• Abstract:
  The purpose of this research study is to evaluate the most appropriate traffic forecasting tool that is most responsive to the needs of the South Dakota Department of Transportation (SDDOT). Like many other state agencies, the SDDOT has to do more with less funding for transportation infrastructure, operation, maintenance, and planning. The traffic forecasting functionality has to be tailored to SDDOT’s needs and constraints while maximizing benefits. The interviews of SDDOT stakeholders strongly emphasize the desire for a better forecasting approach than the current 20-year traffic forecasting procedure. The research team evaluated the uses/ needs of traffic forecasts at SDDOT against the availability of data, budget, and staff. While it is possible to build a statewide travel model (STM) of sketch planning type using available data, the applicability of such a model would fall short of meeting many of the identified uses and needs that are largely project specific. However, building a more robust 4-step STM that would satisfy many of the uses/ needs requires travel behavior data currently unavailable. Considering the advantages and disadvantages, the research team does not recommend a four-step statewide model at this stage. A more practical approach in the short-term is to enhance the current 20-year traffic forecasting procedure, use of GIS and transportation planning software, and staff training in travel demand forecasting. A sketch planning type STM is recommended in the short-medium term together with future enhancements that include a regional model option, and 4-step STM for passenger and freight.
