Abstract: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 report, 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 decodes based on ASN.1.
