View AllNorth Dakota remains one of the few states where a graduated policy for teen licensing has not been adopted and only one of two states where 14-year-olds can drive independently, despite the higher risk of teens being involved in crashes (NHTSA 2007, McCartt et al. 2003). A survey of 288 parents of teens... An integrated mobile testing study that utilized a large truck equipped with various testing equipment was conducted on Interstate I-70 in Colorado. The field study integrated wind measurement, vehicle dynamic monitoring and geospatial multimedia technology on a real-time and synchronized basis. Essential... Recent design requirements for traffic signal and sign structures incorporated fatigue load criteria related to wind that are producing significant increases in size and cost. The Fourth Edition of the AASHTO Luminaire and Traffic Signal Specification (2002 with interims) specification is a significant... This research study examined the effectiveness of the fiber reinforced polymer (FRP) spikes in repairing naturally damaged and deteriorated railroad bridge chords. Past research has shown that this process can be quite effective in improving the effective stiffness of railroad chord members that were... Rural American typically need to travel longer distances than their urban counterparts. They also tend to have lower incomes and have few travel options other than personal automobiles. As a result, rural residents spend a greater percentage of their income on motor fuel than urban dwellers. Many Native... Understanding the attitudes and perceptions of a community's members towards public transportation is valuable when designing and delivering service. In this paper, the design and descriptive statistics for the first two waves of a longitudinal study of students enrolled at North Dakota State University... A survey of teen parents was conducted at driver licensing sites across the North Dakota to ascertain perceptions and opinions regarding the current teen licensing process. A majority of the 288 parent respondents support increasing the teen permit age from the current 14 years. Many also believe that... This research provides some demographic and geographic information, but does not address highway capacity needs, right of way needs, restricted speed policy, processes for determining future access, evaluation of current access right of way needs for future frontage roads, and bypass opportunities in... This study provides an overview of alternative fuel use and potential in the Mountain Plains Region (MPR) as well as a benefit/cost analysis of switching from traditional to alternative fuels (such as ethanol and biodiesel) for a specific university in the region. The study analyzes users that would... Traffic safety is a widespread social concern. Tackling the problem requires understanding the people who are driving. This includes information about driver behavior, but also about perceptions these drivers hold regarding their driving. North Dakota crash data points at a specific group of drivers... |
