【摘要】 面向出行者的出行诱导系统研究与设计考虑到为出行者出行提供一条方便快捷的出行路线,并以尽可能减少时间、距离和费用等代价为目的,为出行者根据自己的需求规划出出行路线,并反馈给出行者。论文首先对交通参数基本概念进行了介绍,并把传感器采集到的流量、速度和占有率数据进行了分析处理,绘制出了一周内交通流的变化趋势,得出了每天的交通高峰期时间段。接着在交通数据分析的基础上,结合历史交通数据和传感器采集到的数据通过卡尔曼滤波器对不同路段的流量、速度和占有率进行了短时预测,得出不同时间的路段的交通拥堵情况。然后,出行诱导系统对公交和自驾车出行进行了不同方式的诱导,实现了公交换乘和动态路径规划。公交换乘提出了“换乘最少”的算法,并提出了时间、距离、最少站点等换乘评价模型,设计实现了公交换乘系统。路径规划系统建立了行程时间预测模型,为自驾车出行提供了多种出行方式,结合实时路径信息,实现了动态路径规划。最后,研究了交通通信息多种发布方式中的语音的发布方式,给出了Microsoft Speech SDK语音引擎接口的实现以及语音发布系统的总体设计、功能和具体实现。出行线路诱导系统是交通信息服务中的重要组成部分,对出行者的出行决策进行诱导,将使出行者选择最优的出行路线,避开交通拥堵路段,使得道路网资源得到高效充分利用,节约了出行时间,并缓解了交通堵塞以及由此引发的环境恶化、交通安全问题和社会问题。更多还原

【Abstract】 Research and design of the traveler-oriented guidance system considers providing a convenient and quick route which has the lowest cost of time, distance or charge for travelers, and plans a route for travelers in accordance with their requires. And the required information will be feedback to them.First, this essay introduces the basic traffic parameters, analyses the volume, speed and occupancy data collected by sensors, plots the traffic trends in a week, and gets the time periods which are the highest traffic peaks one day. Next, based on the traffic data analysis, volume, speed and occupancy of the different roads, combined with the historical data and real-time data collected by sensors, are predicted by kalman filter to get the traffic states of the road in different time in a day. Further, guidance system provides separate guidance methods for traveling by bus and by car and completes bus transfer system and dynamic route planning system. Public traffic transfer system realizes the transfer algorithm with the view of minimum transfer times, and gives the time, distance and minimum bus stations evaluation model. Dynamic route planning system creates dynamic traveling time prediction model. Combined with the real-time traffic information, dynamic route planning system is completed. At last, voice release manner of kinds of traffic information release manners is researched. Microsoft Speech SDK speech engine interface is given as well as structure, function and specific realization of voice release system.Traveling line guidance system is an important part of the ATIS system. It can guide the travelers’ choice, make the travelers chose the optimal route,avoid the traffic jam, make full use of the current road resources, raise the efficiency of the current traffic transport system, and relieve the environmental and social problems caused by traffic jams.更多还原
