Testing Results

Demographic forecasts were input to the modeling process to generate future travel demand values.  Network changes resulting from the addition of improvement projects were used to define the action scenarios based on the year the proposed improvement would likely be constructed.  The combination of demographic changes and network changes were ran through the modeling process, and resulted in the overall estimates of VMT, VHT, and emissions generated in the SJTPO region.  A summary of the population, employment, VMT, and VHT values generated in the SJTPO region is found in Table 7-3 below.  The VMT and VHT data is summarized by analysis period, winter or summer, and is presented for comparative purposes.
