A wide variety of remote sensors used in Intelligent Transportation Systems (ITS) applications (loops, probe vehicles, radar, cameras) 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, we present a methodology that demonstrates that it is possible to create, encode, and decode a self-describing data stream using the following:
1. existing data description language standards
2. parsers to enforce language compliance
3. a simple content language that flows out of the data description language
4. architecture neutral encoders and decoders based on ASN.1.
