driving during an event can be sufficiently described through speed, the deviation of the vehicle from the middle of the road as well as time headway with the vehicle ahead.  pdf5 ppt5
