The objectives of this study were to integrate road networks to provide a comprehensive road network through the use of multiple public sources and to provide guides for performing a quality control assessment before delivering data and using the data for geospatial analysis. The study focused on the Fort Berthold Reservation in western North Dakota. A method is proposed to integrate multiple public road networks to support a tribal transportation agency. The workflow and techniques proposed are transferrable to other tribal transportation agencies. Depending on current data used for transportation planning and operations, the workflow and processes are subject to change from agency to agency, but the study provided general guidance for the agency. The study recommended that the tribal transportation agencies develop linear referencing systems on the proposed road network to adopt efficient asset management and version control. The linear referencing system should comply with state or federal guidelines for improved communication. To develop appropriate applications, the road network should include additional attributes based on the needs of the reservation.
