Table 11. Estimation Process for Average Household Person Miles Traveled by Selected Household Types
Dataset Table:
| Variable | Calculated difference (proportion) | One person household zero vehicles available | One person household with 1 vehicle available | Two person household with 1 vehicle available | 1 |
|---|---|---|---|---|---|
| (A) | (Table 9)*(1 + (A)) | (Table 9)*(1 + (A)) | (Table 9)*(1 + (A)) | 2 | |
| Person miles traveled | 0.192 | 7.27 * 1.192 = 8.67 | 11.20 * 1.192 = 13.35 | 44.11 * 1.192 = 52.58 | 3 |

Values shown for Census tract 36001001400
Estimated person miles traveled from model using LATCH estimates and ACS data (Table 10) = 23.61
Estimated person miles traveled from model using NHTS and ACS data (Table 6) = 28.16
Difference in estimated person miles traveled = (28.16 – 23.61) / 23.61 = 19.2 percent
Difference calculated for each Census tract and used to transfer Census region/division estimate for each household type to the Census tract.
