Intelligent transport systems — Co-operative ITS — Local dynamic map

This document:

—    describes the functionality of a “Local Dynamic Map” (LDM) in the context of the “Bounded Secured Managed Domain” (BSMD);

—    specifies:

—    general characteristics of LDM Data Objects (LDM-DOs) that may be stored in an LDM, i.e. information on real objects such as vehicles, road works sections, slow traffic sections, special weather condition sections, etc. which are as a minimum requirement location-referenced and time-referenced;

—    service access point functions providing interfaces in an ITS station (ITS-S) to access an LDM for:

—    secure add, update and delete access for ITS-S application processes;

—    secure read access (query) for ITS-S application processes;

—    secure notifications (upon subscription) to ITS-S application processes;

—    management access:

—    secure registration, de-registration and revocation of ITS-S application processes at LDM;

—    secure subscription and cancellation of subscriptions of ITS-S application processes;

—    procedures in an LDM considering:

—    means to maintain the content and integrity of the data store;

—    mechanisms supporting several LDMs in a single ITS station unit.
