probe data reporting management commands

commands sent within probe vehicle systems to manage the content and transmission of probe messages.
NOTE: Examples include: (a) selectively enable or disable various levels of probe data reporting, (b) selectively enable or disable reporting of particular types of probe data, (c) adjust the criteria for probe data reporting for specific probe data elements (for example “do not report a…

commands sent within probe vehicle systems to manage the content and transmission of probe messages.
NOTE: Examples include: (a) selectively enable or disable various levels of probe data reporting, (b) selectively enable or disable reporting of particular types of probe data, (c) adjust the criteria for probe data reporting for specific probe data elements (for example “do not report a smaller than ±3 degree difference in air temperature), or (d) adjust the criteria for probe data reporting for specific probe data elements based on the delta value. These PDRM instructions can be structured with time and/or geographic information to define a context which the instructions are valid.

probe data reporting management messages

probe header

set of data required in order to effect a transmission
NOTE: It is (the information) processed at the communication layer, such as a unique communication ID, and includes information on the transmitting/original entity. Personal data may be included depending on the communication medium used.

probe message

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…

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.

probe package

set of data blocks transmitted from vehicles to probe data collectors
NOTE: A probe package includes/constitutes a probe payload and a probe header.

set of data blocks transmitted from vehicles to probe data collectors
NOTE: A probe package includes/constitutes a probe payload and a probe header.

probe payload

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.

probe processing

land-side activity which receives collected probe data from probe collection and processes it
NOTE: Probe processing does not receive any information from probe collection that identifies the vehicle or driver.

system that comprises (1) vehicles which collect and transmit probe data and (2) land-based centres
which do probe processing
NOTE 1 to entry: Probe processing builds an accurate understanding of the overall roadway and driving
environment by fusing and analysing probe data sent from multiple vehicles and data from other data sources.
NOTE 2 to entry: This processed probe data can then be delivered back to vehicles to help them and their drivers
perform better, to public authorities to help them manage the transportation system, and to other users for a
variety of purposes.
