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.
