Dynamic Traffic Assignment (DTA) models estimate and predict the evolutionof congestion through detailed models and algorithms that capture traveldemand, network supply and their complex interactions. The availability ofrich time-varying traffic data spanning multiple days, collected by automaticsurveillance technology, provides the opportunity to calibrate such a DTAmodel’s many inputs and parameters so that its outputs reflect field conditions.DTA models are generally calibrated sequentially: supply model calibration(assuming known demand inputs) is followed by demand calibrationwith fixed supply parameters. This book develops an off-line DTA modelcalibration methodology for the simultaneous estimation of all demand andsupply inputs and parameters, using sensor data. A complex, non-linear,stochastic optimization problem is solved, using any general traffic data. Casestudies with DynaMIT, a DTA model with traffic estimation and predictioncapabilities, indicate that the simultaneous approach significantly outperformsthe sequential state of the art. This book is addressed to professionalsand researchers who apply large-scale transportation models.
