| 摘要： | In order to meet the present and future needs of Automated Highway Systems (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 Analysis (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 the Federal Highway Transportation Administration (FHWA). |
