Fixed and random-parameters models were developed in this paper for total crashes (accidents involving material damage, injuries and/or fatalities) occurred within road tunnels. Separate models for unidirectional and bidirectional tunnels are proposed. For unidirectional road tunnels, it was found that the crash frequency is positively associated in a non-linear way with the tunnel length (L) a...

This paper aims at investigating brain injury mechanisms in adult pedestrian accidents by indepth accident analysis and accident reconstructions. In total, 120 adult pedestrian accident cases from the GIDAS database were analysed and 10 of them were reconstructed. The accident reconstructions were first carried out using multi-body system (MBS) pedestrian and car models to acquire the head impa...

The rapid population growth and increasing economic activities have resulted in the tremendous growth of motor vehicles which is considered one of the primary factors responsible for increasing road accidents in many metropolitan cities of developing countries, including Kolkata, India. In this paper an assessment of the current level of road safety in Kolkata is made utilizing data obtained fr...

The objective of the present work is to determine the effect of the vehicle front design on pedestrian head impact responses and injury related parameters based on accident reconstructions and simulation analyses of carpedestrian impacts. The accident reconstructions were carried out using selected accident data from an in-depth study with headbrain injuries documented in accident and medical r...

The issue of road accidents is an increasing problem in developing countries. This could be due to increasing road traffic/vehicle occupancy. This has been increasing over years. Regulating traffic on roads is an important task. There by reducing accidents in accident prone zones. The accident was drastically increased over a decade from 4% to 31%. This is a alarming issue. The analysis and ide...

Using data on work accidents and annual mining statistics, the paper studies work-related accidents in the Spanish energetic mining sector in 1999-2008. The following 3 parameters are considered: age, experience and size of the mine (in number of workers) where the accident took place. The main objective of this paper is to show the relationship between different accident indicators: risk index...

background and aim: traffic accident is one of the main causes of mortality in iran. the damage and injury caused by these accidents threatens human societies severely. rural accidents are often more severe and show harsher consequences because the operational speed is higher on rural roads and highways. world statistics presented by world health organization (who) reveal that about 25 percent ...

The problem of traffic accidents in Indonesia has a high level risk. In an effort to minimize losses due accidents, it is necessary study the data and characteristics identify these events as extreme events. This was conducted find out how estimate shape scale parameters using Maximum Likelihood Estimation (MLE), explore on accident Indonesia. method used analyze value Extreme Value Theory. One...
