      <title>RES2020-18: Developing Statewide Land Use Forecasting Model and Integrate with TDOT's Statewide Travel Demand Model</title>
      <link>https://rip.trb.org/View/1716835</link>
      <description><![CDATA[In this research, a statewide forecasting land-use model is presented. The land-use model is called the LargeScale Land Use Model (LS-LUM) and can be integrated with Tennessee Statewide Travel Demand Model (TSM
v3). Massive data collection was followed in this project and households’ information, employment information,
housing information was collected at the Traffic Analysis Zones (TAZ) level. Moreover, parcel data for 94 counties
were collected to be incorporated into the model. The model is developed for the base year 2010 and forecasts the
demographic and socio-economic condition of the state of Tennessee from 2015 to 2050 with five years intervals.
The developed model is validated using the backcasting approach and the goodness of fit and error measures are
provided to show the accuracy of the model. To present the result of the model, an online dashboard is created
providing forecasting results from 2015 to 2050 at TAZ and County levels Moreover, the online dashboard
presents a brief statistical analysis. The developed land-use model is integrated with TSM v3 and results are
provided. Since the model incorporates house conditions (total houses and vacant houses) and land use conditions
in each TAZ (residential, commercial, industrial, agricultural, and developable lands), it provides a powerful tool
for policy analysis. A software is developed for running the model using MATLAB Compiler Runtime, which
enables sharing the model with other parties.

      <title>Modeling Transportation Alternatives</title>
      <link>https://rip.trb.org/View/1357382</link>
      <description><![CDATA[This project develops an "outreach model" that isolates and simplifies the most essential dynamics of the complete integrated model in a way that is more transparent and that facilitates outreach to stake holders. The immense complexity of the combined UrbanSim and TRANSIMS models complicates any attempts to facilitate outreach with stakeholders. A simplified systems oriented "outreach model" will be designed to facilitate such outreach and dialogue. The purpose of this model is to help convey to stakeholders how transportation issues relate to the other major issues with which they are interdependent, including land use, energy, economics, environment and quality of life. Through a web interface stakeholders will be able to run their own simplified versions of the model under different scenarios and vary parameters in a way that makes the key dynamics and assumptions of the model clear and easy to understand. If there is general convergence between the results of both, this may be a good indication of the overall robustness of both approaches. If there is extreme difference in the results, an analysis of the sources of these differences may help us better understand some of the sensitivities and assumptions of both model approaches. Development of the outreach model will consist of the following tasks: * Regular stakeholder workshops to verify model design and components, to review preliminary results, and to design and review scenarios. * Intensive model development activities between workshops. This would include model coding, calibration, and testing, as well as development of user interfaces. Existing more complex models (i.e. URBANSIM) would be used for cross-calibration and testing. * Problem-based (atelier) courses structured around the project and involving students from many departments on campus. * Web-based outreach. A sophisticated, interactive web site will be developed that will serve to connect stakeholders during project development and to serve as the major portal for delivery of the Integrated Modeling Package after completion.]]></description>
