【摘要】：目前，我国高速公路的管理明显滞后于高速公路的建设，造成了高速公路速度并不高的现状，而且这已经成为很多道路使用者的共同感受；交通事故时有发生，造成巨大的生命财产损失。这些问题的严重性已经逐渐在我国高速公路的建设和管理过程中凸显出来，政府管理者则通过建设高速公路信息化工程来解决这些问题。高速公路在交通运输中发挥着举足轻重的作用，然而在高速公路智能化信息平台建设方面却存在缺乏整体设计意识、系统间不能共享资源等严重问题，基于此，开展高速公路智能化信息平台的设计和总体规划研究变得非常具有价值。因此，论文首先介绍了当前国内外高速公路信息平台及相关核心技术的应用现状及趋势，其中支撑平台的核心技术包括多源信息感知和运行状态监测，从而提出当前平台存在的问题，进而提出了研究的意义与目的；并在其基础上从发挥平台整体效益出发，，采用自上而下与自下而上相结合的方式对信息平台进行体系架构的设计，包括逻辑框架与物理框架。通过深入分析基于车联网的高速公路交通信息平台关键技术，着重研究基于车联网的高速公路实时感知技术，同时构建基于车联网和ID3的交通状态判别算法；最后以德州的特大交通事故为例，结合车载智能手机导航系统，实现对地图匹配算法和交通状态判别算法的验证。从而有效解决我国智能交通建设中存在的诸多问题，为未来高速公路智能化建设提供有价值的参考。
[Abstract]:At present, the management of expressway in our country obviously lags behind the construction of expressway, resulting in the current situation that the speed of expressway is not high, and this has become the common feeling of many road users. Traffic accidents occur from time to time, resulting in huge loss of life and property. The seriousness of these problems has been gradually highlighted in the process of highway construction and management in China. The government managers solve these problems through the construction of highway information engineering. Expressway plays an important role in transportation. However, there are some serious problems in the construction of highway intelligent information platform, such as the lack of overall design consciousness and the inability to share resources among systems. It is very valuable to develop the design and overall planning of highway intelligent information platform. Therefore, the paper first introduces the current situation and trend of application of expressway information platform and related core technologies at home and abroad, among which the core technologies of supporting platform include multi-source information perception and operation state monitoring. The problems existing in the platform are put forward, and the significance and purpose of the research are put forward. On the basis of it, the paper designs the information platform architecture, including logical framework and physical framework, by combining top-down and bottom-up methods to give full play to the overall benefits of the platform. Through in-depth analysis of the key technologies of freeway traffic information platform based on vehicular networking, this paper focuses on the real-time sensing technology of freeway based on vehicular networking. At the same time, the traffic condition discrimination algorithm based on vehicle networking and ID3 is constructed. Finally, take the Texas traffic accident as an example, combined with the car smart phone navigation system. The algorithm of map matching and traffic state identification can be verified, which can effectively solve the problems existing in the construction of intelligent transportation in China, and provide valuable reference for the intelligent construction of expressway in the future.
