Improvement methods of shared use sidewalks for bicycles and pedestrians by using devices on road surface

在关注行人、骑自行车者和轮椅使用者对路面振动偏好差异的基础上，本研究开发了影响共享人行道上行人和自行车分隔的路面装置。1)通过对德岛市和高松市各类街道路面振动特性的分析，得出了自行车和轮椅在4~15赫兹范围内受振动影响的感官评价。2)提出了一种梯形段驼峰装置，使自行车在4~15赫兹范围内产生不愉快的振动，而轮椅使用者在速度约为自行车的1/4时不会感觉到振动。通过对行人、骑自行车者和轮椅使用者在设置硬质橡胶驼峰的20m长的试验街道上的感知检查，发现50 cm宽、1 cm高的50 cm间隔驼峰具有合适的特征。3)提出自行车驼峰的用途类型，即在自行车专用道或轨道上控制自行车的速度，在路口前唤醒自行车，在共享使用空间上实现人车分开。通过自行车和轮椅的实验，分析了最适合这些用途的形状。4)通过在德岛大学的路面上制作混凝土块和两种与液体有关的树脂作为实际使用的自行车驼峰材料，并检查振动特性。检查滑动阻力，行走感觉。试验结果表明，这些材料的性能与橡胶驼峰试验基本一致，在路面上进行试验，检验其在实际应用中的效果和存在的问题，为今后的研究奠定了基础。

On the basis of focus on a difference of preference to the road surface vibration of pedestrians, cyclists, and wheelchair users, this study developed pavement devices that had an effect on the separation of pedestrians and bicycles on the shared use sidewalks. In this study, the following points are concluded.1) By the analysis of vibration characteristic by road surface on various kinds of streets in Tokushima city and Takamatsu city, sense evaluation of bicycles and wheelchairs is affected by vibration from 4Hz to 15Hz.2) A hump device of a trapezoid section is proposed so that bicycle would have unpleasant vibration around 4-15Hz, but wheelchair uses would not feel vibration as the speed is about one-fourth of bicycles. As a result of examination of sense by pedestrians, cyclists and wheelchair users using test street of 20m long which is installed hard rubber humps at some intervals, it was found that humps of 50cm width and 1cm height located at 50cm interval has appropriate characteristics.3) Purpose types of bicycle hump are proposed, that is bicycle speed control on cycling lane or tracks, awake bicycles' attention before intersections, and separation of pedestrian and bicycles on the shared use space. Most suitable shapes for these purposes are analyzed from the experiment of bicycles and wheel-chairs.4) Concrete blocks and two liquid-related resin are examined as materials of bicycle humps for practical use, by making on a pavement in University of Tokushima and check the characteristics of vibration. inspection of sliding resistance, sense on walking. It showed the characteristic of these materials are expected same as the rubber type hump experiments.Experiments on the pavement to inspect effects and problems in practical use is necessary for the future research.
