The paper deals with simulation of congested urban areas through dynamic traffic assignment models and presents a new quasidynamic traffic assignment model that improves realism and effectiveness of both usual static traffic assignment models and other quasi-dynamic models recently introduced in the literature. The new model has been applied to a real large-scale road network (the town of Rome) and has been validated through a comparison with a very large set of floating car data. Results of validation reveal that the quasi-dynamic traffic assignment model provided a rather satisfactory goodness of fit, which is comparable with that reported in literature as a result of application of a much more sophisticated simulation and calibration procedure, applied to a road network having similar characteristics of size and congestion degree.

Abstract

The paper deals with simulation of congested urban areas through dynamic traffic assignment models and presents a new quasidynamic traffic assignment model that improves realism and effectiveness of both usual static traffic assignment models and other quasi-dynamic models recently introduced in the literature. The new model has been applied to a real large-scale road network (the town of Rome) and has been validated through a comparison with a very large set of floating car data. Results of validation reveal that the quasi-dynamic traffic assignment model provided a rather satisfactory goodness of fit, which is comparable with that reported in literature as a result of application of a much more sophisticated simulation and calibration procedure, applied to a road network having similar characteristics of size and congestion degree.
