Maryland State Highway Administration Pilot of the Data Business Plan Guide for State and Local Departments of Transportation: Data Business Plan

Chapter 4. High Level Architecture

The second component of the Data Business Plan (DBP) Framework is the architecture that is a high-level description of the interaction between databases and tools to support use of the integrated mobility data. The following draft High Level Architecture was developed during the Data Business Planning process.

The architecture depicts that a variety of data sources would feed through Metropolitan Planning Organizations (MPO), Coordinated Highways Action Response Team (CHART), State Highway Administration (SHA) Geographic Information System (GIS), Regional Integrated Transportation Information System (RITIS), and other databases. The data would then be used to support planning or real-time analyses and ultimately be accessed through the Multimodal Mobility Framework.

It is intended to be a draft and should be discussed and refined by Maryland Department of Transportation (DOT) SHA as part of the implementation of this DBP.
