Traffic accident data are often heterogeneous, which can cause certain relationships to remain hidden. Therefore, traffic accident analysis is often performed on a small subset of traffic accidents or several models are built for various traffic accident types. In this paper, we examine the effectiveness of a clustering technique, i.e. latent class clustering, for identifying homogenous traffic...

The term accident proneness was coined by psychological research workers in 1926. Since then its concept-that certain individuals are always more likely than others to sustain accidents, even though exposed to equal risk-has been questioned but seldom seriously challenged. This article describes much of the work and theory on which this concept is based, details the difficulties encountered in ...

Increasing amount of road traffic in 1990s has drawn much attention in Korea due to its influence on safety problems. Various types of data analyses are done in order to analyze the relationship between the severity of road traffic accident and driving environmental factors based on traffic accident records. Accurate results of such accident data analysis can provide crucial information for roa...

The need of in-depth accident causation data in accident research is becoming more and more important. The German In-Depth Accident Study GIDAS is well qualified to deliver adequate data to conduct an investigation on this field, based also on identifying the causes of accidents. This led to the development and implementation of a special tool called ACAS (Accident Causation Analysis System) fo...

Procedural modeling is a method that determines production rules and allows for developing effective structural design in architecture. Fountain (Shadirvan) an important component of Turkish architecture having symmetrical structure distinctive elements makes fountains suitable procedural modeling. In this study, we propose to different fountain models similar ones exist We specify the paramete...

many studies have been conducted focusing on the effects of friction coefficient or texture depth on the highway accident risk. however, combined effects of these parameters have not been still addressed. in this research the interaction between friction coefficient, texture depth and accident rate in 30 freeway sections were examined. the accident data were gathered and an apparatus was design...
