Abstract(J) | 交差点付近での音波の伝搬を差分法によって予測計算した.その結果,交差点の幾何学的な配置,障害物の音響特性,車両の位置などの車両間の音波の伝搬への影響が定量的に明らかになり,車両に搭載するマイクロホンへの入力信号の時間的変化も計算ができ,検知システム開発の基礎ツールができた. Translation |
Abstract(E) | To reduce the number serious accidents, it will be effective to detect vehicles outside the field of view by sound. Its detection ability has already been confirmed in experiments at several intersections. In this study, we calculated the propagation of sound waves near an intersection by finite difference method. As a result, the influences of the geometrical arrangement and acoustical properties of intersections, the relative position of the vehicles near the intersection on the sound propagation were quantitatively identified. This analysis will be able to accelerate the development of a system that detects out of the sight vehicles. |
