    Abstract: An apparatus and method for inferring optimal pick-up/drop-off locations for transport services use historical bookings data associated with past bookings, the past bookings having a pick-up or drop-off location within a defined geographical area. Each historical data instance for a booking includes a geographical data point recorded at a time of a pick-up/drop-off event within the geographical area. The historical data is processed to identify clusters of geographic data points having similar geographical locations. A quality indicator is determined and compared with a first threshold. If the quality indicator satisfies the first threshold, a cluster centroid for each cluster is designated as an optimal pick-up/drop-off location for the geographical area.
