A paper titled “Meta-regressions of exposure parameters used in spatial road safety analyses, September 2020” authored by Apostolis Ziakopoulosand is now published in Advances in Transportation Studies. The objective of this paper is to obtain quantitative estimates that several study characteristics impose on the values of their coefficients applying meta-regression techniques to three common exposure parameters (traffic volume/AADT, roadway length and vehicle distance traveled). Results indicate that the impact of traffic volume on crash counts was positively correlated with taking speed limit and road user age into consideration in spatial analyses, while the impact of road length on crash counts in spatial analyses was found to be higher in studies considering only fatal crashes. doi

The Road Safety Screening and Appraisal Tool (RSSAT) is developed by the World Bank Global Road Safety Facility (GRSF) early ex-ante assessment of road safety conditions and associated economic impacts, which will apply to all new road infrastructure projects in the World Bank portfolio.  After successful trials in 2019-2020, use of the RSSAT is now required for all World Bank transport projects, and it is also recommended to be used for other operations that can have road safety impacts, such as urban and agriculture projects. Using the tool, project teams can evaluate road safety performance based on existing conditions and screen for safety improvement opportunities in road and roadside infrastructure. It is possible to estimate fatality rates under scenarios with and without the project, as well as the associated economic costs. In the following months, RSSAT will be also available to governments, development agencies, researchers, and other road safety professionals through an interactive GRSF web platform .

Implemented by the European Bank for Reconstruction & Development (EBRD) and  supported by the World Bank GRSF, an international experts team has developed the Occupational Road Risk Toolkit – a structured e-learning program in which fleet managers, drivers, and motorcycle riders can receive tailored content. This platform contains resources and free e-learning modules for different stakeholders to help manage risk across numerous road safety challenges. With this innovative tool, EBRD wants to improve the quality of management and vehicle fleet as well as the way in which road networks are used.

A paper titled “A descriptive analysis of the effect of the COVID-19 pandemic on driving behavior and road safety” authored by Christos Katrakazas, Eva Michelaraki, Marios Sekadakisand is now published in Transportation Research Interdisciplinary Perspectives. Driving behavior and safety indicators were captured through a specially developed smartphone application in two countries, namely Greece and Kingdom of Saudi Arabia (KSA). It was shown that reduced traffic volumes due to lockdown, led to a slight increase in speeds by 6–11%, but more importantly to more frequent harsh acceleration and harsh braking events (up to 12% increase) as well mobile phone use (up to 42% increase) during March and April 2020. doi

An NTUA Diploma Thesis titled “Acceptance of environmental transport charging policies” was recently presented by Asimina Korentzelou. This Diploma Thesis places emphasis on environmental charging (annual card) for private cars access in Athens center. On that purpose, data were collected through a questionnaire survey, using stated preference methodology. The results demonstrate that annual card cost and travel time savings are the main factors for the acceptance of the annual card. Furthermore, men, young people and high-income travelers are more likely to accept the annual card and environmental traffic policies. Finally, it was observed that the environmental awareness of drivers affects the acceptance of environmental traffic policies.  pdf5 ppt5

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
An NTUA Diploma Thesis titled “Preferences towards e-scooters in Athens” was recently presented by Vasilis Maragkoudakis. This Diploma Thesis identifies the most important factors affecting traveler modal choices in Athens. Logistic regression models were developed (multinomial and binary), which demonstrated that the probability of choosing an e-scooter depends largely on the cost, time, comfort, attitudes, habits and the demographic characteristics of the respondents. 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
