The objective of this research project is to develop near-future typed adhoc networking technology for vehicles and mobile users without any base stations and information centers. In restricted area with almost 1 Km by 1 Km squared, we have pursued to realize advanced adhoc networking systems that enable vehicles, pedestrians, and PC mobile users in the area to communicate each other tightly and get some real-time hot information. We have proposed a new communications system named Contents-Oriented Communication (COC). In this system, any one can get their necessary information urgently whether they do not know where such information is or what kind information and/or ID the information is. We have developed the algorithms for that system, and verified the validity of the proposed systems by computer simulations and various experiments with three vehicles.As results of the researches we have had the following.1) We have developed VACSS (Vehicular Collision Avoidance Support System) by getting the location information of vehicles and exchanging those with each other.2) We have developed VPEC (Vehicle PEdestrian Communications) to enable some small pedestrian terminal to communicate with nearby vehicles directly.3) We have developed the real time traffic estimation system by using COC.4) We have developed the real time situation recognition algorithms when some tragic accidents like Earth-quake, Fires, Terrorist' bombing, Massacre shooting and so on happen. We call this kind of systems, EUC (Emergency Urgent Communications).

本研究计画的目标是开发未来型的无基地台与资讯中心的车辆与移动的使用者自组网路技术。在近1公里乘1平方公里的限制区域，我们追求实现先进的adhoc网络系统，使该区域的车辆，行人和PC移动的用户能够紧密通信，并获得一些实时的热点信息。我们提出了一个新的通信系统命名为面向内容的通信（COC）。在该系统中，任何人都可以紧急获得他们所需的信息，无论他们是否知道这些信息在哪里或信息是什么类型和/或ID。我们已经开发了该系统的算法，通过计算机仿真和三辆车的各种实验，验证了所提出的系统的有效性，取得了以下研究成果：1）研制了VACSS通过获取车辆的位置信息并相互交换这些信息，开发了VPEC（Vehicle Pedestrian Communication），使小型行人终端能够直接与附近的车辆进行通信。3）利用COC开发了真实的时间交通估计系统。4）开发了地震、火灾、恐怖爆炸等悲惨事故时的真实的时间态势识别算法，大屠杀、枪击等事件时有发生。我们称这种系统为EUC（Emergency Urgent Communications）。
