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 probe data from a plurality of probe apparatuses traveling along a sequence of road segments; receive sensor data associated with the probe data, wherein the sensor data comprises data captured by sensors of the probe apparatuses along the sequence of road segments; identify, from the sensor data, one or more indicators of a beginning of a road work area; identify, from the sensor data, binary indicators of a presence of road work or a lack of road work along the sequence of road segments; determine, based on the one or more indicators of the beginning of a road work area and the binary indicators of the presence of road work or the lack of road work along the sequence of road segments, a probability of road work occurring along one or more road segments of the sequence of road segments; provide an indication of the probability of road work occurring along the one or more road segments of the sequence of road segments for at least semi-autonomous vehicle control; determine a confidence of road work occurring along the one or more road segments of the sequence of road segments based on the probability of road work occurring along the one or more road segments of the sequence of road segments and a time decay factor since the sensor data was collected; and cause an autonomous vehicle to cede control of the vehicle to a driver based on the indication of the probability of road work occurring along the one or more road segments of the sequence of road segments and the confidence satisfying a predetermined threshold.
