【摘要】：定位技术的进步为公交运行状况评价提供精确的数据支持。但这些大量的数据需要科学高效的处理分析方法,才能够获得高价值的信息,获得的信息也才能够被应用到公交运行状况的改善中。论文主要对公交车辆定位数据处理方法公交运行状况评价和应用进行了探讨。论文首先分析了公交车辆定位数据的特征,并介绍了数据预处理和标准化的必要性和具体方法,总结出大量公交定位数据的一般处理思路和处理流程。而后,本文对基于大量定位数据的公交运行状况指标研究的必要性和目的进行了详细分析,总结了公交运行状况评价指标体系构建的原则,给出了适用指标以及如何基于大量车辆定位数据获得所需指标的方法。本文还分析了公交运行状况可视化的相关概念和意义,给出了公交运行状况可视化的分类：公交运行轨迹可视化和公交运行状况指标可视化,分别给出了示例,并对公交运行轨迹图的几何学指标进行了分析。本文在有公交车辆定位数据的情况下,精确地量化高峰时段和非高峰时段公交运行状况的差异,并给出示例。本文也给出了对公交运行状况指标和“可视化”图像的分析的必要方向：运行轨迹可视化和运行指标可视化,并给出了示例,通过对各项运行指标的分析和公交运行“可视化”图像的分析,可以发现以往难以发现的问题以及以往难以精确界定的问题：例如快速发现瓶颈和确定公交车辆高峰和平峰运行状况的定量差异。本文在通过大量公交定位数据获得相关公交运行状况指标的基础上,掌握公交区间运行时间规律,提供了一种干线公交专用道上公交优先信号设置方法,在保证干线社会车辆的双向绿波不受影响的情况下,使干线上公交车也获得较为理想的干线双向绿波通行带。最后,本文在对传统公交车辆到站预报的技术和方式分析的的基础上,对公交站点间运行稳定性进行了分析和分级,给出了基于历史定位数据分级的公交到站预报的一般步骤。本文的研究,利于简单方便地处理不同城市、不同线路、不同终端的定位数据,有利于高效精确的掌握公交运行状况特点,发现问题和改善公交运行状况。
[Abstract]:The advancement of positioning technology provides accurate data support for the evaluation of bus operation. However, these large amounts of data need scientific and efficient processing and analysis to obtain high value information. The information obtained can also be applied to the improvement of public transport operation. This paper mainly discusses the evaluation and application of bus location data processing method. Firstly, the paper analyzes the location of public transport vehicles. The character of the bit data. And introduced the data preprocessing and standardization of the necessity and specific methods, summed up a large number of bus positioning data general thinking and processing flow. In this paper, the necessity and purpose of the research on the public transport operation status indicators based on a large number of positioning data are analyzed in detail, and the principles for the construction of the evaluation index system of the public transport operation status are summarized. The suitable index and the method of how to get the needed index based on a large number of vehicle positioning data are given. The paper also analyzes the related concepts and significance of the visualization of public transport operation. In this paper, the classification of bus operation visualization is given, which includes the visualization of bus operation trajectory and the visualization of bus operation index, and some examples are given respectively. In this paper, with the location data of public transport vehicles, we accurately quantify the difference between peak and off-peak times. This paper also gives the necessary direction of the analysis of the public transport running condition index and the "visualization" image: the visualization of the running track and the visualization of the operation index, and gives an example. Through the analysis of the operation index and the analysis of the "visual" image of the public transport operation. Problems that have been difficult to detect in the past and those that have been difficult to define precisely in the past can be identified:. For example, rapid detection of bottlenecks and determination of bus traffic peak and peak operation of the quantitative difference. This paper based on a large number of public transport location data to obtain the relevant public transport operation indicators. In order to master the running time rule of public transport section, a method of setting bus priority signal on trunk bus lane is provided, which can ensure that the two-way green wave of the trunk line social vehicle will not be affected. So that the bus on the trunk line also get a more ideal two-way green wave traffic belt. Finally, this paper based on the traditional bus arrival prediction technology and method analysis. The stability of bus stations is analyzed and classified, and the general steps of bus arrival prediction based on historical positioning data are given. The research in this paper is helpful to deal with different cities simply and conveniently. The location data of different lines and terminals can help to grasp the characteristics of public transport operation, find problems and improve the operation of public transportation.
