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，本研究开发了在共享人行道上对行人和自行车分离产生影响的路面装置。本研究得出以下几点结论。1)通过对德岛市和高松市各类街道路面振动特性的分析，自行车和轮椅的感官评价受到4Hz ~ 15Hz振动的影响。2)建议采用梯形截面的驼峰装置，使自行车在4-15Hz左右产生不愉快的振动，而轮椅的速度约为自行车的四分之一，使用者不会感到振动。行人、骑自行车者和轮椅使用者使用长20米、间隔设置硬橡胶驼峰的测试街道进行感官检测，发现间隔50厘米的50cm宽、1cm高的驼峰具有适当的特性。3)提出了自行车驼峰的目的类型，即在自行车道或轨道上控制自行车的速度，在交叉口前唤醒自行车的注意力，在共享空间上分隔行人和自行车。从自行车和轮椅的实验中分析了最适合这些目的的形状。4)混凝土块和两种液体相关树脂作为实际使用的自行车车座材料，通过在德岛大学的路面上制作，并检查振动特性。检查滑动阻力，对行走感。结果表明，这些材料的特性与橡胶型驼峰实验结果一致。在路面上进行试验，考察实际使用中的效果和存在的问题，是今后研究的必要条件。

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.
