EAGER: Improving Pedestrian Safety Using Pervious Concrete to Reduce Slip-Related Falls

“这项奖励是根据2009年美国复苏和再投资法案（公法111-5）资助的。”本项目的研究目的是评估在正常和恶劣天气条件下，在透水混凝土路面上与传统混凝土路面相比，行人安全行走的生物力学。这种路面的高渗透性使融化的冰雪不太可能再次冻结并形成表面冰。较少的地表水，加上其开放的表面纹理，可能会在不利的冬季条件下形成更安全的路面。滑倒和跌倒对实际和感知的行动能力都是一个问题，特别是在老年人中。建议工作的目的是确定透水混凝土路面？与传统的防渗路面相比，对防摔的影响更大。具体目标包括：1。测定透水混凝土的材料表面性能，并与传统混凝土进行比较。2. 量化与在透水混凝土上行走相关的生物力学，并与在干燥和结冰条件下在传统混凝土上行走的生物力学进行比较。透水混凝土有可能改善牵引力，减少在不利条件下滑动和坠落的情况。创造一个更安全的行走表面可以降低医疗和保险成本，同时保持老年人的行动能力和独立性。表征透水混凝土表面的运动并与传统混凝土进行比较，将有助于识别路面表面与滑移相关的重要属性。

"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."The research objective of this project is to evaluate pedestrian biomechanics of safely walking on pervious concrete, compared to traditional concrete pavement, in normal and adverse weather conditions. The high permeability of this pavement makes melting snow and ice much less likely to refreeze and form surface ice. Less surface water, coupled with its open surface texture, may result in a much safer pavement under adverse winter conditions. Slipping and falling is a concern both for actual and perceived mobility, particularly among older adults. The objective of the proposed work is to determine pervious concrete pavement?s impact on fall protection as compared to traditional impervious pavement. The specific aims include: 1. Measure the material surface properties of pervious concrete and compare with those of traditional concrete. 2. Quantify the biomechanics associated with walking on pervious concrete and compare with those of walking on traditional concrete in both dry and icy conditions.Pervious concrete has the potential to improve traction and reduce instances of slipping and falling under adverse conditions. Creating a safer walking surface may decrease medical and insurance costs, while maintaining the mobility and independence of older adults. Characterizing movement on pervious concrete surfaces and comparing with traditional concrete will help identify important slipping-related attributes of the pavement surfaces.
