Walking is the most basic and sustainable mode of transportation, and many jurisdictions would like to see increased walking rates as a way of reducing congestion and emission levels and improving public health. In the United States, walking trips account for 10.5% of all trips undertaken. To increase this rate, additional research on what makes people feel more comfortable while walking is needed. Research on pedestrian quality of service (QOS) has sought to quantify the performance of the pedestrian facilities from a pedestrian’s perspective. However, the impact of pedestrian safety countermeasures on pedestrian QOS for roadway crossings is largely unknown. The objective of this study is to discern pedestrian QOS based on physiological measurements of pedestrians performing normal walking activities in different traffic contexts. The naturalistic walking study described in this paper recruited 15 pedestrians and asked each to wear an instrumented wristband and GPS recorder on all walking trips for one week. Surprisingly, the findings from the study showed no correlation between participants’ stress levels and individual crossing locations. Instead, stress was associated with roadway conditions. Higher levels of stress were generally associated with walking in proximity to collector and arterial streets and in areas with industrial and mixed (e.g., offices, retail, residential) land uses. Stress levels were tempered in lower-density residential land uses, as well as in forest, park, and university campus environments. The outcomes from this study can inform how planners design urban environments that reduce pedestrian stress levels to promote walkability.

步行是最基本和可持续的交通方式，许多司法管辖区希望将步行速度提高，以减少交通拥堵和排放水平并改善公共卫生。在美国，步行旅行占所有旅行的10.5％。为了提高这一速度，需要进一步研究使人们在行走时感到更舒适的事物。对行人服务质量（QOS）的研究试图从行人的角度量化行人设施的性能。然而，行人安全对策对行人过路处的行人QOS的影响在很大程度上尚不清楚。这项研究的目的是基于在不同交通情况下执行正常步行活动的行人的生理测量结果来识别行人的QOS。本文描述的自然主义步行研究招募了15名行人，并要求每位步行者在一周内的所有徒步旅行中佩戴仪表腕带和GPS记录仪。令人惊讶的是，研究结果表明参与者的压力水平与个人穿越位置之间没有相关性。相反，压力与道路状况有关。压力的增加通常与在集热区和主干道附近以及工业和混合（例如办公室，零售，住宅）土地用途的地区步行有关。在低密度住宅用地以及森林，公园和大学校园环境中，压力水平得到了缓解。这项研究的结果可以告诉规划人员如何设计城市环境，以减少行人压力水平，从而提高步行能力。
