Achieving and maintaining public transportation rolling stocks in a state of good repair is very crucial to providing safe and reliable services to riders. Transit agencies that seek federal grants must also keep their transit assets in a state of good repair. Therefore, transit agencies in small urban...

This study was conducted to provide the Oklahoma Transit Association and state policy makers with information that will allow them to plan for mobility challenges and address coming greater mobility needs stemming from population growth and changes in the state’s demographics. In this study, we constructed...

This report is the response to the North Dakota Legislature's request for a study of the transportation infrastructure needs of all county and township roads in the state. In this report, infrastructure needs are estimated using the most current production forecasts, traffic estimates, and roadway inventory...

This study identified and analyzed existing transit and other passenger mobility options in North Dakota. Information about population growth trends and demographics across the state are described and used to identify areas with the greatest needs for mobility services. Transit service levels across...

In Wyoming, most county paved roads were built decades ago without following minimum design standards. However, the recent increase in industrial/mineral activities in the state requires developing an efficient pavement management system (PMS) for local paved roads. The new PMS which is currently being...

This research seeks to investigate crash severity predicting models and contributing factor explorations through the application of data mining models. There are 21 variables found to be associated with commercial truck injury severities. The importance analysis indicates the variable relative important...

In order to predict the functionality of transportation networks following a seismic event, performance of embankments under real ground motions needs to be well understood. Understanding of such performance can be realized using experimental testing or finite element analysis. This study aims to add...

Discoveries of shale gas reserves along with the development of horizontal drilling and hydraulic fracturing techniques, as well as the initiative to move the United States toward greater energy independence led to the most recent oil boom in western North Dakota (U.S. Congress 2007). Overall, the boom...

The highway-rail crossing accident has been long recognized as a priority safety concern for worldwide rail industries and researchers because traffic crashes at highway-rail crossings are often catastrophic with serious consequences, which include fatalities, injuries, extensive property damage, and...

This report the response to the North Dakota Legislature's request for a study of the transportation infrastructure needs of all county and township roads in the state. In this report, infrastructure needs are estimated using the most current production forecasts, traffic estimates, and roadway inventory...
