Self-Describing Data Transfer Methodology for ITS Applications

摘要

The wide variety of remote sensors used in Intelligent Transportation Systems211u001e(ITS) applications (loops, probe vehicles, radar, cameras, etc.) has created a 211u001eneed for general methods by which data can be shared among agencies and users who 211u001eown disparate computer systems. In this paper, we present a methodology that 211u001edemonstrates that it is possible to create, encode, and decode a self-describing 211u001edata stream using the following: 1. existing data description language standards, 211u001e2. parsers to enforce language compliance, 3. a simple content language that 211u001eflows out of the data description language, and 4. architecture neutral encoders 211u001eand decoders based on ASN.1.
