In this study, we set up a virtual subway car and analyzed the stress response of young passengers in different compartments. A total of 10 volunteers participated in the experimental study. We measured their diastolic blood pressures, systolic blood pressures, and heart rates, from a car density of one person per square meter to a density of 10 persons per square meter, using 37° sport wristbands. The results show that the participants’ mean, minimum, and maximum heart rates were within the normal range, but the ratio of their mean to their maximum heart rate was 73.69%, a level that would have an impact on human health. Their mean, minimum, and maximum diastolic blood pressures and systolic blood pressures were within the normal range. Passenger density had no significant effect on diastolic blood pressure, systolic blood pressure, or heart rate (p < 0.05). Diastolic and systolic blood pressures were significantly positively correlated, whereas diastolic blood pressure and heart rate, and systolic blood pressure and heart rate, were negatively correlated, although not significantly. For the sake of comfort, we recommend five persons per square meter as the critical value of congestion.

在这项研究中，我们建立了虚拟地铁车厢，并分析了不同车厢中年轻乘客的压力反应。共有10名志愿者参加了实验研究。我们使用37°运动腕带测量了他们的舒张压，收缩压和心率，从每平方米一人的汽车密度到每平方米10人的汽车密度。结果表明，参与者的平均，最小和最大心率均在正常范围内，但其平均心率与最大心率之比为73.69％，该水平会对人体健康产生影响。他们的平均，最小和最大舒张压和收缩压均在正常范围内。乘客密度对舒张压，收缩压，p  ＜0.05）。舒张压和收缩压呈显着正相关，而舒张压和心率与收缩压和心率呈负相关，尽管不显着。为了舒适起见，我们建议每平方米五个人作为拥堵的临界值。
