Motor vehicle drivers’ injuries in train–motor vehicle crashes

Accident Analysis & Prevention, 2015
The objectives of this research were to: (1) identify a more suitable model for modeling injury severity of motor vehicle drivers involved in train-motor vehicle crashes at highway-rail grade crossings from among three commonly used injury severity models and (2) to investigate factors associated with injury severity levels of motor vehicle drivers ...

Motor Vehicles, Hypoglycemia, and Diabetic Drivers

Diabetes Care, 1989
Individuals with diabetes are increasingly persuing employment in fields previously restricted as a result of the development of chronic complications. Improved glycemic control resulting from use of sophisticated insulin delivery and monitoring systems has also led to the recognition of recurrent hypoglycemia as a potential major clinical and ...
