Wind forces generated by passing vehicles on cyclists and development of a model to determine the necessary width of bicycle lanes

越来越多的人使用自行车作为交通工具。与此同时，骑自行车的潜在危险也在增加。卡车运输量的过度增长和自行车的普及（2016年销量：56万辆）的增加，吸引了老年人重新骑自行车。为了能够正确地评估骑自行车的人的安全，特别有必要检查当骑自行车的人被不同类型的、不同距离和不同车速的车辆超过时，他所受到的压力和吸力。关于这一主题缺乏科学知识，而且不可能估计出自行车道的宽度，以使骑自行车的人能够安全地补偿超车过程所造成的干扰。计划进行实验现场和实验室测试，以测量超车过程中作用在骑车人身上的力，并在进一步的步骤中，基于这些结果，将开发一个确定所需自行车道宽度的确定性模型。

More and more people use the bicycle as a means of transport. At thesame time, the danger poten-tial for cyclists increases. Truck traffic isgrowing over-proportionally and the spread of pedelecs (sales number2016: 560,000 pieces) increases, luring the elderly back on theirbikes. In order to be able to assess the safety of cyclists correctly, it isnecessary, in particular, to examine the pressure and suction forceswhich act on the cyclist when he is overtaken by different vehicletypes with dif-ferent passing distances and different vehicle speeds.There is a lack of scientific knowledge on this topic, and it is notpossible to estimate the width of a bicycle lane required to enable acyclist to safe-ly compensate for the disturbance caused by theovertaking process. Experimental field and labora-tory tests areplanned to measure the forces acting on the cyclist during theovertaking process and, in a further step, based on these results, adeterministic model for the determination of the neces-sary bicyclelane width shall be developed.
