In response to federal administrative rule, the Tahoe National Forest (TNF), California, USA engaged in trail-route prioritization for motorized recreation (e.g., off-highway-vehicles) and other recreation types. The prioritization was intended to identify routes that were suitable and ill-suited for maintenance in a transportation system. A recreational user survey was conducted online (n = 813) for user preferences for trail system characteristics, recreational use patterns, and demographics. Motorized trail users and non-motorized users displayed very clear and contrasting preferences for the same system. As has been found by previous investigators, non-motorized users expressed antagonism to motorized use on the same recreational travel system, whereas motorized users either supported multiple-use routes or dismissed non-motorized recreationists' concerns. To help the TNF plan for reduced conflict, a geographic information system (GIS) based modeling approach was used to identify recreational opportunities and potential environmental impacts of all travel routes. This GIS-based approach was based on an expert-derived rule set. The rules addressed particular environmental and recreation concerns in the TNF. Route segments were identified that could be incorporated into minimal-impact networks to support various types of recreation. The combination of potential impacts and user-benefits supported an optimization approach for an appropriate recreational travel network to minimize environmental impacts and user-conflicts in a multi-purpose system.
针对联邦行政规定，美国加利福尼亚太浩国家森林（TNF）对机动车娱乐（如越野车）和其他娱乐类型的路线进行了优先级排序。这种优先级排序旨在确定适合和不适合交通系统维护的路线。TNF 进行了一项在线休闲用户调查（n = 813），以了解用户对步道系统特征、休闲使用模式和人口统计数据的偏好。机动车步道用户和非机动车用户对同一系统表现出非常清晰和截然不同的偏好。正如先前的研究人员发现的那样，非机动车用户对同一娱乐旅行系统中的机动车使用表示反感，而机动车用户要么支持多用途路线，要么对非机动车休闲者的担忧不屑一顾。为了帮助 TNF 减少冲突，该机构使用基于地理信息系统（GIS）的建模方法来识别所有旅行路线的休闲机会和潜在环境影响。这种基于 GIS 的方法基于一套专家制定的规则。这些规则解决了 TNF 中的特定环境和娱乐问题。确定了可以纳入低影响网络的路线段，以支持各种类型的娱乐活动。潜在影响和用户效益的结合支持了一种优化方法，以建立一个适当的娱乐旅行网络，在多用途系统中最小化环境影响和用户冲突。
