Chicago Area Travel Model User Group

CATMUG (Chicago Area Travel Model User Group) was formed in 1997 as a forum to share and discuss travel model research and application efforts among the Chicago area transportation planning community. CATMUG is a multidisciplinary group of over 100 members including engineers, planners, professors, and researchers. CATMUG normally meets at noon on the first Wednesday of each month at CMAP. It is coordinated by Nick Ferguson. Please contact him to be added to the e-mail distribution list.

Topic – The Development and Use of a Rail Freight Commodity Model for the Iowa DOT

Presenter – Ron Eash, Parsons Brinkerhoff

Abstract:
Freight modeling for truck and rail modes is one of the emerging areas of interest in the field of travel demand.  The authors designed and built a rail freight model for the Iowa DOT and the FRA (Federal Railroad Administration) to test planning and operational scenarios for rail in Iowa using Caliper Corporation TransCAD software.  The two-year effort included a number of data processing activities, freight rail network design/construction, and assignment approaches.  Training sessions on the rail freight models were conducted as part of the work effort.  Data used was:

     1. FHWA's Freight Analysis Framework (FAF3.4) Commodity Flow Data.
     2. 2010 Census County Business Patterns.
     3. 2010 Bureau of Economic Analysis local area employment.
     4. Woods and Poole Economics, Inc. long-term county employment forecasts
         for 2040.
     5. Oak Ridge National Laboratory's Center for Transportation Analysis public 
         domain rail network.
     6. U.S. Surface Transportation Board (STB) Carload Waybill Sample (CWB)
         commodity flows prepared from combined 2009 and 2010 year Iowa data.
     7. CWB freight stations inside Iowa identified by railroad and Freight Station
         Accounting Code.
 
The network approach established a verified national rail network, county-level centroid connector scheme, and a means of respecting the individual rail ownership by segment. In Iowa BNSF and UP dominate the rail freight carriers in the state although others are active.  Demand tables (2010 and 2040) are commodity flows by 43 Standard Classification of Transported Goods (SCTG) categories in annual tons, from Freight Analysis Framework (FAF) 3.4 data.  A future year of 2040 commodity flows was developed, with interpolation providing years between 2010 and 2040. 

Chief uses thus far in Iowa are:
     • Diversion tests – the sensitivity of "broken bridges" across the Missouri or
        Mississippi Rivers.
     • Growth scenarios for years between 2010 and 2040.
