Bicriterion traffic equilibrium : T2 model, algorithm, and software overview Dial, Robert B

By: Dial, Robert BPublication details: Transportation Research Record, 2000Description: nr 1725, s. 54-62Subject(s): USA | Mathematical model | Traffic assignment | Equilibrium | Stochastic process | | Journey time | 11Bibl.nr: VTI P8167:1725Location: Abstract: T2 is a rational and rigorous bicriterion traffic assignment model developed around a stochastic linear generalized cost model, which forecasts path choices and consequent equilibrium link volumes of trip makers with diverse values of time. Its path choice criterion minimizes a disutility equaling a stochastic sum of two link attributes--usually time and cost--both of which may be flow dependent. In contrast with the classical traffic assignment model, T2 permits different travelers to respond differently (as a result of factors such as travel time, tolls, congestion, taste, etc.) to the same path choices. This research provides an overview of T2's mathematical model, solution algorithm, and implementing software.
