Abstract
Address is the information to uniquely identify objects to be communicated. It is necessary to manage address information like physical locations and IP addresses in intelligent transportation systems (ITS) communications environment. This paper proposes a new method for ITS address management using Lightweight Directory Access Protocol (LDAP) and eXtensible Markup Language (XML). In this method, LDAP is for an access protocol and an information model, and XML is for a data store format. It allows us to facilitate the access to ITS address information from various Internet applications and spread ITS information described by XML through LDAP.
