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.
