Each year there are more than 16,000 motor vehicle crashes (MVCs) on North Dakota roadways, resulting in more than 2,900 injuries and 107 fatalities. Understanding the economic impacts of these MVCs is important in discerning impacts of road investments, behaviors, and policy changes that affect public...
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...
The North Dakota legislature recently passed a law to exempt the state's agricultural truck fleet from a requirement for rear-guard equipment as federally mandated large trucks. This analysis presents the public safety benefit-cost assessment of the device in terms of crash injury severity associated...
Animal-vehicle crashes are a concern for many areas of the country but are a particular concern for rural areas such as Wyoming. While there is considerable literature available on the effectiveness of various animal-vehicle countermeasures, such as fencing and signing, there is currently little quantifiable...
A study of collisions occurring at intersections along State routes in Utah was conducted. The number of crashes, the crash severity score and, for selected locations, the crash rate were determined and "ranked" for intersections within the Utah Department of Transportation's Region 1, Region 2, Region...
The movement of freight within the state of Wyoming is very critical to Wyoming's economy as well as the national economy. Wyoming's transportation system provides a vital link for the movement of commodities across the United States, in addition to providing access to the mineral, industrial, and agricultural...
This project investigates alternate forms of dissemination for the accident information. Costs, capabilities, and compatibility are reviewed for integration of the accident database with a GIS format to allow a graphical and spatial interface. The issues being addressed by this research focus on information...
Many rural governments do not have an effective safety improvement program for their roads, yet crash rates are significantly higher on rural roads than on urban, state, and federal roads. Smaller agencies seldom have the financial resources or expertise to provide comprehensive roadway safety improvement...
North Dakota has more than 102,000 miles of rural roads. Approximately half of these roads are paved and the rest are gravel or dirt. Due to limitations in funding and shifts in traffic patterns, counties and townships are forced to make difficult decisions regarding the maintenance of their roads. Some...
The primary objective of this research was to establish statistically valid mathematical models that can explain the variations in accidents as a function of geometric variables. Engineers and planners will be able to use these models to examine the sensitivity of accident rates to any of the independent...
