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.
