Description / Abstract: ISO 22837:2009 relates to vehicle probe data for wide are communications. It specifies the following. Reference architecture for probe vehicle systems and probe data, which provides a general structure for probe vehicle systems within which a wide range of actual probe vehicle systems can be built whose physical characteristics may differ (e.g., in their choice of communications medium). The reference architecture is used to: clarify the major building blocks and logical interconnections of probe vehicle systems for which this standard will be used; categorize probe data in accordance with the information model described below. Basic data framework for probe data elements and probe data, which defines probe data elements and probe messages, and specifically provides: rules for mapping information models (as defined in ISO 14817) of probe data to probe data elements/messages. The information models show the logical structure of entities and concepts involved in probe data; the required characteristics of probe data elements and probe data messages; the notation for probe data elements/messages (in XML); rules for using core data elements and basic data elements (see below), and extensions of data elements in each application domain. Core data element definitions, which are basic descriptive elements intended to appear in every probe message, i.e. the location and the time at which the probe data was sensed. Initial set of probe data elements, which are commonly used in typical probe data enabled application domains, such as traffic, weather, and safety. Example probe messages, which define how probe data elements are combined to convey information to probe processing centres.
