Abstract
A transport service system identifies a map matched trajectory for a transport vehicle based on planned route information and location data associated with a trip. The system receives planned route information and location data for a transport vehicle. For each location data point, the transport service system identifies a set of candidate road segments. Sequential pairs of candidate road segments represent transitions. The system uses a map of the corresponding area to calculate a transition probability, the likelihood of traversing from the first candidate road segment to the second candidate road segment. The system identifies transitions that correspond to the planned route and adjusts the transition probabilities based on the identified planned route transitions. Based on the adjusted probabilities, the transport service system determines a most-likely traversed path for the transport vehicle.
