1.1 本规程涵盖了纵向轮廓测量的数学处理，以产生轮椅通道粗糙度统计数据，称为轮椅通道粗糙指数（WPRI）。 1.2 这为计算和报告人行道和其他行人表面的道路粗糙度估计值提供了标准做法。 1.3 以国际单位制表示的数值应视为标准。括号中给出的英寸磅单位仅供参考。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 该实践提供了一种方法，用于使用纵向轮廓测量设备获得定义为粗糙度的表面性质的定量估计。 5.1.1 WPRI可以从能够捕获高分辨率（如 X1.1.2 )纵向剖面。 5.1.2 WPRI随着时间的推移是稳定的，因为真正的WPRI是基于真实纵向剖面的概念，而不是特定类型仪器的物理特性。 5.2 当同时测量多个行驶车轮轨道的轮廓时，MWPRI比单独车轮轨道的WPRI更好地测量轮椅通道表面粗糙度。 5.3 轮椅路径粗糙度数据可用于确定轮椅使用者所经历的振动暴露。（参见 图1 .) 图1 轮椅通道粗糙度指数和等级 注1: MWPRI量表与WPRI量表相同。 5.3.1 振动暴露与轮椅使用者的疼痛和受伤有关，行走表面的WPRI提供了量化轮椅使用者在行走该表面时将经历的振动暴露的能力。 4. , 5. 5.3.2 了解轮椅使用者在行驶表面上会经历的振动暴露，可以采取措施将其暴露降至最低，从而降低疼痛和受伤的可能性。

1.1 This practice covers the mathematical processing of longitudinal profile measurements to produce a wheelchair pathway roughness statistic called the Wheelchair Pathway Roughness Index (WPRI). 1.2 This provides a standard practice for computing and reporting an estimate of pathway roughness for sidewalks and other pedestrian surfaces. 1.3 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This practice provides a means for obtaining a quantitative estimate of a surface property defined as roughness using longitudinal profile measuring equipment. 5.1.1 The WPRI can be obtained from instruments which can capture high-resolution (described in X1.1.2 ) longitudinal profiles. 5.1.2 The WPRI is stable with time because true WPRI is based on the concept of a true longitudinal profile, rather than the physical properties of a particular type of instrument. 5.2 When profiles are measured simultaneously for multiple traveled wheel tracks, the MWPRI is a better measure of wheelchair pathway surface roughness than the WPRI for either individual wheel track. 5.3 Wheelchair pathway roughness data can be useful in determining the vibration exposure experienced by a wheelchair user. (See Fig. 1 .) FIG. 1 Wheelchair Pathway Roughness Index and Ratings Note 1: The MWPRI scale is identical to the WPRI scale. 5.3.1 Vibration exposure has been linked to pain and injuries in wheelchair users and the WPRI of traveled surfaces provides the ability to quantify the vibration exposure a wheelchair user will experience when traveling that surface. 4 , 5 5.3.2 Knowledge of the vibration exposure a wheelchair user will experience on traveled surfaces will allow steps to be taken to minimize their exposure, reducing the likelihood of pain and injury.
