TELUM - Interactive Software for Evaluating Land Use Implications of Transportation Projects

1. TELUM – Interactive Software for Evaluating Land Use Implications of Transportation Projects 11th TRB National Transportation Planning Applications ConferenceMay 6-10, 2007Daytona Beach, Florida

2. Introduction • TELUM is a land use modeling software package that can be used for evaluating land use impacts of regional transportation improvement projects. • TELUM forecasts future location of employment and households • Developed as part of the federal TELUS grant as a standalone modeling software. • Integrated GIS tool

3. Understanding TELUM – Spatial Interaction Model A B D C

4. Motivation • Majority of MPOs neither uses Land Use Models for regional forecasting nor for providing input to travel models. This is due to the lack of trained in-house personnel with experience in land use planning. TELUM is developed as intuitive, interactive software package with many user-friendly features. It is easy to understand, provides tools for easy data entry and analysis, and features Help System that provides instructions and is able to guide and advise users throughout their analysis. It is primarily developed for small and medium-sized MPOs.

5. Why using TELUM? • TELUM enables planners to perform regional land use analysis by: • Forecasting the employment and population that desire to locate in specific zones of a region. • Calculating the amount of employment and population that will be allocated to each zone based on transportation accessibility and underlying economic factors. • Calculating the amount of land needed for locating employment and residential activities.

6. Advantages of TELUM • Inputs consist of US Census data and supplemental data commonly used by MPOs in regional planning process; • User friendly interface makes it easy to navigate through data input, model development, and forecasting process; • On-screen Tip Tools; • Integrated GIS module allows mapping of the input data, calibration results, and forecast results;

7. Transportation Policy Analysis • TELUM provides planners with the ability to compare various transportation improvement scenarios. • Planners can make changes in the transportation network between runs and observe the resulting changes in land use patterns. • Helps decision makers make informed choices about their transportation projects based on their land use impact

8. Land Use Model Outputs – How can they help?

18. Current Program Status • TELUMsoftware package was released in January 2006. It was used by the Pikes Peak Area COG in Fall 06 as part of their new regional transportation plan. Missoula Office of Planning and Grants and Pueblo Area Council of Governments are currently testing TELUM. Used by Des Moines (IA) and Little Rock (AR) MPOs. • Software, User Manual, and Tutorial can be downloaded from TELUS website: http://www.telus-national.org/telum/index.htm • Software is free of charge
