Identifying purpose-based origin-destination using call detailed records

摘要

Access is obtained to call data records (or other data) for a plurality of mobile telephony users. The call data records (or other data) include location-time sequences. For each of the mobile telephony users, corresponding ones of the location-time sequences are segmented into trips; a home-work-school classification model is used to determine a home location and a work-school location, based on the trips; and a trip purpose classification model is used to assign each of the trips a purpose label, based at least on comparing at least one of a start location and an end location for each one of the trips to at least one of the home location and the work-school location determined using the home-work-school classification model. The trips are aggregated into purpose based origin-destination categories based at least on the purpose labels, time ranges of the location-time sequences, and the start and end locations.

主权项

1. A method comprising:
obtaining access to at least one of call data records, location update events, and control events between mobile telephone infrastructure and mobile phones for a plurality of mobile telephony users, said at least one of call data records, location update events, and control events between mobile telephone infrastructure and mobile phones comprising location-time sequences; for each of said mobile telephony users, segmenting corresponding ones of said location-time sequences into trips, each of said trips comprising a start location and an end location extracted from said location-time sequences upon said segmentation; for each of said mobile telephony users, using a home-work-school classification model to determine a home location and a work-school location, based on said trips; for each of said mobile telephony users, using a trip purpose classification model to assign each of said trips between the start location and the end location a purpose label indicative of the purpose of the trips, based at least on comparing at least one of the start location and the end location for each one of said trips to at least one of said home location and said work-school location determined using said home-work-school classification model; and aggregating said trips into purpose based origin-destination categories based at least on said purpose labels, time ranges of said location-time sequences, and said start and end locations.
