Abstract: The Mobility Systems Branch (MSB) has a long history of providing Tactical Decision Aids (TDA) for military planning systems and ground movement algorithms for Modeling and Simulation (M&S). These TDA and M&S algorithms are based on the NATO Reference Mobility Model (NRMM), which is an Army Model and Simulation Office (AMSO) standard for ground vehicle movement. There is currently a need to characterize vehicle pass rates in M&S as well as for planning and operations in the Army and Department of Defense (DoD). In particular, the theater-level Joint Warfare Simulations (JW ARS) model has a requirement to represent ground movement in terms of a vehicular pass rate through an area. These pass rates are assigned to edges which are connected by nodes to form a movement network. Each edge may be required to represent several roads as a result of the large terrain areas that a theater-level model must accommodate. The MSB was tasked to provide vehicle pass rates and software to aggregate the roads provided in the Compact Terrain Data Base (CTDB) into a simpler network. The purpose of this report was to present the methodology and results of a process which categorizes the transportation network and the derivation of the associated pass rates for convoys of vehicles. The first part of the report describes the process of deriving the pass rates and average speeds for vehicle convoys. Then the methodology for categorizing and aggregating the transportation network is presented. This software has been developed to generate the movement network for JWARS. Based on the results of this investigation, the following conclusions can be drawn: (A.) An overall methodology to represent ground vehicle movement across a theater has been developed based on the NRMM. (B.) A network aggregation methodology was developed to simplify representation of movement and retain capacity characteristics within a theater of operations. (C.) Estimates of pass rates were generated based on readily available data for a synthetic natural environment.
