1. An apparatus comprising at least one processor and at least one non-transitory memory including computer program code instructions, the computer program code instructions configured to, when executed, cause the apparatus to at least:
receive a plurality of probe data points, wherein the plurality of probe data points comprise at least a location and a timestamp associated with a respective probe data point;
map-match the plurality of probe data points to one or more road segments of a road network;
determine, for the plurality of probe data points, lanes of travel of the one or more road segments;
determine a non-zero volume of traffic along each lane of the lanes of travel of the one or more road segments based on the lanes of travel of the one or more road segments determined for the plurality of probe data points;
determine an expected volume of traffic along each lane of the lanes of travel of the one or more road segments;
generate an indication of a lane closure in response to a non-zero volume of traffic along a first lane of travel of the one or more road segments being a predetermined amount below an expected volume of traffic for the first lane of travel of the one or more road segments; and
provide for at least one of route guidance information or at least semi-autonomous vehicle control in response to the indication of the lane closure.
 
10. A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code instructions stored therein, the computer-executable program code instructions comprising program code instructions to:
receive a plurality of probe data points, wherein the plurality of probe data points comprise at least a location and a timestamp associated with a respective probe data point;
map-match the plurality of probe data points to one or more road segments of a road network;
determine, for the plurality of probe data points, lanes of travel of the one or more road segments;
determine a non-zero volume of traffic along each lane of the lanes of travel of the one or more road segments based on the lanes of travel of the one or more road segments determined for the plurality of probe data points;
determine an expected volume of traffic along each lane of the lanes of travel of the one or more road segments;
generate an indication of a lane closure in response to a non-zero volume of traffic along a first lane of travel of the one or more road segments being a predetermined amount below an expected volume of traffic for the first lane of travel of the one or more road segments; and
provide for at least one of route guidance information or at least semi-autonomous vehicle control in response to the indication of the lane closure.
 
18. A method comprising:
receiving a plurality of probe data points, wherein the plurality of probe data points comprise at least a location and a timestamp associated with a respective probe data point;
map-matching the plurality of probe data points to one or more road segments of a road network;
determining, for the plurality of probe data points, lanes of travel of the one or more road segments;
determining a non-zero volume of traffic along each lane of the lanes of travel of the one or more road segments based on the lanes of travel of the one or more road segments determined for the plurality of probe data points;
determining an expected volume of traffic along each lane of the lanes of travel of the one or more road segments;
generating an indication of a lane closure in response to a non-zero volume of traffic along a first lane of travel of the one or more road segments being a predetermined amount below an expected volume of traffic for the first lane of travel of the one or more road segments; and
providing for at least one of route guidance information or at least semi-autonomous vehicle control in response to the indication of the lane closure.
