The Use Of 3-D Highway Differential Geometry In Crash Prediction Modeling, Kiriakos Amiridis
The Use Of 3-D Highway Differential Geometry In Crash Prediction Modeling, Kiriakos Amiridis
Theses and Dissertations--Civil Engineering
The objective of this research is to evaluate and introduce a new methodology regarding rural highway safety. Current practices rely on crash prediction models that utilize specific explanatory variables, whereas the depository of knowledge for past research is the Highway Safety Manual (HSM). Most of the prediction models in the HSM identify the effect of individual geometric elements on crash occurrence and consider their combination in a multiplicative manner, where each effect is multiplied with others to determine their combined influence. The concepts of 3-dimesnional (3-D) representation of the roadway surface have also been explored in the past aiming to …
Effect Of Socioeconomic And Demographic Factors On Kentucky Crashes, Aaron Berry Cambron
Effect Of Socioeconomic And Demographic Factors On Kentucky Crashes, Aaron Berry Cambron
Theses and Dissertations--Civil Engineering
The goal of this research was to examine the potential predictive ability of socioeconomic and demographic data for drivers on Kentucky crash occurrence. Identifying unique background characteristics of at-fault drivers that contribute to crash rates and crash severity may lead to improved and more specific interventions to reduce the negative impacts of motor vehicle crashes. The driver-residence zip code was used as a spatial unit to connect five years of Kentucky crash data with socioeconomic factors from the U.S. Census, such as income, employment, education, age, and others, along with terrain and vehicle age. At-fault driver crash counts, normalized over …
