Study on a method for traffic risk detection and notification with inter-vehicle communication and designing its testbed for evaluation

在这项研究中，我们设计和评估系统的交通安全。首先，我们提出了一种方法定位的行人与定向天线和车辆间的通信，我们已经证实，与多辆车的定位达到更高的精度比一辆车。接下来，我们提出了一个消息路由协议，在车辆自组织网络中使用的规划路线的每辆车，我们已经证实，该协议可以广泛提高消息的交付率，减少消息开销。最后，我们开发了一个交叉口鸟瞰复合系统，使用车载摄像头的每辆车和车辆间的通信和测试平台，用于评估系统。

In this study, we have designed and evaluated systems for traffic safety. First, we have proposed a method for localization of pedestrians with directional antennas and inter-vehicle communication, and we have confirmed that the localization with multiple vehicles achieves higher accuracy than that with one vehicle. Next, we have proposed a message routing protocol in a vehicular ad hoc network using the planned route of each vehicle, and we have confirmed that the protocol can widely improve the message delivery ratio and reduce message overhead. Finally, we have developed an intersection-bird-view composite system using the on-board camera of each vehicle and inter-vehicle communication and a testbed for evaluating the system.
