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

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.
• Determination of the State of the Practice in
  Metropolitan Area Travel Forecasting Findings of
  the Surveys of Metropolitan Planning
  Organizations, April 7, 2006, Prepared for
  Committee B0090, TRB/National Research Council

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.

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

Current Program Status

• TELUM software 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-na
  tional.org/telum/index.htm
• Software is free of charge
