Safety Region Based Active Safety Methods

The safety region based active safety methods are discussed in this section. A safety region analysis model is proposed based on formalized description of some basic definitions like safety region estimation, multi-domain division and etc. Relative relationship between safety region boundary and system operating point can provide quantitative safety margin and optimal control information under various conditions. Furthermore, safety region based accident-causing model is also researched. In addition, in order to prevent future accidents, the relationship of the causation found out in each part of procedure is established by disclosing the interaction of the components in the system. Real rail transportation cases are studied to verify the performance of the proposed theory.
