Maryland State Highway Administration Pilot of the Data Business Plan Guide for State and Local Departments of Transportation: Data Business PlanChapter 5. Data Governance FrameworkThis section describes the current state of governance processes at Maryland Department of Transportation (MDOT) State Highway Administration (SHA), as well as a recommended framework for mobility data governance. Current StateMDOT Secretary's Office recently hired a Data Chief, indicating that data governance will certainly become a priority. This section is intended to provide background on existing governance processes and documentation. Data Governance Division Data Business PlanIn 2016, SHA created the Data Governance Division (DGD) as a branch of the Office of Planning and Preliminary Engineering (OPPE). One of its missions is to identify a strategic approach to data management agency wide. DGD is developing a Data Business Plan to support overall data management throughout the agency, and to provide a starting point for development of data governance standards and policies for categories of data such as safety, asset, and mobility data.1 The goals of the Plan are as follows:
The Data Business Plan also recommends establishing a Data Management Board to lead the implementation of recommendations and provide oversight for future data business planning efforts. The details and structure of the Data Management Board are still under development. Data Management PlanConsistent with the goals of their Data Business Plan, DGD is developing a Data Management Plan that outlines a plan and data governance framework at SHA to make data more accurate, consistent, defined, secure, and available.2 The goals of this plan are to:
Once complete, the Plan will include the following components: 1) administrative roles and responsibilities for data management; 2) data architecture, including a data inventory, an assessment of existing data sources, metadata standards, and a policy for data creation, collection, and updates; 3) data security requirements, including data auditing, database access control, and schema change management; 4) data availability requirements, including performance monitoring, database development, and backup/recovery; 5) data governance plan; and 6) data governance framework. Data Governance RoadmapMDOT SHA recently contracted with JMT Technology Group to develop a Data Governance Roadmap.3 The project consists of the following tasks:
The effort will result in the development of a strategic plan for implementing data governance at SHA. The strategic plan will include a summary of data governance goals for SHA, the general policies and standards to be implemented, and specific actions to achieve those goals. Enterprise GISSHA Geospatial Metadata StandardsThis document describes how to create and update metadata for geospatial data in the eGIS. Metadata content is summarized in table 3.4 SHA Geospatial Data Policy and StandardsThis document establishes the Maryland SHA GIS policy and standards for the format of geospatial data that is acceptable for incorporation into the eGIS systems of the Administration.5 The policy addresses data standards and its operations in the context of data life cycle phases, including planning, collection and acquisition, processing and documentation, storage and access, and maintenance and retirement. GIS Data Delivery StandardsThis document specifies standards for data delivery for all data layers developed for projects that have a GIS component.6 Standards are specified for acceptable file formats, coordinate system, metadata, and media. eGIS Data Catalog The eGIS Data Catalog contains a data catalog for eGIS contents. The data catalog identifies geospatial datasets and descriptive metadata such as data layer name, health status, dataset purpose, contact information, update frequency, map scale, geometry type, data category, source location, etc. The eGIS Data Catalog currently includes Fund 77 Active Projects, Annual Average Daily Traffic, Structures, Green Asset Management System, Highway Lighting, Line Striping, Park and Ride, and Rumble Assets. The vision for eGIS is to complete an inventory of all data sets within SHA. Open ArchitectureSHA has adopted open architecture as a basic information processing strategy to ensure information is available to the people authorized to receive it, regardless of the specifics of their computing platform. SHA developed computer architecture standards for information technology that describe the current computing environment, including software, network environment, hardware requirements, and security requirements.7 Mobility and Economy DashboardAnnual Mobility Reporting and Mobility DashboardSince 2012, Maryland SHA has been producing an annual Mobility Report. The mobility report demonstrates SHA's focus on applying a performance-based approach to provide a high quality and reliable highway system. In 2014, SHA improved accessibility to the contents of the Mobility Report by creating a web-based Mobility Dashboard. Mobility Dashboard Data CatalogThe Mobility Dashboard Data Catalog identifies mobility and economy datasets used to support the Mobility Dashboard. The data catalog provides descriptive metadata such as the target location, source data layers, dependent-derived data sets, data owner, data steward, update frequency, historical data storage process, data format, processing requirements, dependent reports or applications, recurring deadlines for data, stakeholders, and map service supported. The eGIS Data Catalog includes bike routes, congestion costs, counties and regions, HOV lanes, MDTA tolls, Park and Ride locations, pedestrian sidewalk locations, Consolidated Transportation Program (CTP) projects, reliability (planning time index), reversible lanes, Traffic Message Channel (TMC) segments, transit-oriented development location, congestion (travel time index), and volume data. Other mobility datasets are listed in the data catalog but are not included in the current version of the dashboard. Mobility and Economy Dashboard Database Architecture GuideThis document describes the Mobility and Economy Dashboard database architecture.8 The basic structure is a customized relational database management design that allows for retrieval of statistical information based on user input and interaction. The architecture consists of the following components: TMC segments, locations, trends and measures, projects, programs, policies, and lookup and reference tables. Consolidated Transportation Program (CTP) ProjectsThe Consolidated Transportation Program (CTP) is Maryland's six-year capital budget for transportation projects and programs across the DOT. MDOT SHA maintains spatial data for major and minor projects in the CTP. The CTP Projects Data Processing document describes standards for CTP spatial data format, including project details, project location, financial information, and construction status.9 Recommended Governance FrameworkThere is a good process in place, and the Data Governance Roadmap project will continue SHA's initial efforts to develop and implement an enterprise governance framework. It is recommended that governance for mobility data complement and leverage efforts at the enterprise level. This section recommends a data governance framework for mobility data in the region. This includes adopting core data principles, implementing a data governance model, defining roles and responsibilities for managing mobility data, and developing supporting documents such as a Data Governance Manual, Data Catalog, Business Terms Glossary, and Data Sharing Agreements. Data PrinciplesIt is recommended that SHA adopt core data principles to guide mobility-related decisionmaking. The following set of core data principles are recommended by the AASHTO Subcommittee on Data.10 These data principles are also applicable for enterprise level governance efforts.
Data Governance ModelA data governance model depicts the relationship between the mobility data programs, the various individuals/agencies responsible for implementing data governance, and the users/stakeholders for the data programs. The model diagram in figure 2 proposes a formal structure for mobility data governance for MDOT SHA. The proposed governance model builds on current governance initiatives and includes the following components:
Roles and ResponsibilitiesTable 4 defines the roles and responsibilities for supporting the governance framework. These roles/responsibilities should be vetted with the Data Management Board. The roles and responsibilities listed are job functions and not necessarily job titles. In some cases, the duties of a data owner, data steward, and data custodian may be performed by the same individual.
Rules of EngagementOnce the Mobility Data Working Group has been formally established, the group should develop and approve a Charter to set forth the purpose, goals, membership, roles and responsibilities, meeting schedule, and "rules of engagement" regarding collaboration and coordination for the group. Potential rules of engagement could include the following:
An example data sharing agreement is provided in appendix D. Governance DocumentationOnce the Mobility Data Working Group has formally approved a Charter, the group should also develop and approve the following supporting documents to define policies, standards, and procedures for data governance in the region:
