BS EN ISO 18750:2018

This standard BS EN ISO 18750:2018 Intelligent transport systems. Co-operative ITS. Local dynamic map is classified in these ICS categories:

• 03.220.20 Road transport
• 35.240.60 IT applications in transport

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.
