U.S.-France (INRIA) Cooperative Research: Analysis of Hybrid Systems and Application to the PATH Project

点击翻译按钮获取中文摘要

This three-year award supports U.S.-France cooperative research between the PATH project of the University of California at Berkeley, led by Pravin Varaiya, and the SPECTRE project of INRIA (French National Institute for Research in Informatics and Applied Mathematics) led by Joseph Sifakis of INRIA/Rhone-Alpes. The objective of the PATH project is to design automated highway systems so that capacity and safety of surface transportation are increased substantially. This project is part of the Federal Highway Authority's Intelligent Transportation Systems Program. SPECTRE's objectives are to (1) design and develop programming languages for concurrent and real-time systems; (2) define and study models and specification languages; and (3) design and implement validation techniques adapted to specification languages. The objective of the proposed collaboration is to apply techniques in hybrid systems theory and verification tools to PATH's design of automated highway systems. The U.S. groups brings to this collaboration their expertise in theory for hybrid control and verification and a test environment, the automated highway systems project. This is complemented by the control and verification tools developed by French group at INRIA. The project is expected to advance our understanding of hybrid systems theory and verification tools.
