摘要： 提出了利用混合无线光纤宽带接入网(hybrid WirelessOptical BroadbandAccess Network,简记为WOBAN)把宽带业务延伸至车辆的新思路，给出了一个城市道路的工作模型.考虑到车流量是影响光网络单元，即ONU有效安置的关键因素，特别设计了一个基于流量的城市道路特征抽取机制，区分出四类不同的考察点.在此基础上，提出并比较了两种ONU位置评价策略.

Abstract: A new idea to bring broadband service to vehicles by WOBAN (hybrid WirelessOptical BroadbandAccess Network) was presented and a working model of an urban road WOBAN was given. Considering traffic flow as a key factor for the optimal ONU (Optical Network Unit) placement in urban road WOBAN, a scheme to characterize urban road features based on traffic flow was proposed and four examined spot types were defined. Furthermore, we compared two place evaluation strategies. 
