Intelligent transport systems - Co-operative ITS - Local dynamic map (ISO 18750:2018)
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.
