The paper presents an analytic approach to generate the market packages for the operation via the Intelligent Transportation System (ITS) architecture. This analytic approach uses the concepts of the "Use Case Diagram" and "Sequence Diagram" defined by the Unified Modeling Language (UML). By following the steps, we take Taiwan's Public Bus Service as an example and generate the market package effectually, Public Bus Monitoring and Public Bus Scheduling and Dispatching, which is corresponding to the real world situation. We also point out the academic models in market packages that could be the patent products. Consequently, driving the establishment of ITS market package not only conduces to ITS development but also promotes the Knowledge Economic in our society.
