UNE-EN ISO 18750:2026

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.
