1. A system for monitoring a vehicle travelling along a roadway comprising:

  • a first means for measuring magnetic signatures of predetermined points along said roadway wherein said predetermined points are used to generate a connection graph corresponding to distinct pathways within said roadway;

    a second means for measuring magnetic signatures that is located in said vehicle travelling along said roadway;

    a non-transitory computer readable medium with computer executable instructions stored thereon executed by a processor to transmit said magnetic signatures measured by said second means for measuring magnetic signatures from said vehicle;

    a server to generate said connection graph based on said magnetic signatures of predetermined points, wherein said server receives said transmitted magnetic signatures from said vehicle, and wherein said server compares said received magnetic signatures to said magnetic signatures in said connection graph to determine path of said vehicle along said roadway; and

    a database for storing said magnetic signatures in said connection graph and said magnetic signatures received from said vehicle travelling along said roadway.
