摘要：	Microscale modeling applications for corridor and subarea traffic operations analysis have become an instrumental element in the traffic engineer's toolbox. These modeling applications, while revolutionary in providing the analyst with the capabilities of dynamic evaluation of alternate concepts, require a significant level of data and include a broad range of assumptions. Key inputs to the models are traffic volumes. The source of these volumes are many times macroscale travel demand forecasting models. These macroscale models may have initially been developed for use in the long-range transportation planning process for the region or have been adapted from the regional model for more detailed application in a specific corridor or subarea. A key focus of the microscale applications over the macroscale operations models has been in reformulating the methods applied in distributing traffic over the analysis period. The applications to date have been successful in obtaining a significant level of support in the analysis advancements, however, the traffic inputs are many times simply products of travel demand model applications developed for macroscale purposes. In reality, the traffic forecasting models need to be adapted prior to expecting the products to be reasonable for use in microscale applications. The purpose of this paper is to provide documentation of a number of alternates evaluated in attempting to establish a methodology for developing peak-hour travel data from an initial regional model for application in a microscale subarea analysis. Within the paper, the strong and weak points of each of the alternate applications evaluated as part of a subarea study are documented. A primary purpose of the subarea study in Lincoln, Nebraska was to develop a subarea analysis methodology for application throughout the metro area. It has been the hope of the authors that the methods in this paper could be used as a beginning point, or to add to the current set of knowledge, for establishing a convenient, reasonable link that would allow regional travel model outputs to be a source for microscale corridor applications.
