    Evaluation, monitoring and comparison of traffic safety in various territories presents a major challenge to the traffic safety researches. Vibration is a natural phenomenon that can occur in a various medium such as ground, air, and water produced by a movement of living or non-living thing. Vehicle is one of the factors that can cause vibration to the ground whether it is moving or at rest. The vibration sometimes can be a nuisance for certain time by giving negative effects to the receiving things. Effect of the vibration can also make local residents nearby a speed hump feel uncomfortable and annoyed with the vibration produced when a heavy vehicle passing over the speed hump. Therefore, to address this problem, following objectives have been developed: - 1) To investigate the relationship between the type of a vehicle and the ground vibration generated by the vehicle that goes through the speed hump. 2) To analyse the effect of vehicle speed and the ground vibration produced when the vehicle passing through the speed hump. The method used to perform this study is vibration monitoring method by using ICP accelerometer and data acquisition unit and also DEWEsoft X3 to interpret peak particle velocity for each data. LiDAR speed gun was used to observe the speed of a vehicle passing over the speed hump. From the total of twelve data, results indicate the highest peak particle velocity reading for the vibration is at 0.69 mm/s produced by the largest vehicle and the lowest is 0.36 mm/s produced by the slowest vehicle when it passed over the speed hump. As conclusion, the higher the speed of a vehicle passing over the speed hump the higher peak particle velocity produced and the type of a vehicle will produce different peak particle velocity depends on the weight of a vehicle.
