在模拟东京湾水上大桥的大梁上，对车辆进行了不同车道、车辆类型、相对角度和气流情况下的风洞试验。计算了作用在飞行器上的压力分布和气动力系数。结果表明，不同车道、不同车型、不同相对角度、不同气流的压力分布和气动系数差异较大。因此，有可能根据车辆类型和车道，采用合理的交通管制标准，而不是现行的不考虑差异的交通管制标准。
In this study, wind tunnel tests were conducted on vehicles on a girder simulating the Tokyo Bay Aqua Bridge for various cases of lane, vehicle type, relative angle, and airflow. The pressure distribution and aerodynamic force coefficient acting on the vehicles were calculated. As a result, the differences in the pressure distribution and aerodynamic coefficients according to the lane, vehicle type, relative angle, and airflow were significant. Therefore, it indicates the possibility of applying reasonable traffic regulation standards depending on vehicle type and lane instead of the current regulation standards where no differences are considered.
