1. A method of determining origin-destination (OD) data for a transportation system, the method comprising:
by a processing device, receiving passenger statistics collected from a plurality of data collection devices deployed throughout a transportation system; by the processing device, developing a model representing passenger usage of at least a portion of the transportation system, the model comprising a network that comprises:
a plurality of nodes, wherein each of the plurality of nodes represents a geographical area of the transportation network, anda plurality of links, wherein each of the plurality of links represents one or more transportation routes that connect two of the plurality of nodes; by the processing device, determining link utilization rates for each of the plurality of links by applying the passenger statistics to the model, wherein each link utilization rate represents a measurement of passenger usage of its corresponding link; for each link, by the processing device:
determining a cost of the link based on at least computing a proportion of passengers that travel over that link, andusing each determined cost to determine a likelihood that a passenger will select the link to reach a destination; by the processing device, generating an observation report comprising each determined likelihood for each link and an origin-destination matrix for at least the portion of the transportation system so that the origin-destination matrix comprises the determined link utilization rates; and outputting, by the processing device, a results set including at least a portion of the observation report. |
