Vehicular communication systems (VCS) are an emerging information and communication technology aimed to improve road safety, support intelligent transportation, and provide infotainment services to users on roads. Various R&D activities around the globe have been carrying out in recent years for the technology development. This research project is to investigate and develop novel engineering solutions for efficiently providing various vehicular communication services, especially for high-rate large-volume data transfer in in-vehicle Internet access, by taking advantage of heterogeneous wireless networking technologies including cellular networks, WiFi, and the dedicated short-range communications (DSRC). In particular, this project will develop (i) an intelligent data traffic offloading scheme from cellular networks to WiFi/DSRC networks, (ii) an inter-working framework between cellular networks and WiFi/DSRC networks for seamless service delivery in VCS, and (iii) dynamic access on available TV radio spectrum for data transfer in a vehicular environment, making use of the property that vehicle movement trajectories are limited to road geometry.

车辆通信系统（VC）是一种新兴的信息和通信技术，旨在提高道路安全，支持智能运输并为道路上的用户提供信息娱乐服务。近年来，全球各种研发活动一直在开展技术开发。该研究项目是通过利用异构的无线网络技术，包括蜂窝网络，WiFi，Wifi，WiFi，，调查和开发新型的工程解决方案，以有效地提供各种车辆通信服务，尤其是用于高速公路内互联网访问的大型大容量数据传输。以及专用的短期通信（DSRC）。特别是，该项目将开发（i）一个智能数据流量从蜂窝网络到WiFi/DSRC网络，（ii）蜂窝网络与WIFI/DSRC网络之间的工程间框架，用于VC中的无缝服务，以及（ iii）在可用的电视无线电频谱上进行动态访问，以在车辆环境中进行数据传输，利用车辆移动轨迹仅限于道路几何形状的属性。
