在美国各地，共享使用路径正变得越来越繁忙。路径设计者需要关于创建新的或重建的路径的宽度以及是否区分不同类型的用户的指导。目前的指导不是具体的，没有根据美国的情况进行校准，也没有适应典型路径上的模式范围。这个由FHWA赞助的项目的目的是开发一种针对共享使用路径的服务级别(LOS)评估方法，以克服这些限制。本文的重点是收集路径用户的感知，并建立一个将这些感知与操作变量和路径变量联系起来的模型。配套论文描述了为建立解释路径操作的方程和开发基于感知模型的视距估计工具所做的努力。在这项工作中，项目组收集了105名志愿者观看来自10条路径的36个视频片段的感受。分析表明，与路径操作和路径宽度相关的变量与路径体验的整体质量的关系最强。推荐的总体评级模型包括路径宽度、会议和路过事件的数量以及中心线的存在。该模型在统计学上是可靠的；它应该很容易使用。分析员应该能够信心十足地使用该模型和基于该模型的确定LOS的程序，因为他们知道该模型基于大量TRAIL用户的感知。
Shared-use paths are becoming increasingly busy across the United States. Path designers need guidance on how wide to make new or rebuilt paths and on whether to separate the different types of users. The current guidance is not specific, has not been calibrated to conditions in the United States, and does not accommodate the range of modes found on a typical path. The purpose of this project, sponsored by FHWA, was to develop a level-of-service (LOS) estimation method for shared-use paths that overcomes these limitations. The focus of this paper is on the collection of the perceptions of path users and the development of a model relating those perceptions to operational and path variables. Companion papers describe the efforts made to develop equations explaining path operations and to develop an LOS estimation tool based on the perception model. For this effort, the project team collected the perceptions of 105 volunteers viewing 36 video clips from 10 paths. Analysis showed that variables related to path operations and the path width had the strongest relationships to the overall quality of the trail experience. The recommended model for overall rating included terms for path width, the number of meeting and passing events, and the presence of a centerline. The model was statistically sound; it should be easy to use. Analysts should be able to use the model and the procedure for determination of the LOS, which is based on the model, with confidence, knowing that it is well grounded on the perceptions of a large sample of trail users.
