我们已经开发了一种专用的车载“传感器”，利用无线通信设备在道路交叉口周围避免碰撞。传感器通过比较安装在观察车辆四个角落的四个ZigBee接收器接收信号的强度来估计交通参与者身上发射器的位置。在我们以前的工作中，“传感器”被提出作为交叉口周围避碰的替代工具。在此，我们通过考虑路面反射模型来扩展我们以前的工作，以提高估计精度。通过使用该模型，我们成功地减少了估计算法中观测数据和校准数据之间的误差失配。通过FDTD电磁波传播仿真，验证了反射模型的有效性。拟议的系统将在这些改进的基础上实现。
We have developed a dedicated onboard “sensor” utilizing wireless communication devices for collision avoidance around road intersections. The “sensor” estimates the positions of transmitters on traffic participants by comparing the strengths of signals received by four ZigBee receivers installed at the four corners of observing vehicle. In our previous work, the “sensor” was proposed as an alternative tool for collision avoidance around intersections. Herein, we extend our previous work by considering a road surface reflection model to improve the estimation accuracy. By using this model, we succeeded in reducing the error mismatches between the observed data and the calibration data of the estimation algorithm. The validity of the reflection model is verified via FDTD electro-magnetic wave propagating simulation. The proposed system will be realized on the basis of these enhancements.
