Analysis of planning constraints and application scenarios for communication in transportation systems

This paper presents different use cases and scenarios for communication in transportation systems. Thereby, it highlights their differences in terms of planning constraints. Some existing networks and their parameters are introduced. Based on that, strategies for hybrid use of the same communication network infrastructures for different purposes are analyzed. Finally, protocols for interworking of existing networks are described to include hybrid use in the different network specifications. This shows the possibilities for hybrid networks already existing and gives an outlook on what to include in future network design to further allow hybrid use in combination with existing infrastructure.
