HIVAL: A SIMULATION AND DECISION SUPPORT SYSTEM FOR AHS (AUTOMATED HIGHWAY SYSTEMS) CONCEPTS ANALYSIS

In order to meet the present and future needs of Automated Highway System (AHS) concept analysis and tradeoff studies, a prototype integrated modeling, simulation, and decision support testbed, called HiVal, has been developed under the AHS Precursor Systems Analyses (PSA) Program. HiVal accommodates a range of user expertise and objectives, ranging from high-level, aggregate AHS performance metrics and tradeoffs, to low-level, detailed simulation of individual AHS subsystem elements. HiVal provides a computing environment which integrates a variety of simulations, models, and databases from both PSA activities and the broader AHS research community. More than a dozen simulations and models have been incorporated into the prototype system. HiVal uses a modular, distributed client-server computing architecture. Modern workstation technology (Unix & X-Motif, DOS/MS Windows, DCE, TCP/IP) is used throughout to support a wide variety of modeling and simulation needs, and allow for continued system growth. All of HiVal's basic interfaces, protocols, and control software uses COTS (Commercial Off The Shelf) technology. A functional prototype of HiVal has been implemented and provided to FHWA.
