Urban freight planning is more complex than urban passenger transport in many respects. The complexity of the planning process arises from the fact that (i) movement of freight in an urban area is part of a logistics chain for diverse goods moved from points of production via warehouses and distribution...
This study sought to determine current knowledge-levels of health care providers regarding child passenger safety issues and frequency of counseling on this topic. In addition, this study explored the differences in child restraint knowledge levels and current counseling frequency between rural and urban...
Motorcycle use brings increased risk to the operator simply by the nature of the vehicle. When a crash occurs, the threat of injury or death is magnified by physical exposure compared to that of other vehicle occupants. Detection and gap/speed judgments by other motorists present additional hazards to...
The purpose of this study is to provide information about railroad fuel efficiency that may be useful in evaluating transportation energy policies and assessing the sustainability of potential projects. The specific objectives are to (1) develop railroad energy efficiency models that describe differences...
This study analyzes economies of scale and density as a rationale for subsidizing transit agencies in small urban areas. A long-run cost model is estimated using data from 2006 to 2009 for 168 transit agencies that directly operated fixed-route bus service in small urban areas. Using vehicle revenue...
The built environment consists of everything humanly made, arranged, or maintained (Bartuska and Young 1994). In relation to travel behavior, there has been a focus on improving our understanding of how the built environment influences one's travel mode choice. Planners need evidence showing how land...
In an attempt to predict these crashes, North Dakota driver licensing data and crash data were used to develop a sample of 20,392 teen drivers age 14 to 17. Within the first year after being licensed, these drivers sustained 317 crashes that resulted in an injury or death. The resulting logistic regression...
North Dakota consistently experiences a relatively high level of crashes and injuries on rural roads, considering lane miles and vehicle miles traveled. Approximately 55% of the state's travel, in vehicle-miles, takes place on rural roads. North Dakota fatal crash reports from 2003 to 2007 show that...
Occupant protection is one of the easiest and most inexpensive ways to protect yourself when riding in a motor vehicle. Yet many North Dakota youth, especially rural youth, fail to wear their seat belts, even with a primary seat belt law for children under the age of 18 in the state of North Dakota....
Seating children in the rear of vehicles has been shown to decrease the odds of being fatally injured in a motor vehicle crash by 36% to 40%. Although rear seating is safer, rates of children being front-seated remain high, especially for older children. Few states have enacted legislation regarding...
