Project objective. To develop a prototype data warehouse and data mining applications, with the objective of demonstrating the value of saving traffic data and potential applications.

Project abstract. The Northern Virginia Signal System collects large quantities of traffic data. The Northern Virginia system, like others in the United States, does not archive this data for long periods of time. Therefore, valuable information is lost. This project, which is possible because of the existing data link between the signal system and the Smart Travel Laboratory, will explore various data mining opportunities available from this database.

Tasks. 1) develop a prototype data warehouse and data mining applications for evaluation by appropriate transportation operating officials. 2) prepare final report detailing project results.

Milestones. This project will be completed in July 2001.

Student involvement. Two full-effort GRAs through the project.

Budget.  $130,000

Relationship to other research projects. Closely related to Adaptive signals decision support system project described above; emphasis here is on data management.

Technology transfer. Professional publication. Transmittal to VDOT operating personnel.

Potential benefits. Enhance the usefulness of the Smart Travel Lab. Enhance the capabilities of the Signal Support System described above.
