RailNTA is a project led by CTSM in collaboration with the Federal Railroad Administration (FRA). The objectives of this project are to (1) implement and use a network analysis Python computer code, designed to quantifying the topological connectedness efficiency of freight railroad networks for resilience studies; (2) design the architecture of a Tool for Rail Network Topological Analysis and Throughput Assessment and; (3) use aggregate network to illustrate the methodology and the tools, and offer a proof of concept in coordination with FRA and industry partners.
