REVERSIBLE LANE ACTIVE DIRECTION DETECTION BASED ON GNSS PROBE DATA
First Claim
1. A method comprising:
- receiving a plurality of sequences of instances of probe data by an apparatus comprising a processor and a communication interface, each sequence of instances of probe data being captured and provided by a probe apparatus of a plurality of probe apparatuses, the probe apparatus comprising a plurality of sensors and being onboard a vehicle, wherein (a) an instance of probe data (i) comprises location information indicating a location of the corresponding probe apparatus and (ii) corresponds to a capture time at which the location information was captured and (b) a sequence of instances of probe data are ordered by the capture time corresponding to each instance of probe data;
determining, by the apparatus, a travel direction of each probe apparatus of the plurality of probe apparatuses based on the corresponding sequence of instances of probe data;
matching, by the apparatus, each probe apparatus to a lane of a road segment based on the determined travel direction and a predetermined vehicle lane pattern, the vehicle lane pattern comprising at least one reversible lane;
identifying, by the apparatus, a first number of probe apparatuses and a second number of probe, wherein (a) the first number of probe apparatuses were matched to the reversible lane and have a travel direction of a first direction and (b) the second number of probe apparatuses were matched to the reversible lane and have a travel direction of a second direction apparatuses; and
based on the first number and the second number, determining, by the apparatus, an active direction for the at least one reversible lane.

Abstract
In an example embodiment, a plurality of sequences of instances of probe data are received. Each sequence of instances of probe data is captured and provided by a probe apparatus comprising a plurality of sensors and is onboard a vehicle. An instance of probe data comprises location information indicating a location of the corresponding probe apparatus and the instances are ordered by capture time to form the sequence of instances. A travel direction of each probe apparatus is determined based on the corresponding sequence. Each probe apparatus is matched to a lane of a road segment based on the determined travel direction and a predetermined vehicle lane pattern. The vehicle lane pattern comprises at least one reversible lane. Probe apparatuses matched to the at least one reversible lane are identified. An active direction is determined based on the number of identified probe apparatuses corresponding to each travel direction.
