1	USDOT Perspective on Data Collection, Aggregation and Distribution Transportation Research Board Annual Conference Workshop on Pervasive Data Date: Sunday, Jan. 23, 2011
2	Presentation Outline
3	Networked Environment
4	The U.S. DOTMobility Program
5	Real-Time Data Capture and Management Vision Active acquisition and systematic provision of integrated, multi-source data to enhance current operational practices and transform future surface transportation systems management Objectives Enable systematic data capture from connected vehicles (automobiles, transit, trucks), mobile devices for passengers, and infrastructure Develop data environments that enable integration of data from multiple sources for use in transportation management and performance measurement Reduce costs of data management and eliminate technical and institutional barriers to the capture, management, and sharing of data
6	Creating a Data Environment Data environment: Well-organized collection of data of specific type and quality Captured and stored at regular intervals from one or more sources Systematically shared in support of one or more applications
7	Key Issues in Defining A Data Environment
8	Data Sources and Uses
9	Data Aggregation and Structure
10	Data Structure
11	Elements of Data Capture and Management Meta data: Provision of well-documented data environment Virtual warehousing: Supports access to data environment and forum for collaboration History/context: Objectives of data assembly Governance: Rules under which data environment can be accessed and procedures for resolving disputes
12	Projected Outcomes Establish one or more data environments Broad collaboration supporting data environment utilization Implementation of data management processes representing best practices Provide data resources through data.gov initiative Multiple applications developed leveraging multi-source data Research spurs commercialization Applications enable transformational change
13	Getting Involved Provide feedback on program direction, goals, data environment, mobility applications Respond to upcoming funded requests for research and development of mobility applications Seek to leverage the program’s data and applications resources in other non-federally funded research projects Offer new data sets and applications Actively commercialize mobility applications developed within the mobility applications program
