Modeling Socio-Economic Determinants Of Traffic Fatalities, Amin Azimian, Deogratias Eustace May 2019

Modeling Socio-Economic Determinants Of Traffic Fatalities, Amin Azimian, Deogratias Eustace

Deogratias Eustace

Over several decades, traffic growth has caused an increased number of traffic crashes, which are associated with economic losses and human sufferings. According to the National Highway Traffic Safety Administration [1] in 2016 there were a total of 34,247 fatal traffic crashes in the United States that resulted into 37,133 fatalities. Risk factors relating to the occurrence of fatal and injury severity of motor vehicle crashes have been extensively studied. Most studies [2-7] that have attempted to model the occurrences of traffic crashes and fatalities have been mainly confined to factors related to driver characteristics, roadway geometry characteristics, traffic characteristics, …


Evaluation Of The Role Of Driver’S Knowledge Of Who Has The Right-Of-Way Contributes To Interstate On-Ramp Crashes, Deogratias Eustace, Vamsi Krishna Indupuru Jan 2018

Evaluation Of The Role Of Driver’S Knowledge Of Who Has The Right-Of-Way Contributes To Interstate On-Ramp Crashes, Deogratias Eustace, Vamsi Krishna Indupuru

The knowledge of drivers on who has the right-of-way between the one on mainline lanes of a freeway and the one entering the freeway through on-ramp junction lane was evaluated. In addition, drivers’ opinions on how to make the on-ramp junctions safer were collected. A survey instrument with 21 items requesting drivers’ information in regard with demographics, freeway driving experience, knowledge of right-of-way and merging practices was used for data collection. The results show that crashes are relatively rare events and for some reasons, most of them never happen but result into near misses, which can not be reported and …


Performance Comparison Of A Roundabout Versus Two-Way Stop Controlled (Twsc) Intersections, Deogratias Eustace Jun 2015

Performance Comparison Of A Roundabout Versus Two-Way Stop Controlled (Twsc) Intersections, Deogratias Eustace

Deogratias Eustace

The superior safety record of modern roundabouts is well known in Western Europe, Australia and in most British-influenced countries around the world. The experience from a single modern roundabout installed in the City of Manhattan, Kansas, some three years ago, also shares the same experience. A major study of the performance of Manhattan, Kansas, modern roundabout was conducted at Kansas State University (KSU) and was co-sponsored by Mac-Blackwell National Rural Transportation Study Center, Kansas State University, and the City of Manhattan. The study examined three intersections, one modern roundabout and two Two-Way Stop Controlled (TWSC) intersections with similar traffic conditions. …


Identification Of Risk Factors Associated With Motorcycle-Related Fatalities In Ohio, Deogratias Eustace, Vamsi Krishna Indupuru, Peter W. Hovey Jun 2015

Identification Of Risk Factors Associated With Motorcycle-Related Fatalities In Ohio, Deogratias Eustace, Vamsi Krishna Indupuru, Peter W. Hovey

Out of the 7,138,476 motorcycles operating on U.S. roads, 346,925 were registered in the state of Ohio in the year 2007. Although motorcycles represent only 2.8% of all registered vehicles in the state of Ohio, motorcycling accounts for more than 13% of Ohio highway traffic fatalities. Since 2005, Ohio has had a distressing distinction of being among the fifteen states that have sustained more than half of all motorcycle fatalities recorded in the USA (NHTSA 2007; NHTSA 2008a). For the past ten years, the overall motorcycle crash fatalities have been increasing while the motor vehicle occupant crash fatalities have been …


A Simplified Method For Analyzing Factors Contributing To Motorcyclists’ Fatal Injuries In Ohio, Deogratias Eustace, Vamsi Krishna Indupuru Jun 2015

A Simplified Method For Analyzing Factors Contributing To Motorcyclists’ Fatal Injuries In Ohio, Deogratias Eustace, Vamsi Krishna Indupuru

Deogratias Eustace

The aim of this paper was to analyze traffic crash data by using a simplified method in determining significant factors that increase the risk of a motorcyclist being fatally injured once involved in a motorcycle crash in Ohio. The concept of overrepresentation, which is similar to relative risk, was used in identifying significant variables associated with the elevated risk of a motorcycle crash resulting into a fatality. The overrepresentation factor (ORF) was calculated for each variable of interest. The ORF offers a simple but powerful procedure of determining whether a certain factor significantly occurs more or less frequently in one …
