Three travel cost models are used to estimate non-fishing recreation demand at the Snake River reservoirs recreation area in eastern Washington. The opportunity cost of time is specified in the "traditional" and McConnell-Strand models as a fraction of the exogenous market wage rate and in the two-step decision model as a function of socioeconomic attributes of the recreationists. Benefits per person per trip were $90, $35, and $46 respectively, for the three models. Boaters visit the site more than three times as often as non-boaters resulting in higher annual benefits for boaters.
三种旅行成本模型被用于估计华盛顿东部斯内克河水库休闲区的非捕鱼娱乐需求。在“传统”模型和麦康奈尔-斯特兰德模型中，时间的机会成本被指定为外生市场工资率的一部分，而在两步决策模型中，它则是休闲者社会经济特征的函数。对于三种模型，每人每次旅行的收益分别为 90 美元、35 美元和 46 美元。与非划船者相比，划船者到该地点的访问频率高出三倍以上，从而使划船者获得更高的年度收益。
