【摘要】：定位技術的進步為公交運行狀況評價提供精確的數(shù)據(jù)支持。但這些大量的數(shù)據(jù)需要科學高效的處理分析方法,才能夠獲得高價值的信息,獲得的信息也才能夠被應用到公交運行狀況的改善中。論文主要對公交車輛定位數(shù)據(jù)處理方法公交運行狀況評價和應用進行了探討。論文首先分析了公交車輛定位數(shù)據(jù)的特征,并介紹了數(shù)據(jù)預處理和標準化的必要性和具體方法,總結(jié)出大量公交定位數(shù)據(jù)的一般處理思路和處理流程。而后,本文對基于大量定位數(shù)據(jù)的公交運行狀況指標研究的必要性和目的進行了詳細分析,總結(jié)了公交運行狀況評價指標體系構建的原則,給出了適用指標以及如何基于大量車輛定位數(shù)據(jù)獲得所需指標的方法。本文還分析了公交運行狀況可視化的相關概念和意義,給出了公交運行狀況可視化的分類：公交運行軌跡可視化和公交運行狀況指標可視化,分別給出了示例,并對公交運行軌跡圖的幾何學指標進行了分析。本文在有公交車輛定位數(shù)據(jù)的情況下,精確地量化高峰時段和非高峰時段公交運行狀況的差異,并給出示例。本文也給出了對公交運行狀況指標和“可視化”圖像的分析的必要方向：運行軌跡可視化和運行指標可視化,并給出了示例,通過對各項運行指標的分析和公交運行“可視化”圖像的分析,可以發(fā)現(xiàn)以往難以發(fā)現(xiàn)的問題以及以往難以精確界定的問題：例如快速發(fā)現(xiàn)瓶頸和確定公交車輛高峰和平峰運行狀況的定量差異。本文在通過大量公交定位數(shù)據(jù)獲得相關公交運行狀況指標的基礎上,掌握公交區(qū)間運行時間規(guī)律,提供了一種干線公交專用道上公交優(yōu)先信號設置方法,在保證干線社會車輛的雙向綠波不受影響的情況下,使干線上公交車也獲得較為理想的干線雙向綠波通行帶。最后,本文在對傳統(tǒng)公交車輛到站預報的技術和方式分析的的基礎上,對公交站點間運行穩(wěn)定性進行了分析和分級,給出了基于歷史定位數(shù)據(jù)分級的公交到站預報的一般步驟。本文的研究,利于簡單方便地處理不同城市、不同線路、不同終端的定位數(shù)據(jù),有利于高效精確的掌握公交運行狀況特點,發(fā)現(xiàn)問題和改善公交運行狀況。
[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.
