智能交通系统-本地动态地图

[中文适用范围]： 描述了'本地动态地图'(LDM)在有界安全管理区域(BSMD)上下文中的功能；指定了LDM数据对象(LDM-DO)的一般特征，这些对象可以存储在LDM中，例如关于车辆、道路施工部分、缓慢交通部分、特殊天气条件部分等的实时信息，所有这些都是最低要求的位置引用和时间引用；服务访问点功能为ITS站(ITS-S)提供接口以访问LDM进行安全添加、更新和删除访问以及安全读取访问（查询）、安全通知订阅以及管理访问 [外文原描述]： 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.
