Multiple roadmap DB providers are already available in these days, and try to reduce unknown roads in their own roadmaps. However, cooperation models or Win-Win approaches between roadmap providers are not considered yet. Thus, In this paper, We proposed a cloud-oriented real-time roadmap generation and update method between heterogeneous navigation systems for unknown roads. With the proposed method, the roadmap DB providers update the own roadmap DB for navigation systems in real time. Also, they can provide the complete roadmap without unknown roads to users instantly. Therefore, the proposed method can reduce the costs of an actual traveling test and the maintenance for the roadmap DB provides. Thus, the cloud-oriented roadmap generation method can more efficiently update the unknown road information.

The roadmap DB update for unknown roads is a very important factor for car navigation systems. In this paper, we propose a cloud computing based roadmap generation method for use between heterogeneous navigation system for unknown roads. While the drivers drive on unknown roads, the proposed method extracts the road attribute information, and then generates the metadata in an XML format that is available for the heterogeneous navigation systems in a cloud environment. The metadata is proposed to be used as a replacement for conventional proprietary roadmap formats which used by roadmap providers, which is efficient for heterogeneous navigation system providers in a cloud computing environment. Then, this metadata is provided to the roadmap DB providers through the cloud computing interfaces. With the proposed method, the roadmap DB providers update the own roadmap DB for navigation systems in real time. Therefore, the proposed method can reduce the costs of an actual traveling test and the maintenance for the roadmap DB provides. Thus, the cloud-oriented road map generation method can more efficiently update the unknown road information.

The potential of roadmapping systems in updating, maintaining and sharing technology roadmaps has been argued in many articles but the systems have not been dealt with as a research topic. Therefore, this research purposes to develop an online roadmapping system, which is called an e-TRM system, to improve the efficiency of roadmapping at the national level in Korea. For the purpose, the roadmapping process for national R&D planning and its main activities were analyzed, based on which system requirements and main functions were identified. After the functions were successfully implemented in the TRM system, the system was applied to the 2009 national roadmapping process to verify its feasibility and utility. The system will enable to digitalize R&D planning in Korea and share the planning results nationwide. Also, the research results are expected to provide useful guidelines for those who are in charge of developing TRM systems.
