Development of Bicycling Simulator for Evaluation of Traffic Safety in Bicycle Facilities

为了弄清骑行特征，我们首先进行了视频调查。其次，为了开发高质量的模拟器，我们揭示了需要骑车人在直行、左转或右转、启动和停止时的踏板、操纵、刹车和机动性的数据来模拟它们之间的关系。利用自行车和骑车人的行为模型，对自行车和骑车人的行为进行了建模，开发了仿真器的跟随规范和优点，并验证了自行车在骑行过程中的倾斜、刹车和骑手的位置特征。其特点是：1)可以使用头盔显示器在宽视角下直观地识别周围的情况；2)自行车上的自行车可以很容易地互换，并在实验中使用受试者自己的自行车；3)作为便携式模拟器，不仅可以在日本实验，而且可以在世界各地进行实验。

To clarify the bicycling characteristics, at first, we conducted the video survey. Secondly, for developing the simulator with high-quality, we revealed that we need the data of pedalling, handling, braking and mobility the center of riders' gravity in going straight, turning left or right, starting, and stopping from single bicycle riding to model the relationship between them. We modelled the bicycles' and riders' behavior and developed the simulator following specification and advantages using the bicycles' and riders' behavior model, and validated the characteristics of leaning, breaking and riders' position during cycling. The features are; 1) to be possible to visibly recognize the surround situation in the wide sight angles using the head-mounted display, 2) to be easily-interchangeable of bicycle on it and use the subjects' own bicycles in the experiments, and 3) to be a portable simulator and be not able to experiment only in Japan but also all over the world.
