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...

Objective. We examined the personality correlates of accident-proneness of autorickshaw drivers in the Indian city of Ranchi. Methods. This was a cross-sectional study in which 50 male drivers aged 18–50 years, selected randomly from a list of licensed autorickshaw drivers in Ranchi, were assessed with a Hindi version of Cattell’s 16 Personality Factors (16-PF) Questionnaire. Results. There was...

This report describes a Bayesian method for estimating accident rates at individual sites, which takes into account the fact that the total traffic count usually used to measure exposure is generally not known with certainty. The first step involves deriving an approximation for the probability distribution of total traffic conditioned on a short count sample. This approximation is then used to...

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 Negative Binomial modeling technique was used to model the frequency of accident occurrence and involvement. Accident data over a period of 3 years, accounting for 1,606 accidents on a principal arterial in Central Florida, were used to estimate the model. The model illustrated the significance of the Annual Average Daily Traffic (AADT), degree of horizontal curvature, lane, shoulder and me...

Injury characteristics of child passengers in accidents are summarized in this paper. Based on the accident data about child passengers from 2011 to 2017 collected in the National Automobile Accident In-Depth Investigation System (NAIS), the analysis of the patterns of the traffic accident where child passengers are involved and injury characteristics of child passengers in the aspects of crash...
