Estimating Future Travel Demand: Linking ArcView GIS with TMODEL2 Author: James R West 1201 Walnut Phone: 816-527-2497 Travel demand models are an effective means of estimating future travel demand. However, these models fall short of allowing planners to analyze, manipulate, and display the data in a meaningful way. It is also sometimes difficult to estimate transportation needs based on land uses and development that constantly change. A discussion will be presented on the development of a link between Olathe's GIS (ArcView GIS) and their travel demand model (TMODEL2), and how it allowed planners to exchange valuable data between the model and take advantage of GIS capabilities. Land use data, stored in the GIS, can be adjusted to develop and test different land use scenarios. This data can be uploaded to the travel demand model for quick and easy analysis. In addition, travel demand data generated by the model can be downloaded to the GIS for more thoughtful analysis and display of model output. The link between the travel demand model and the City's GIS is a unique tool that has been developed using the ArcView GIS Avenue programming language in combination with C++ and Visual Basic for Applications programming languages. With this new tool, travel demand model data is now more accessible and usable to a wide range of City staff. |
