The estimated values of  and the t-statistics with respect to the null hypothesis of =1 (note that standard discrete choice models assume =1) are presented in Table 4. The table indicates the following results. First, all the satiation parameters are very significantly different from 1, thereby rejecting the linear utility structure employed in standard discrete choice models. That is, there are clear satiation effects in vehicle holdings and usage decisions. Second, as expected, middle and high income households are more likely to get satiated with the increasing use of any vehicle type/vintage compared to low income households. That is, middle and high income households are more likely to own and use multiple types/vintages of vehicles. Third, low income households are least likely to get satiated with the increasing use of old subcompact sedans, new and old compact sedans, and old midsize sedans, presumably because these vehicle type/vintage categories efficiently satisfy the functional needs of such households. Finally, the satiation effect is highest for non-motorized mode of transportation compared to all vehicle type/vintage categories. This is to be expected since the annual miles of walking and bicycling is very small relative to the use of motorized vehicles.
