Abstract Johor is one of the states in Malaysia that records high accident statistics, especially on Federal Route FT050, Batu Pahat-Ayer Hitam. One elements causing an attitude a driver who drives too fast and ignores warning speed limit signs. The study aimed to determine whether signboard’s impact driving at before- after-study locations. GPS DG 200 was used record data 50 trips Pahat Ayer D...

In this study, two-state Markov switching count data models are proposed as an alternative to zero-inflated models, in order to account for preponderance of zeros typically observed in accident frequency data. Similar to zero-inflated models, two-state Markov switching models assume an existence of two states of roadway safety. One of the states is a zero-accident state, which is safe. The othe...

One of the many difficulties in the study of accident causation is to keep under detailed medical supervision a group of men exposed to constant risk who provide a sufficiently large number of apparently accident-prone individuals. At the end of 1944 the prospects of continued employment were good. In an area where there was little alternative employment available, 300 men, who in that year had...

Log-linear modeling is advanced as a procedure to identify factors that underlie the relative frequency of occurrence of various accident characteristics, such as accident type, location, and severity. The method is centered on the estimation of saturated log-linear models for pairs of accident variables and determination of indices of association between categories of the variables. Using data...

The transportation of dangerous goods by road is the most accident-prone mode transportation, even if accidents involving are considered as a Low Probability and High Consequence event (LPHC event). However, several transported networks, such petroleum products chemicals, which can generate major consequences spills, explosions, fires, or toxic clouds. In this context, article presents method t...
