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

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

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

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

Analysis of pedestrians distracted behaviour talking on mobile phone, 2019

A Diploma Thesis titled “Analysis of pedestrians distracted behaviour talking on mobile phone” was recently presented by Dimitra Typa. The aim of this Diploma Thesis was to investigate the impact of hand-held cell phone conversation on pedestrians’ traffic and safety behaviour, when crossing signalized intersections. An outdoor-environment experiment, through video recording, was conducted in real road conditions, in three signalized intersections at the centre of Athens for the purpose of comparing the behaviour of distracted and non-distracted pedestrians. The results of the models’ application demonstrated that distraction caused by hand-held cell phone conversation had a negative impact on pedestrians’ main traffic and safety characteristics, since, in general, mobile use not only decreases pedestrians’ speed but also increases their probability of being involved in an accident with an oncoming vehicle. pdf5 ppt5

Driving Safety Efficiency Benchmarking Using Smartphone Data, 2019

A paper titled “Driving Safety Efficiency Benchmarking Using Smartphone Data” authored by Dimitrios Tselentis, Eleni Vlahogianni, and George Yannis is now published in Transportation Research Part C: Emerging Technologies. This paper aims to provide a methodological framework for the comparative evaluation of driving safety efficiency based on Data Envelopment Analysis (DEA). The analysis considers each driver as a Decision-Making Unit (DMU) and aims to provide a relative safety efficiency measure to compare different drivers based on their driving performance. The proposed methodological framework is tested on data from fifty-six (56) drivers during a 7-months period. Findings help distinguish the most efficient drivers from those that are less efficient. Most common inefficient driving practices are identified (aggressive, risky driving, etc.) and driving behaviour is comparatively evaluated and analyzed. doi
