E-raamat: Intelligent Transportation Systems: Dependable Vehicular Communications for Improved Road Safety

This book presents cutting-edge work onthe most challenging research issues concerning intelligent transportationsystems (ITS), introducing selected, highly relevant advanced research onscheduling and real-time communication for vehicular networks, as well as faulttolerance, test beds and simulations for ITS. The authors define newarchitectures that support cooperative sensing in ITS and offer guidance forthe development of a reference end-to-end implementation. The presented resultsallow advanced traffic and travel management strategies to be formulated on thebasis of reliable and real-time input data. The effectiveness of these newstrategies, together with the proposed systems, is assessed in field trials andvia simulations.The chapters in this book detail newresearch findings, algorithms, protocols, and the development of animplementation platform for ITS that merges and integrates heterogeneous datasources into a common system. In addition, they provide a set of

advanced toolsfor the control, monitoring, simulation, and prediction of traffic that resultin safer, more sustainable, and less congested roads.Work undertaken within the framework of theFP7 project ICSI (Intelligent Cooperative Sensing for Improved trafficefficiency) is also included in the research activities addressed.
