Background
Since 1994, the legal limit of Blood Alcohol Concentration (BAC) is 0.5 g/L for the general drivers’ population in Belgium. Since 2015, this limit has been lowered to 0.2 g/L for professional drivers. So far, no specific limitation has been adopted for novice drivers in Belgium. Recently, two bills were submitted to the House of Represen...
Economic evaluations of road safety measures are only rarely published in the scholarly literature. We collected and (re-)analyzed evidence in order to conduct cost-benefit analyses (CBAs) for 29 road safety measures. The information on crash costs was based on data from a survey in European countries. We applied a systematic procedure including co...
This paper gives an overview of official monetary valuations of the prevention of road crashes, road fatalities and injuries in 31 European countries. The values have been made comparable by converting them to Euro in 2015-values, adjusted by purchasing power parities. The monetary valuation of preventing a fatality varies from 0.7 to 3.0 million E...
The European Road Safety Decision Support System (roadsafety-dss.eu) is an innovative system providing the available evidence on a broad range of road risks and possible countermeasures. This paper describes the scientific basis of the DSS. The structure underlying the DSS consists of (1) a taxonomy identifying risk factors and measures and linking...
At the end of each year, the German Federal Highway Research Institute (BASt) publishes the road safety balance of the closing year. They describe the development of accident and casualty numbers disaggregated by road user types, age groups, type of road and the consequences of the accidents. However, at the time of publishing, these series are onl...

The monthly road traffic accident victim numbers in Belgium (2003-2014) were analyzed in latent trend time series models separately for pedestrians, cyclists, moped riders, car occupants and road user types jointly. For each road-user type the effect of a range of meteorological variables was tested. The resulting models allow a detailed view on th...
In 2011, traffic filtering of motorcyclists was legalized in Belgium under certain conditions. To evaluate
the effect of this measure, motorcycle accidents before the measure (2009-2010) and after the
measure (2012-2013) where compared with respect to their distribution across the type of road (motorway,
urban, rural), type of accident (single vehi...
Background
The European Road Safety Decision Support System (DSS) is one of the key objectives of the European co-funded research project SafetyCube in order to better support evidence-based policy making. The SafetyCube project results will be assembled in the form of a Decision Support System that will present for each suggested road safety measu...
This chapter presents the European Road Safety Knowledge System, which was developed within the Data Collection Transfer and Analysis (DaCoTA) research project of the 7th Framework Program of the European Commission. This knowledge system includes a number of components, concerning data and tools, road safety issues and countries. A three-step meth...
This chapter presents the analysis of a road safety management framework in European countries and the identification of “good practice” for the optimization of road safety management processes, carried out within the DaCoTA research project. It then discusses the road safety management investigation model, and describes the data collection and han...
This study investigated the influence of alcohol checks and social norm on self-reported driving under the influence of alcohol above the legal limit (DUI). The analysis was based on the responses of 12,507 car drivers from 19 European countries to the SARTRE-4 survey (2010). The data were analysed by means of a multiple logistic regression-model o...
In this paper a unified methodology is presented for the modelling of the evolution of road safety in 30 European countries. For each country, annual data of the best available exposure indicator and of the number of fatalities were simultaneously analysed with the bivariate latent risk time series model. This model is based on the assumption that...
The European Road Safety Observatory was established European Commission and first announced in the 2001 Transport White Paper1. It was further developed in the 2003 Road Safety Action Plan 2 where the Commission announced it was to establish a new European Road Safety Observatory (ERSO) to "co-ordinate all Community activities in the fields of roa...
Hierarchical structures in road safety data are receiving increasing attention in the literature and multilevel (ML) models are proposed for appropriately handling the resulting dependences among the observations. However, so far no empirical synthesis exists of the actual added value of ML modelling techniques as compared to other modelling approa...
The difference between single vehicle crashes and multivehicle crashes was investigated in a collection of fatal crashes from six European countries. Variables with respect to road conditions, time variables, and participant characteristics were studied separately at first and then jointly in a logistic multiple regression model allowing to weigh d...
The objective of this research is the assessment of current needs for evidence-based road safety decision making in Europe, through the consultation of a panel of road safety experts. The members of this Experts Panel have extensive knowledge of road safety management processes and needs in their country, being either directly involved in decision...
The work package 1 of the EC FP7 project DaCoTA investigates road safety management processes in Europe. It has drafted a model to investigate the state of the art of road safety policy-making and management at the national level and to define "good practice". The DaCoTA "good practice" investigation model recommends no "one-best-way" solutions, ei...
Phonologicalconsistency describes to what extent a letter string in one word is pronounced equally in other words. Phonologicalreliability describes to what extent a sublexical unit is usually consistent throughout a language. The relationship between the two
concepts was investigated by comparing five sublexical units (onset-consonants, vowel, end...
Buchner, Erdfelder, Steffens, and Martensen (1997) proposed that the memory processes involved in recognition judgments in
the process dissociation procedure are the same as those involved in standard source monitoring tasks. Two extensions of that
research are presented here. First, following a line of reasoning recently brought forward by Jacoby...
The aim of the DaCoTA Work Package 1 is to investigate road safety policy-making and management processes in Europe. In the Deliverables released previously, the Work Package 1 assessed the experts' needs in terms of road safety knowledge, data and decision support tools (Deliverable 1.1/4.1), as well as the road safety stakeholders' views (Deliver...
The aim of DaCoTA's Work Package 1 is to shed light on road safety policy-making and management processes in Europe and to explore how these can be better supported by data and knowledge. This was done by assessing demands and views of stakeholders as well as by building a good practice model for road safety management investigation. Future version...
In this article the factors affecting fatality and injury risk of road users involved in fatal accidents are analyzed by means of in-depth accident investigation data, with emphasis on parameters not extensively explored in previous research.
A fatal accident investigation (FAI) database is used, which includes intermediate-level in-depth data for...
This paper aims at addressing the interest and appropriateness of performing accident severity analyses that are limited to fatal accident data. Two methodological issues are specifically discussed, namely the accident-size factors (the number of vehicles in the accident and their level of occupancy) and the comparability of the baseline risk. It i...
Dutch-English participants named words and nonwords having a between-language phonologically inconsistent rime, e.g., GREED and PREED, and control words with a language-typical rime, e.g., GROAN, in a monolingual stimulus list or in a mixed list containing Dutch words. Inconsistent items had longer latencies and more errors than typical items in th...
To assess the role of the subsyllabic units onset-nucleus (ON; spark) and rime (spark) in Dutch visual word recognition, we compared lexical decisions to four groups of nonwords in which the existence of ONs and rimes was orthogonally manipulated. Nonwords with existent ONs and/or rimes were rejected more slowly and less accurately. ON and rime nei...
To investigate decision level processes involved in bilingual word recognition tasks, Dutch–English participants had to name Dutch–English homographs in English. In a stimulus list containing items from both languages, interlingual homographs yielded longer naming latencies, more Dutch responses, and more other errors in both response languages if...
Geudens and Sandra, in their 2003 study, investigated the special role of onsets and rimes in Dutch-speaking children's explicit phonological awareness. In the current study, we tapped implicit phonological knowledge using forced-choice similarity judgment (Experiment 1) and recall of syllable lists (Experiment 2). In Experiment 1, Dutch-speaking p...
To establish the relative contribution of phonological and orthographic information to visual word recognition, we varied the instruction how to respond to the pseudohomophones in a Dutch lexical decision task. One participant group was asked to base their word/nonword decisions on spelling and therefore reject pseudohomophones together with the no...
The lexical bias effect is the tendency for phonological speech errors to result in words more often than in nonwords. This effect has been accounted for by postulating feedback from sublexical to lexical representations, but also by assuming that the self-monitor covertly repairs more nonword errors than word errors. The only evidence that appears...
In one lexical decision and three naming experiments, we established the effect of visually separating two letters that have to be considered jointly for pronunciation. Segmentation effects were studied for digraphic vowels and for ambiguous onset-letter (C) whose pronunciation is determined by the following vowel. Separating the two letters of a d...
The hypothesis is tested that the memory processes involved in recognition judgments in the process dissociation procedure
are the same as those involved in standard source-monitoring tasks. It is shown how source-monitoring response categories
can be mapped onto process dissociation response categories. On the basis of this observation, an experim...
Road safety analyses aim to describe and explain road safety outcomes (road accidents and casualties), either in time or in space, as well as to forecast future developments on the basis of existing experience. The availability of reliable data is one of the most important conditions for useful road safety analyses. Within the development of the Eu...
