LACASA: A Layered Architecture for Cooperative Active Safety Applications

The future of Intelligent Transportation Systems is intertwined with the development, implementation, and penetration of distributed sensing and communications networks. We propose a general, cooperative, holistic active safety framework, LACASA, that can make immediate and significant impacts on safety as part of a stand-alone driver assistance systems in vehicles. The cooperative modularity of the framework is such that as the market penetration of V2V and V2I sensing and networking improves, the safety benefits of the system grow tangibly as well. The LACASA framework draws on recent results into the predictability and responsiveness of drivers in various situations, as well as improvements in machine vision and artificial intelligence.
