1. A method for determining a vehicle trip on a roadway, the method comprising:
- providing a plurality of vehicle detections from a plurality of gateways;
determining a maximum travel time between corresponding pairs of the plurality of gateways;
correlating corresponding pairs of the plurality of vehicle detections by determining travel time between each of the gateways of each of the corresponding pairs of detections is less than a corresponding maximum travel time;
determining a plurality of chainable detections; and
determining the boundaries of the trip.

Abstract
A method for determining a vehicle trip on a roadway includes providing a plurality of vehicle detections from a plurality of gateways, determining a maximum travel time between corresponding pairs of the plurality of gateways, correlating corresponding pairs of the plurality of vehicle detections by determining that a travel time between each of the gateways of each of the corresponding pairs of detections is less than a corresponding maximum travel time, determining a plurality of chainable detections, and determining the boundaries of the trip.
