In the official truck platooning tests, three trucks with the back two unmanned successfully ran at a speed of 80 km/h with vehicular gap of 9 m. When multiple trucks move on a bridge at a certain distance between vehicles, large bridge vibration occurs due to the coupled vibration of the vehicles and the bridge. In the case of continuous bridges, there are many vibration frequencies of multiple bridges in close range. Consequently, it is expected that a lot of coupled vibrations between trucks and bridges will be generated. Therefore, this study examined how bridge vibration changes when the vehicular gap is varied through truck platooning tests and vehicle running simulations.
