High accuracy geo-location system and method for mobile payment

A method for improving tolling accuracy in an automated location-based tolling system, comprising:

• defining, by a backend server, at least one geofenced toll region corresponding to a toll portion of a roadway for which a toll is charged;
• defining, by the backend server, an associated geofence region corresponding to a non-toll portion of a roadway, wherein the toll roadway and non-toll roadway are geographically proximate to each other;
• a mobile device determining its location using a satellite location receiver of the mobile device periodically to produce a plurality of location fixes which each indicate a location which includes an inherent location inaccuracy;
• the mobile device transmitting the plurality of location fixes to the backend server;
• in response to receiving the plurality of location fixes the backend server automatically comparing the plurality of locations of the plurality of location fixes with the at least one geofenced toll region and the associated geofence region;
• the backend server determining that the plurality of locations include at least one location in the at least one geofenced toll region and at least one location in the associated geofenced region;
• and
• the backend server inhibiting a toll transaction from occurring, for a toll account associated with the mobile device, responsive to determining that the plurality of locations include at least one location in the at least one geofenced toll region and at least on location in the associated geofenced region wherein the toll transaction would have otherwise occurred due to the backend server determining that at least one location of the plurality of locations is in the at least one geofenced region corresponding to the toll portion of the roadway.
