- Abstract
- This study focuses in the impact of vehicle speed, vehicle type, and transverse rumble strip (TRS) design on the sound pressure level perceived by drivers when they traverse a TRS. TRSs are commonly installed on approaches to toll plazas and at intersections, etc. The ability of a TRS to capture a driver's attention is directly related to the magnitude of the sound and vibration. However, the traffic noise generated by TRS creates a problem for adjacent residences and businesses near the roadway. Thus, the aim of this study is to quantify the level of traffic noise and verify the effects of TRS shapes. The research team measured the exterior noise, inner noise, and vibration generated by three types of vehicles (sedan, minivan, and truck) traveling over four types of transverse rumble strip applications (Types A, B, C, and D) with speed range between 40 and 100 km/h. In general, the increase in the exterior noise generated was greater at 100 km/h than at 40 km/h and lower for a sedan than for a truck. Type A generated the highest exterior noise and Type C generated the highest inner noise. The sound level clearly changed according to TRS dimension such as shape, width, and length, etc. Type C showed the best performance with a lower sound pressure level, effective ability to alert the driver, and reduced complaints from adjacent residents after implementation on a highway road in Korea.
