In this project, we analyze the relationships between several different integrated modeling packages which capitalize on the feedback mechanism between land-use forecasting and transportation-related accessibility metrics. Our focus here is not on the optimal feedback mechanism but on the value-added for increasing resolution (including complexity and disaggregation) in an integrated framework. Increased resolution can mean different things for travel-demand models and land-use models. As described previously, microsimulation traffic models are capable of modeling traffic flow at the individual vehicle level, but travel model resolution can also be increased by including all of the transportation infrastructure in the travel network (not just major roadway links) and specific characteristics of intersections and modal transfer points. Travel-demand, though, is commonly assessed at the level of a polygon-based traffic analysis zone (TAZ), which aggregates all travel to/from it into a single centroid-node. The resolution of the TAZ may not be compatible with the resolution of the microsimulation traffic network.
