Since the mid-1990s, the U.S. Department of Transportation (U.S. DOT) Federal Railroad Administration (FRA) has sponsored a research program on alternative detection technologies for railroad right-of-way (ROW) and highway-rail grade crossing applications. In support of this effort, the John A. Volpe National Transportation Systems Center (Volpe Center) of the U.S. DOT Research and Innovative T...

In this paper, some practical solid transportation models are formulated considering per trip capacity of each type of conveyances with crisp and rough unit transportation costs. This is applicable for the system in which full vehicles, e.g. trucks, rail coaches are to be booked for transportation of products so that transportation cost is determined on the full of the conveyances. The models w...

Safety is a high priority for any rail system, and there are several safety concerns associated with operating passenger and freight trains on shared-use rail corridors. Adjacent track accident (ATA) is one of the most important concerns. ATA refers to train accident scenarios where a derailed equipment intrudes adjacent tracks, causing operation disturbance and potential subsequent train colli...
