摘要
交通动态信息图形化发布是通过对道路网抽象简化形成简易道路图形,并在此基础上发布实时路况的交通信息发布方式。在移动终端上发布图形化动态信息时,应充分考虑移动终端的可移动性以及实时在线特性,在关键的位置发布合理的图形信息,才可提高交通动态信息的识别度和提升信息诱导效果。通过分析驾驶人信息接收过程和线路的调整行为特性,研究图形化数据受信距离的设置方法,建立受信距离计算模型,给出了模型关键参数的计算方法和参考数据,从而为后期规模性图形化发布位置的布设奠定基础。
Dynamic traffic information graphical publication provides simple road graph by simplifying original road network, and publishes real-time traffic status. It is necessary to consider about the mobility and the real-time on line characteristic of the mobile terminal, and publish reasonable graphic information at the key place, with all of this the reliability and inductive effect of dynamic traffic information could be increased. Through analyse the behavioral characteristic of drivers during massage receiving and to adjust the way, research the setting method of graphical data message receive distance, the calculation model is built. The paper gives the calculation method and reference data of the key parameters of the model, in order to lay the foundation for the arrangement of scale of graphical publication in the future.
