Ride comfort is one of the key issues in passenger transport. Its level depends on many factors related to both environmental factors and individual human characteristics. Ensuring good travel conditions translates into higher quality transport services. This article presents a literature review, which shows that ride comfort is most often considered in the context of the impact of mechanical vibrations on the human body, while other factors are usually neglected. The aim of this study was to conduct experimental studies that take into account more than one type of ride comfort. These studies concerned metro cars in the Warsaw metro system. Three types of comfort were evaluated: vibrational, thermal, and visual, based on vibration acceleration measurements, air temperature, relative air humidity, and illuminance. The ride comfort in the vehicle bodies' front, middle, and rear parts was tested under typical running conditions. The criteria for assessing the effect of individual physical factors on ride comfort were selected based on applicable European and international standards. The test results indicate good thermal and light environment conditions in every measuring point. The slight decrease in passenger comfort is undoubtedly due to the effects of vibrations occurring while mid journey. In tested metro cars, horizontal components have a more significant impact on reducing vibration comfort than other components.
乘坐舒适性是客运中的关键问题之一。其水平取决于许多与环境因素和个人特征相关的因素。确保良好的旅行条件意味着更高质量的运输服务。本文进行了文献综述，结果表明，乘坐舒适性大多是在机械振动对人体影响的背景下被考虑的，而其他因素通常被忽视。本研究的目的是进行考虑多种乘坐舒适性类型的实验研究。这些研究针对华沙地铁系统中的地铁车厢。基于振动加速度测量、空气温度、相对空气湿度和照度，评估了三种类型的舒适性：振动舒适性、热舒适性和视觉舒适性。在典型运行条件下测试了车厢前部、中部和后部的乘坐舒适性。根据适用的欧洲和国际标准选择了评估各个物理因素对乘坐舒适性影响的标准。测试结果表明每个测量点的热环境和光照环境条件良好。乘客舒适性的轻微下降无疑是由于行程中出现的振动影响。在测试的地铁车厢中，水平分量对降低振动舒适性的影响比其他分量更大。
