The effective analysis of transportation operations strategies for planning and investment decisions requires an accurate and complete understanding of transportation system performance obtained by integrating multiple sources of transportation data from multiple stakeholders. This report examines the state of the practice in data sharing and integration, specifically (1) current data sharing and integration practices among State and local agencies, (2) example data environments, (3) technical integration formats, and (4) business rules for integration and sharing.
The review was conducted at the outset of a Federal Highway Administration project to develop a prototype framework for sharing planning and operations data between State and local transportation agencies from multiple sources within a region. The results of the review were used to inform the development of the framework. Transportation operators, planners, and data professionals can use this report to enhance their data sharing and integration efforts by building on the experiences and effective practices of other agencies that are documented in this report.

16. Abstract The purpose of this state-of-the-practice review was to lay both technical and institutional foundation for all aspects of the development of the Virtual Data Access Framework. The review focused on current data sharing and integration practices among State and local agencies, example data environments, technical integration formats, and business rules for integration and sharing. State, local, and regional transportation operators, planners, and data professionals can use this report to enhance their data sharing and integration efforts by building on the experiences and effective practices of other agencies documented in this report. |
