implementation of an ITS station in a central ITS subsystem
a CALM station acting as a source node, also referred to as a service provider, distributes information to its neighbors; the receiving neighbors, also referred to as service user, optionally merge the information with their local information state and decide on a possible re-distribution of the (merged) information.
a source node defines a geographical destination area and distributes information to appropriate neighbors; receiving nodes being outside the destination area re-distribute the information to appropriate neighbors; receiving nodes being inside the destination area broadcast the information.
ITS station communication unit in which remote ITS station management is performed by a remote management server
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.
party which is responsible for receiving probe messages sent by a probe data sender
NOTE A probe data collector is responsible for probe data at any stage.
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.
table in an AME that stores management related information for resident applications
data from probe data messages which has been collated and analyzed in combination with other data
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.
