Abstract:

As an energy-efficient transportation mode, railways play a vital role in U.S. freight transportation. During any natural or man-made disasters, it is essential to keep the freight flow by efficiently re-routing the disrupted traffic. This project develops a model for routing the trains to minimize the total travel time for the whole network and determines how significant disruptions to railway infrastructure impact regional and inter-regional freight movements. The routing problem is formulated as a minimum-cost network flow problem that has a nonlinear objective function of minimizing the total travel time on all links and considers Origin-Destination specific demand. To make the model computationally tractable, the nonlinear travel time function at each link is approximated with a piece-wise linear function so that the whole model can be directly solved by ILOG CPLEX 9.0. The criticality of a railway link is evaluated by the increased delay when the link is disrupted. A case study is conducted for the railway network in the State of Mississippi. The map showing criticalities of all links in the study area is provided. In addition, this article discusses about the literature and data availability of other two surface transportation modes – highway and waterway.
