 | Archived Data Management System – Data Model |
| This software tool defines data requirements for an Archived Data Management System (ADMS), as defined in the National ITS Architecture. Definition of these requirements has been performed in order to more clearly define the key actors – i.e., entities that interact with the ADMS – and how these key actors would use the system. The ADMS Data Model includes a class diagram and sequence diagram for each of the three types of data interfaces: management of archive configuration, retrieval of data, and submittal of data. The ADMS Data Model also links to a white paper on the Rational Unified Process for software development, as well as allows the user to view ADMS system diagrams at two levels of analysis: the Use Case View and the Logical View. Finally, the tool links to a report upon which the information in the ADMS Data Model is based.

| National Evaluation of the TMC Applications of Archived Data Operational Test – ADMS Virginia (2005) |
| This report documents the findings of an operational test of the use of archived data to improve decision-making in the operation and management of a transportation network. The test took place in the Northern Virginia and Hampton Roads, Virginia metropolitan areas. The specific archived data management system (ADMS) evaluated in the test was the ADMS Virginia system developed by the Smart Travel Lab at the University of Virginia. The evaluation found that the ADMS Virginia system works well in the transportation operations and management environment. ADMS Virginia was found to overcome significant data quality challenges, experience a significant growth in usefulness when incorporating event data, but was hampered by the limited data surveillance available about the transportation network.

| Lessons Learned: Monitoring Highway Congestion and Reliability Using Archived Traffic Detector Data (2004) |
| This report summarizes lessons learned from the Mobility Monitoring Program regarding the use of archived traffic detector data for monitoring highway performance. The Mobility Monitoring Program started in 2000 with archived freeway detector data from 10 cities. By 2004, the program had grown to nearly 30 cities, covering about 3,000 miles of freeway. The lessons learned are centered in three general areas: analytical methods, data quality, and institutional issues. Cost: Free To Access This Resource: Access the following website addresses:

| Traffic Data Quality Measurement: Final Report (2004) |
| This report presents a framework calculating data quality metrics for different applications. The framework is based on six recommended fundamental measures of traffic data quality: accuracy, completeness, validity, timeliness, coverage and accessibility. The report also presents guidelines and standards for calculating data quality measures, estimates the level-of-effort required of an agency to bring its data up to each standard, and presents recommended guidelines for data sharing agreements. Three case studies show how the traffic data quality metrics were applied to real-world data.

| Traffic Data Quality Workshop Proceedings and Action Plan (2003) |
| This document presents a series of recommended steps to be taken by the U.S. DOT, stakeholder organizations, and state departments of transportation to improve the quality of traffic data. These recommendations were developed following development of a series of three white papers that explore issues and current practices for ensuring data quality, and hosting of two regional workshops in Columbus, Ohio, and Salt Lake City, Utah, on March 11, 2003, and March 13, 2003, respectively. This document provides proceedings of the workshops, as well as identifies 10 priority action items to be taken to improve traffic data quality nationwide.
