The Hellenic Ministry of Infrastructure and Transport produced for the first time ever Road Safety Key Performance Indicators (KPIs) for all key crash risk factors in Greece, with the active contribution of NTUA. The five KPIs related to road user behavior concern speeding, seatbelt use, helmet use, driving under the influence of alcohol and distraction and demonstrate the basic causes of road crashes in Greece. These KPIs have been incorporated at the new National Road Safety Plan of Greece in order to identify key road safety problems in Greece and to determine the respective solutions, but also for the setting of the 8 road safety KPI targets for the decade (e.g. helmet wearing rate from 79% today, to 90% in 2025 and 95% in 2030).
An NTUA Diploma Thesis titled “Cost benefit and acceptance analysis of reducing speed limits in Athens to 30km/h” was recently presented by Stella Roussou. This Diploma modeled Athenians preferences on speed limit reduction and performed the respective socio-economic cost benefit analysis (CBA) of the reduction of crashes and respective casualties, the costs incurred due to the increase in travel time and the benefit from reducing fuel consumption and environmental impact (CO2, NOx, PM emissions). The CBA revealed that the 30km/h speed limit is deemed economically highly viable and worth of implementing.
The Horizon 2020 project i-DREAMS (smart Driver Environment Assesment and Monitoring System) recently released its 5th Newsletter, presenting the main accomplishments of the project, through creative solutions and risk mitigation strategies, exploiting state-of-the art findings on driver safety tolerance zone. The Newsletter presents how to bring i-DREAMS to the market and society, the second successful review meeting and several i-DREAMS dissemination activities.
The Ministry of Infrastructure and Transport developed the National Road Safety Strategic Plan for the period 2021-2030, with the scientific support of the Department of Transport Planning and Engineering of the National Technical University of Athens (NTUA). The National Road Safety Strategic Plan 2021-2030 exploits state-of-the-art international experience and good practice, adjusted to the Greek reality and contains a set of 44 actions and 200 measures with concrete budget and timeplan addressing the key road safety problems in Greece: speeding and motorcycle traffic; aiming to meet the quantitative targets set for the reduction of the number of fatalities and serious injuries in road crashes by 50% by 2030. Within the current final open consultation process you are welcome to submit your remarks and comments.
Modelling the relationship between covid-19 restrictive measures and mobility patterns across Europe using time-series analysis, May 2022
A paper titled “Modelling the relationship between covid-19 restrictive measures and mobility patterns across Europe using time-series analysis” authored by Marianthi Kallidoni, Christos Katrakazas and George Yannis is published in European Journal of Transport and Infrastructure Research. Data on walking and traffic were exploited and several time series analysis models were developed, in order to estimate mobility during pandemic in 25 EU countries. School closing was found to be the most important exogenous factor for describing driving or walking, while “Stay at home” orders had not a significant effect on the evolution of people movements.
