Integrating rough sets with neural networks for weighting road safety performance indicators (2009)
Li, Tianrui, Shen, Youngjun, Ruan, Da, Hermans, Elke, Wets, Geert
This paper aims at improving two main uncertain factors in neural networks training in developing a composite road safety performance indicator. These factors are the initial value of network weights...
Evaluation of road safety performance indicators using OWA operators (2008)
Hermans, Elke, Ruan, Da, Brijs, Tom, Wets, Geert, Vanhoof, Koen
Road safety performance indicators have recently been proposed as a useful instrument in comparing countries on their performance of road safety risk factors. New insights can be gained in case one...
Combining road safety information in a performance index (2008)
HERMANS, Elke, VAN DEN BOSSCHE, Filip, WETS, Geert
In this paper we focus on an essential step in the construction process of a composite road safety performance indicator: the assignment of weights to the individual indicators. In the composite...

Impact of Methodological Choices on Road Safety Ranking (2008)
HERMANS, Elke, VAN DEN BOSSCHE, Filip, WETS, Geert
Composite indicators aggregate a lot of information in one index based on which countries are often ranked. However, the position of a country can largely be influenced by the methodological choices...
HERMANS, Elke, BRIJS, Tom, WETS, Geert
Het aantal letselongevallen en slachtoffers wordt vaak vergeleken tussen landen om een idee te krijgen van de relatieve prestatie inzake verkeersveiligheid. Het is echter zinvol om daarnaast de...
HERMANS, Elke, WETS, Geert, VAN DEN BOSSCHE, Filip
The general purpose of this research is to improve the insight in road safety on Belgian highways by means of a layered model. In this study, the monthly number of persons killed on highways in...
The Impact of Weather Conditions on Road Safety Investigated on an Hourly Basis (2006)
HERMANS, Elke, BRIJS, Tom, Stiers, T, Offermans, C
In this paper we investigate the impact of several weather conditions on the hourly number of crashes in the Netherlands during 2002. The impact of 17 climatic factors, belonging to the categories...
Frequency and Severity of Belgian Road Traffic Accidents Studied by State-Space Methods (2006)
HERMANS, Elke, WETS, Geert, VAN DEN BOSSCHE, Filip
In this paper we investigate the monthly frequency and severitiy of road traffic accidents in Belgium from 1974 to 1999. We describe the trend in the time series, quantify the impact of explanatory...
Verkeersonveiligheid voor de zwakke weggebruiker in Vlaanderen (2006)
HERMANS, Elke, WETS, Geert, VAN DEN BOSSCHE, Filip
In deze bijdrage wordt de veiligheid van de zwakke weggebruiker in het verkeer belicht. Uit de statistieken blijkt dat voetgangers en fietsers de meest kwetsbare groepen van weggebruikers zijn en in...

Benchmarking road safety: Lessons to learn from a data envelopment analysis
Hermans, Elke, Brijs, Tom, Wets, Geert, Vanhoof, Koen
Road safety performance indicators (SPI) have recently been proposed as a useful instrument in comparing countries on the performance of different risk aspects of their road safety system. In this...
Uncertainty assessment of the road safety index
HERMANS, Elke, VAN DEN BOSSCHE, Filip, WETS, Geert
Composite indicators aggregate domain-specific information in one index, on the basis of which countries can be assigned a relative ranking. Recently, the road safety community got convinced of the...
