With the increasing application of macroscopic travel demand models and microscopicsimulation models within the same project, the need for integrating models in different levelsto facilitate transferring data is becoming essential. This paper describes an example projectwhere an integrated macroscopic-microscopic model was applied to perform analyses atdifferent levels of detail. The example project was a freeway corridor application inPortland, Oregon using the integrated PTV Vision Suite software. The level of integratedenabled network consistency to be maintained across models used for different projects,facilitated the development of 15-minute O-D matrices and paths and expedited the coding ofgeometry data and signal timing plans for local intersections and ramp meters. Ultimately,the integrated workflow saved a considerable amount of time and allowed the 3-monthproject to be delivered on schedule. Also, integrated network now can be used for anyadditional project with minimal effort.
