Results for area 14.1 Vehicle communication
device within a vehicle that senses conditions inside and/or outside the vehicle or that detects actions that the driver takes
structured collation of data elements suitable to be delivered to the onboard communication device for transmission to a land-based centre
NOTE It is emphasized that a probe message should not contain any information that identifies the particular vehicle from which it originated or any of the vehicle’s occupants, directly or indirectly. In delivering a probe message to be transmitted by the onboard communication device, the onboard data collection system will request that the message be packaged and transmitted without any vehicle or occupant identifying information.
vehicle sensor information formatted as probe data elements and/or probe messages that is processed, formatted, and transmitted to a land-based centre for processing to create a good understanding of the driving environment
event based probe data includes event based probe data elements and event based probe messages
NOTE 1 to entry An algorithm in the vehicle constantly processes sensor readings and determines if a specific event has occurred. An event based probe data message is sent only when a specific incident or event occurs. It is not transmitted in a periodic manner. The transmission of an event based probe message itself indicates that an event has occurred An event based probe message is defined as a probe message that is not triggered by a periodic occurring condition (i.e. time or distance). It is typically triggered after a defined event has occurred or an event has been detected by the vehicle on board system (i.e. low visibility or traffic jam entry). An event may be defined as simple as a change in status of a standard probe data element (i.e. fog light switching state) or can refer to a complex incident detected by a detection algorithm (i.e. traffic jam entry).
an event based probe data element is an item of data included in an event based probe message, typically describing the event that has triggered the transmission of the message
set of data blocks transmitted from vehicles to probe data collectors
NOTE A probe package includes/constitutes a probe payload and a probe header.
data item included in a probe message
set of data transmitted at the application layer from vehicles to probe data collectors
NOTE A probe payload includes/constitutes probe messages and authentication data. A probe message does not include any personal data, however, personal data may be included in a probe payload.
person who drives the vehicle equipped with probe in-vehicle system
probe data sender from a vehicle to a probe data collector in a probe vehicle system
