Intelligent transport systems — Local dynamic map

Apstrakt

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 can be stored in an LDM, i.e. information on real objects such as vehicles, road works sections, slow traffic sections, special weather condition sections, 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 for maintaining the content and integrity of the data store;
—    mechanisms supporting several LDMs in a single ITS station unit.
