| 摘要 |
The present application relates to a traffic calming surface, the upper surface of which has a continuous, substantially sinusoidal, profile which extends along the intended direction of travel. An advantage of traffic calming surfaces according to embodiments of the present invention is that they have been shown to generate significant interior noise and vibration which will act as a warning to the driver that he should reduce his speed. Trials have also shown that exterior noise disturbance, caused by vehicles traversing the surface, is substantially reduced as compared to the exterior noise arising from conventional rumble strip designs. |
