发明名称 System and method for estimating origins and destinations from identified end-point time-location stamps
摘要 A method and system are disclosed for estimating origin and destination locations of users of a transportation system. The origins and destinations of known users are determined during a segment of an analysis period from validation information for all users of the transportation system. The origins and destinations are then mapped to probable locations associated with the transportation network. A destination probability is then computed for each destination location of an individual origin location. A unknown users are then apportioned to each destination, which may be based on the number of unknown users on a vehicle traveling from the origin to the destination, the computed probability, and the validation information, so as to estimate the number of users traveling from an origin location to any corresponding destination location on the transportation system.

主权项 1. A method for estimating origin and destination locations of users of a transportation system, comprising: acquiring validation information for a set of users of the transportation system, the set of users including a set of unknown users and a set of known users, the transportation system including a set of routes, each route including a set of stops which are selectable by users as origin stops and destination stops; for each of the set of known users, identifying origin stops from the validation information and predicting destination stops, based on the respective identified origin stops, during a segment of an analysis period; mapping at least some of the origin stops and predicted destination stops to respective origin and destination locations associated with the transportation system; based on the origin stops and respective predicted destination stops of the set of known users and the mappings, computing destination probabilities for the destination locations from respective origin locations; apportioning unknown users of the set of users among the destination locations, based on the computed destination probabilities associated with each destination location and the validation information; and estimating destinations of the unknown users traveling from an origin location to a corresponding destination location on the transportation system in accordance with the apportionment, wherein at least one of the identifying, mapping, computing, apportioning or estimating is performed by a processor in communication with associated memory.
