Intelligent transport systems - 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 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.
