Crash Frequency Analysis Of Left-Side Merging And Diverging Areas On Urban Freeway Segments: A Case Study Of I-75 Through Downtown Dayton, Ohio, Deogratias Eustace, Aline Aylo, Worku Y. Mergia
Crash Frequency Analysis Of Left-Side Merging And Diverging Areas On Urban Freeway Segments: A Case Study Of I-75 Through Downtown Dayton, Ohio, Deogratias Eustace, Aline Aylo, Worku Y. Mergia
Civil and Environmental Engineering and Engineering Mechanics Faculty Publications
This paper analyzes the effect of left- and right-side merging and diverging areas and other variables such as light condition, roadway pavement condition, drivers’ age and presence of construction work zones on the occurrence frequency of crashes. A 6.5-mile (10.5-km) section of I-75 that passes through downtown Dayton, Ohio was considered. The area of interest has a high traffic volume and consists of different geometric design challenges including closely spaced merging and diverging ramps. A four-year record of crash data (2005–2008) and a statistical modeling technique that assumes a negative binomial distribution on generalized linear models (GLMs) were used to …

Identifying factors that affect crash injury severity and understanding how these factors affect injury severity is critical in planning and implementing highway safety improvement programs. Factors such as driver-related, traffic-related, environment-related and geometric design-related were considered when developing statistical models to predict the effects of these factors on the severity of injuries sustained from motor vehicle crashes at merging and diverging locations. Police-reported crash data at selected freeway merging and diverging areas in the state of Ohio were used for the development of the models. A generalized ordinal logit model also known as partial proportional odds model was applied to …
Review: 'American Cars, 1973‐1980: Every Model, Year By Year', Jack O'Gorman
Review: 'American Cars, 1973‐1980: Every Model, Year By Year', Jack O'Gorman
Roesch Library Faculty Publications
This title, part of an ongoing series, chronicles American cars made between 1973 and 1980. Entries include background on the nameplate, models available, cost, and measurements of the vehicle. Photos of the cars are shown by manufacturer and year, and the advertising slogans used to sell the cars are a nice touch to open each entry.Appendixes include minor makes and "replicars" (a copy of a vintage or classic automobile), option groups and packages, tire sizes, identification and recalls, and manufacturer logos. This work for American car enthusiasts may be better suited in the circulating collection than the reference collection and …
A Simplified Method For Analyzing Factors Contributing To Motorcyclists’ Fatal Injuries In Ohio, Deogratias Eustace, Vamsi Krishna Indupuru
A Simplified Method For Analyzing Factors Contributing To Motorcyclists’ Fatal Injuries In Ohio, Deogratias Eustace, Vamsi Krishna Indupuru

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 …
Seat Belt Use Compliance In Kansas, Deogratias Eustace, Teresa M. C. Bartel
Seat Belt Use Compliance In Kansas, Deogratias Eustace, Teresa M. C. Bartel
Civil and Environmental Engineering and Engineering Mechanics Faculty Publications
Passenger vehicle occupant restraints are regarded as the easiest and the most effective way of reducing the number of highway fatalities. Strong vehicle occupant protection enforcement laws are regarded as the most effective way to increase seat belt use. The increase in restraint use in the United States and other countries has been largely attributed to mandatory seat belt use legislation. Many fatalities and injuries in motor vehicle crashes could be avoided if more passengers used their seat belts. Studies have shown that primary laws have been more effective in seat belt use compliance than secondary laws. Also, legislation has …
