One of the system planning tools developed for statewide transportation planning in Indiana is a customized version of the Federal Highway Administration (FHWA) Highway Economic Requirements System (HERS) entitled HERS_IN. The HERS_IN model was developed with consultant assistance from Cambridge Systematics, Inc., to provide a system planning tool for the identification of highway capacity needs and potential improvement projects. The major modifications for the HERS_IN system focus on the analysis of added travel lanes projects on the existing highway system, the use of the Indiana Department of Transportation (INDOT) corporate database, the road inventory system, to provide a 100% sample for the state highway system, and the use of a geographic information system (GIS) approach for statewide mapping and display. The FHWA national model is based upon a sampling system, using Highway Performance Monitoring System (HPMS) data, which allows the number of miles of highway improvements to be estimated, but not the location of the improvement. HERS_IN by having complete highway data and using the TransCAD GIS allows the specific identification of the needed highway projects in addition to systemwide analysis of highway investment. HERS_IN identifies needed added travel lane improvements by calculating highway capacity deficiencies over the year 2000 to 2025 planning period. Traffic growth rates from the TransCAD based Indiana Statewide Travel Demand Model are used to identify future year traffic volumes on specific highway links. HERS_IN evaluates future highway deficiencies using a cost/benefit economic analysis approach to identify the need for an added travel lanes project and the most appropriate time period to make the improvement. HERS_IN identifies a potential added travel lanes project, calculates the estimated cost of the improvement, compares that to the project benefits (travel time savings, reduced accidents, and vehicle operating expense), and assigns the improvement to one of five improvement phases on the basis of a cost/benefit ratio. HERS_IN provides a statewide highway analysis tool which allows the testing of a wide range of "what if" scenarios. The analysis can evaluate the system performance impacts of using different levels of benefit/cost ratios to select highway investments, the use of different capacity levels to identify deficiencies, and the use of alternative levels of investments. The HERS_IN analysis at this time, is limited to the evaluation of the existing highway system. The analysis of new highway links, such as new intercity highways providing new connections, need to be evaluated through other system planning tools such as the statewide travel demand model. The HERS_IN analysis system provides an important statewide analysis capability to the overall Indiana planning process and in addressing the statewide planning requirements of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) and the Transportation Equity Act for the 21st Century (TEA-21) legislation.
