The MOVES model was developed by the U.S. Environmental Protection Agency (U.S. EPA) to estimate emissions from on-road mobile sources and non-road sources in the United States. Coupling high-resolution on-road vehicle activity data with appropriate MOVES emission rates further advances research efforts designed to assess the environmental impacts of transportation design and operation strategies. However, the complicated MOVES interface and slow performance makes it difficult to assess large, regional-scale transportation networks and to undertake analyses of large-scale systems that are dynamic in nature. The MOVES-Matrix system develops an initial large matrix of MOVES outputs by running MOVES 146,853 times on the PACE high performance computing cluster, generating more than 90 billion emission rates to populate the matrix for a single modeling area (one fuel regime and one inspection and maintenance program). A total of 117 such large matrices are needed for the entire United States. The MOVES-Matrix system can be used to conduct the emissions modeling 200-times faster than using MOVES and generates the exact energy use and emission results as the MOVES model. The resulting matrix allows users to link emission rates to big data projects and to evaluate changes in emissions for dynamic transportation systems in near-real-time.
