Studies investigating crash rates by roadway classification are few and far between and even more so if extended to focus on heavy vehicles. This study explores and compares two advanced econometric methods, random-parameter Tobit regression and latent class Tobit regression, to determine contributing factors for heavy vehicle crashes per million-vehicle-miles-traveled while accounting for the ...

BACKGROUND Traffic-related injuries are the most common cause of morbidity and mortality of the youth. Our aim was to study epidemiology, risk factors and outcome of hospitalized youth patients injured in road traffic collisions in order to give recommendations for prevention. METHODS We prospectively studied all youth (15-24 years) patients having traffic-related injuries who were admitted t...

1 Weaving is defined as the crossing of two streams travelling in the same direction along a 2 significant section of the road without the assistance of traffic control devices. Merging and 3 diverging vehicles need to make one or more lane-changes in a limited space and time, 4 determined by the weaving section length. This situation creates intensive lane-change 5 maneuvers, combined with hea...

Young inexperienced drivers are more likely to be involved in road traffic crashes than drivers who are older and more experienced. This paper argues that neither age nor inexperience are, in and of themselves, sufficient explanations of the association between age, experience, and casualty rates. The aim here is to consider what it is about inexperienced young drivers in particular that may in...

This paper presents the use of the Aimsun microsimulation program to simulate vehicle violating behaviors and observe their impact on road traffic crash risk. Plugins for violations of speeding, slow driving, and abrupt stopping were developed using Aimsun's API and SDK module. A safety analysis plugin for investigating probability of rear-end collisions was developed, and a method for analyzin...

Introduction: This study presents a classification tree based alternative to crash frequency analysis for analyzing crashes on mid block segments of multilane arterials. Method: The traditional approach of modeling counts of crashes that occur over a period of time works well for intersection crashes where each intersection itself provides a well defined unit over which to aggregate the crash d...

Given the increasing vehicle numbers and expanding road construction in developing countries, the importance of safe road user behaviour is critical. Road traffic crashes (RTCs) are a significant problem in Pakistan; however, the factors that contribute to RTCs in Pakistan are not well researched. Fatalistic beliefs are a potential barrier to the enhancement of road safety, especially participa...

15. Supplementary Notes Supported by general revenues from the State of Texas 16. Abstract In recent years, there has been a renewed interest in applying statistical ranking criteria to identify sites on a road network, which potentially present high traffic crash risks or are overrepresented in certain type of crashes, for further engineering evaluation and safety improvement. This requires th...
