Electronic nervous system for a roadway and method
First Claim
1. An electronic nervous system for a roadway, comprising:
- a plurality of symbolic patterns;
an electronic information path that parallels the roadway, the plurality of symbolic patterns traveling along the electronic information path; and
a processor coupled to the electronic information path and deriving at least one of the plurality of symbolic patterns, the processor extracting at least one of the plurality of symbolic patterns from the electronic information path, the processor determining a state of the roadway by comparing two of the plurality of symbolic patterns.

Abstract
An electronic nervous system (10) for a roadway (12), has a plurality of nodes (14). The plurality of nodes (14) parallel the roadway and are connected by an information link (20). A plurality of sensors (16) are coupled to the plurality of nodes (14) and the output of the sensors (16) are processed by the nodes to form symbolic patterns (18). The symbolic patterns (20) travel along the information link (20). By comparing symbolic patterns (18) the state of the roadway (12) can be determined. The state can include a metric that measures how well traffic is flowing as well as determines transit times between nodes. A plurality of traffic signals (34) are coupled to the nodes (14) and are adjusted based on the symbolic patterns (18). A subset of the plurality of nodes (14) are coupled to a node supervisor (36).
