EN 16803-1 addresses the final stage of the performance management approach, i.e. the assessment of the whole Road ITS system performance equipped with a givenPositioning System, using theSensitivity analysismethod. EN 16803-1 addresses the identification and the definition the positioning performance features and metrics required for Positioning System assessment. This document gives definitions of the various items to be considered when specifying anOperational scenarioand provides a method to compare finely two environments with respect to their effects on GNSS positioning performance. This document gives definition of the most important terms used all along the document and describes the architecture of aRoad ITS systembased on GNSS as it is intended in this standard.All current amendments available at time of purchase are included with the purchase of this document.
