【摘要】：随着城镇化速度的加快,中小城市交通问题日益突出。由于中小城市交通道路资源有限,如何充分利用现有交通资源,提高道路的利用率,以最小的投入最大程度地改善中小城市交通拥堵状态成为当前研究的热点,智能交通系统在此背景下应运而生。本文研究的海宁市在使用智能交通解决城市道路拥堵方面取得了一定的效果,但仍然存在如下问题:交通诱导信息发布滞后;交通诱导信息发布形式单一;交通诱导信息发布后无反馈。针对这些问题,本文为该城市设计了有针对性的交通诱导信息发布平台,可在一定程度上缓解该城市的交通拥堵状态,进而为其他中小城市的交通管理提供相关经验。论文主要工作如下:(1)通过改变传统交通诱导信息发布的流程,在数据预处理之后,加入基于SVR-IGA的交通流预测算法,通过该算法提前感知路段的交通状态,对可能发生的交通拥堵状态进行预警,解决了交通诱导信息发布滞后方面的问题。(2)通过建立中小城市交通诱导信息发布平台,实现了交通诱导信息多样性发布,解决了该城市交通诱导信息发布形式单一方面的问题。(3)提出了基于事件驱动的状态反馈,通过对诱导屏及摄像机定位、摄像机实时视频的显示、远程访问中小城市交通诱导信息发布平台三个功能的研究,最终完成了事件驱动的信息发布状态反馈研究内容,解决了交通诱导信息发布后无反馈方面的问题。
[Abstract]:With the acceleration of urbanization, the traffic problems in small and medium-sized cities are becoming more and more prominent. Due to the limited traffic road resources in small and medium-sized cities, how to make full use of the existing traffic resources, improve the utilization rate of roads, and improve the traffic congestion in small and medium-sized cities to the greatest extent with minimum investment has become the focus of current research. Intelligent transportation system emerges as the times require under this background. Haining City studied in this paper has achieved some results in using intelligent transportation to solve urban road congestion, but there are still the following problems: traffic guidance information release lag, traffic guidance information release form is single; There is no feedback after the release of traffic guidance information. In order to solve these problems, this paper designs a targeted traffic guidance information publishing platform for the city, which can alleviate the traffic congestion of the city to a certain extent, and then provide relevant experience for the traffic management of other small and medium-sized cities. The main work of this paper is as follows: (1) by changing the process of traditional traffic guidance information release, after data preprocessing, the traffic flow prediction algorithm based on SVR-IGA is added, through which the traffic state of the road section is sensed in advance. The problem of lagging traffic guidance information release is solved by warning the possible traffic congestion state. (2) by establishing the traffic guidance information publishing platform in small and medium-sized cities, the traffic guidance information diversity release is realized. The problem of single form of traffic guidance information release in this city is solved. (3) an event-driven state feedback is proposed, through the positioning of the induction screen and camera, and the display of real-time video of the camera. The research on the three functions of remote access to traffic guidance information publishing platform in small and medium-sized cities is carried out. Finally, the event-driven information publishing state feedback research content is completed, and the problem of no feedback after traffic guidance information release is solved.
