- generating different traffic factors (seasonal, growth, day of week, hourly, K-factor, directional, classification, etc.) that are used to estimate the above statistics when/where not enough data is available

Some initial and possibly incomplete or outdated in some places documentation for the above processes already exists and will be shared with the Contractor.

To fully understand the processes used for the tasks above, the Contractor will shadow the Senior Oracle Database Architect/Engineer, observe his work, and take notes.

The Contractor will be tasked with making sure that documentation is complete, easy to understand, and up-to-date by working with both the Senior Database Architect/Engineer and the and users of these data sets, such as Data Scientists and Architect/Engineers and Data Analysts.

For replication, the Contractor will run the Oracle scripts used to produce the above measures in a test environment and validate their results against the results from the production environment produced by the Senior Oracle Database Architect/Engineer.

The Contractor will need to understand, document, and replicate the general procedures as well as the special/edge cases, where a case-by-case decision or human decision may be needed.

The possibility of creating parallel non-Oracle SQL code that connects to the Oracle database, processes the data outside Oracle, and writes it back to the Oracle database is preferable, and will be offered to the Contractor.

Task 2:

The Contractor will perform the same tasks (understand, replicate results, produce technical documentation) for other modules of the VDOT TMS (Traffic Management System), the most important ones being Payment, and Link Management.

For this task, the Contractor will work with the Senior Oracle Database Architect/Engineer and the Traffic Data Analysts, Traffic Monitoring Systems Engineers, and Engineering Techs who use these modules.
