Identification of Communication Solution designated for Transport Telematic Applications

Communications solution represents one of the key parts of the Intelligent Transport system (ITS). Goal of our research is to improve over-ground traffic efficiency and security, specifically on the airport territory, where pilot installation was set-up and tested with aim to confirm its ability to improve conditions for efficient management of the over-ground traffic of all moving object in area including moving aircrafts and all types of service vehicles. ITS system requirements on the communications environment are usually quantified indirectly by telematic sub-system performance indicators. Correct selection and configuration of the appropriate communication solution are achievable, if "transformation matrix" between vectors of communications and telematic performance indicators is correctly identified. Principles of developed method based on such transformation matrix identification are introduced. Application of the proposed methodology is demonstrated on the CaMNA communications system identification and its parameters settings. Airport territory has got quite complex arrangement and there are very different requirements on telematic system performance in different parts of the airport area. This fact leads to application core wireless access service securely combined with set of the alternative technologies applied in areas, where the core service is not available for technical or economical reason. Management of such system is based on implementation of the CALM family of standards or its mutations with implemented effective and safe decision processes. Correctly designed decision processes supporting selection of the “best possible” alternative represent one of key issues of the whole solution. Results of the communication solution parameters tests processed within limited pilot installation and relevant recommendations are presented as the last part of this paper.
