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.

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。卡车流量增长过快，电动自行车的普及（2016年销售量：560，000件）增加，吸引老年人重新骑自行车。为了正确评价骑车人的安全性，特别需要研究不同车型、不同超车距离和不同车速时骑车人所受的压力和吸力，但目前对这方面的科学认识还很缺乏。并且不可能估计使骑自行车者能够安全地补偿由超车过程引起的干扰所需的自行车道的宽度。计划进行实验场和实验室测试，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，根据这些结果，应开发确定性模型，用于确定连续自行车车道宽度。
