New Model for Highway-Rail Grade Crossing Accident Prediction and Severity

The U.S. Department of Transportation Accident Prediction and Severity (APS) model has been used by Federal, State, and local authorities to assess accident risk at highway-rail grade crossings since the late 1980s. The Federal Railroad Administration funded research for the development of a new...

Railroad Software-Defined Radio

Transportation Technology Center, Inc. assessed the potential use of a software-defined radio to meet the current and future wireless communication needs of the U.S. railroad industry. FRA funded this project due to the high level of complexity involved in developing requirements and a preferred...
