| 摘要： | The wide variety of remote sensors used in Intelligent Transportation Systems (ITS) applications (loops, probe vehicles, radar, cameras, etc.) has created a need for general methods by which data can be shared among agencies and users who own disparate computer systems. In this paper a methodology is presented that demonstrates that it is possible to create, encode, and decode a self-describing data (SDD) stream using existing data description language standards, parsers to enforce language compliance, a simple content language that flows out of the data description language, and architecture neutral encoders and decoders based on Abstract Syntax Notation One (ASN.1). Further, it documents a reference implementation of an SDD receiver. |
