A study about universal design of sidewalk space in snow cold districts

根据2000年颁布的交通无障碍改善法，新的人行道设计指南已经发布。从那时起，倾斜、横坡、断层和人行道的均匀性成为日本的重要问题。为了检测使用者的这些障碍，评估人行道的可达性，需要方便、快速、准确地测量人行道的纵向和横向轮廓。日本最近开发了三台用于测量路面的便携式轮廓仪，因此我们尝试使用它们来测量人行道的轮廓。本文介绍了这些便携式轮廓仪的工作原理和从实测数据计算人行道轮廓的方法。它还讨论了使用现场测量数据的便携式分析器的准确性和可重复性。

A new guideline for sidewalk design has been published, based on the transportation accessibility improvement law legislated in 2000. Since then, incline, cross slope, faulting, and evenness of sidewalks have become important issues in Japan. To detect these barriers for users and to evaluate sidewalk accessibility, it is necessary to easily, rapidly and accurately measure the longitudinal and lateral profiles of the sidewalk. Three portable profilers for measurement of road surfaces have recently been developed in Japan, so we tried to use them for measurement of sidewalk profiles. This paper presents the mechanism of these portable profilers and the methodology for calculating sidewalk profiles from measured data. It also discusses the accuracy and repeatability of portable profilers using data obtained from on-site measurements.
