This project started from the Land Information Ontario GIS layer, with centroids imported from the regional model known as the Greater Golden Horseshoe Model.
The network was converted to a mesoscopic model for the Greater Toronto Area and included all the major freeways, many of which were converted to hybrid models, with microscopic pockets for the planned Pan Am Games HOV lanes.
The modeling team calibrated the regional model prior to subarea extraction to determine the flows in and out of the smaller, city-wide study area. One technique utilized in this process was a time-dependent OD estimation procedure with departure time adjustment.
