Traffic management system including a layered management structure
First Claim
1. A traffic management system (TMSYS) for managing in a road network (RDN) the vehicle traffic (C1, Cx) on a physical layer (PL), said traffic management system (TMSYS) comprising a layer structure including at least:
- a) a traffic signalling layer (TSL) including a plurality of traffic signalling units (TSU) for monitoring and/or controlling the vehicle traffic (C1, Cx) and a traffic signalling layer information exchange interface (TSL-EX) adapted a1) to output traffic signalling information (TSI) about the vehicle traffic (C1, Cx) on the physical layer (PL);
a2) to receive traffic control information (TCI) for controlling the vehicle traffic (C1, Cx); and
a3) to output traffic guidance information (TGI) to the vehicles (C1, Cx) on the physical layer (PL); and
b) a traffic control layer (TCL) including a packet switched control network (PSCN), in which the packet traffic (CP1, CPx) is controlled with a predetermined packet control method to correspond to or simulate the vehicle traffic (C1, Cx) on the physical layer (PL), including a traffic control layer information exchange interface (TCL-EX) adapted b1) to receive traffic signalling information (TSI) about the vehicle traffic (C1, Cx) on the physical layer (PL);
b2) to output traffic control information (TCI) for controlling the vehicle traffic (C1, Cx);
b3) to output packet signalling information (PSI) about the packet traffic (CP1, CPx); and
b4) to receive packet control information (PCI) for controlling the packet traffic (CP1, CPx) in the packet switched control network (PSCN).

Abstract
The invention relates to a traffic management system (TMSYS) including a layered structure of management layers. The system comprises a physical layer (PL) on which the actual traffic takes place. A traffic signalling layer (TSL) controls the traffic on the physical layer (PL) and collects traffic information (TSI) about the vehicle traffic. A traffic control layer (TCL) comprises a packet switched control network (PSCN) for routing packets to correspond or simulate the vehicle traffic. A service application layer (SAL) provides special services to the traffic control layer (TCL) and/or the traffic signalling layer (TSL). A communication layer (CL) is used for communicating the information. Each layer comprises an exchange interface for receiving/transmitting information to one or more of the other layers. The layered structure of the traffic management system allows in particular a flexible adaptation, exchange or extension of functionalities provided in each layer.
