TRAVEL DEMAND MODEL CALIBRATION FOR AREAS WITH HETEROGENEOUS CHARACTERISTICS

This article describes the methodology that was successfully used to address problems posed by spatial heterogeneity during the calibration of he RADCO (Rappahannock Area Develpment Commission) travel forecasting model. The case study background is described. The MINUTP computer software package was used to develop the RADCO regional travel forecasting model (RRTFM). Data collection and development is described. The three steps are described of the calibration of the RRTFM: trip generation submodel calibration; trip distribution submodel calibration ; and the traffic assignment submodel calibration. The evaluation of the traffic assignment results is also described. It was found that variations between the ground counts and the assigned volumes for the individual links fell well within their respective maximum tolerable errors.
