Abstract:
1. A method for forecasting future economic conditions, land utilization and transportation network utilization and performance of a metropolitan area having a plurality of economic zones, said method comprising the steps of: a) receiving a set of calibration values from a first input device; b) calculating a set of calibration constants with a first arithmetic logic unit, based on the set of calibration values; c) receiving a set of initial values for a set of desired outputs from a second input device, wherein said set of desired outputs comprises regional economic, land use and transportation outputs; d) calculating said regional economic and land use outputs with a second arithmetic logic unit, wherein an initial calculation of said regional economic and land use outputs is based on a portion of the set of initial values and said regional economic and land use outputs comprise a first group of variable travel demands; e) calculating an origin to destination matrix with a third arithmetic logic unit, wherein an initial calculation of said origin to destination matrix is based on a portion of the set of initial values and said origin to destination matrix comprises two-way daily person trips between an origin economic zone and a destination economic zone according to the equation where P ijk|f =P ijk|f (p R , R, w, M f , G, g) and Z j|isf =Z j|isf (p R , w sf , M f , G is , g is , G j , g j ); f) calculating said transportation outputs with a fourth arithmetic logic unit, wherein an initial calculation of said transportation outputs is based on a portion of the set of initial values and said transportation outputs comprise a second group of variable travel demands; h) repeating steps d) through f) until said first group of variable travel demands is substantially the same as said second group of variable travel demands; and, g) providing said set of desired outputs to an output device.
