【摘要】：全球各大城市如今都不同程度的受到交通擁擠問題的困擾,在我國伴隨著三十多年的高速發(fā)展引發(fā)的城市交通問題尤為嚴重,交通擁擠已成為城市面臨的主要社會問題之一,嚴重影響到人們的日常生產(chǎn)和生活�？焖佟蚀_、實時地識別道路交通擁堵狀態(tài)和對道路運行狀態(tài)的長期連續(xù)監(jiān)測,對于制定合理有效的城市交通管理策略具有重要意義。同時隨著GPS/GIS技術(shù)在城市出租車運營管理中的推廣應用,使得人們能夠很便捷的獲取出租車營運過程中的GPS數(shù)據(jù),并為挖掘這部分數(shù)據(jù)在城市道路交通管理和建設方面的價值提供了可能。本文首先研究了城市道路交通流的基本特性,并提出了將出租車作為GPS浮動車的優(yōu)越性,及相比普通社會車輛出租車運行的特性。其次依托城市出租車GPS中心系統(tǒng)可以便捷的實現(xiàn)對出租車GPS定位數(shù)據(jù)的實時采集及存儲,并結(jié)合出租車GPS數(shù)據(jù)的結(jié)構(gòu)特性和出租車行駛特性提出了不同載客狀態(tài)下的數(shù)據(jù)篩選方法,提高了數(shù)據(jù)樣本的質(zhì)量和使用率,并提出不同情況下的路段平均行程速度和交叉口平均行程延誤時間估計算法。此外,考慮到數(shù)據(jù)樣本量大小對路段平均行程速度估計精度的影響,提出基于自適應加權(quán)指數(shù)平滑法的路段平均行程速度估計方法。最后基于模糊評價的理論,建立以路段平均行程速度和交叉口平均行程延誤作為度量指標的道路交通運行狀態(tài)判別方法。通過本文的研究,將出租車作為GPS浮動車能夠很好的實現(xiàn)對城市道路運行狀態(tài)的監(jiān)測,對城市交通的管理、建設和研究具有重大意義。
[Abstract]:Nowadays, all the major cities in the world are troubled by traffic congestion in varying degrees. With the rapid development of more than 30 years in our country, the urban traffic problem is especially serious. Traffic congestion has become one of the main social problems facing the city, which seriously affects people's daily production and life. Real-time identification of road traffic congestion and long-term continuous monitoring of road running state. At the same time, with the application of GPS/GIS technology in urban taxi operation and management, it is of great significance to establish a reasonable and effective urban traffic management strategy. So that people can easily access the taxi operation process of GPS data. And for mining the value of this part of the data in urban road traffic management and construction of the possible. Firstly, this paper studies the basic characteristics of urban road traffic flow. The superiority of using taxi as GPS floating vehicle is put forward. Secondly, relying on the city taxi GPS center system can conveniently realize the real-time collection and storage of taxi GPS positioning data. Combined with the structural characteristics of taxi GPS data and taxi driving characteristics, this paper proposes a data screening method under different passenger status, which improves the quality and utilization of data samples. An algorithm for estimating the average travel speed and the average travel delay time of intersection under different conditions is proposed. In addition, the effect of the size of the data sample size on the accuracy of the estimation of the average travel speed is considered. An adaptive weighted exponential smoothing method is proposed to estimate the average travel speed of road sections. Finally, the theory of fuzzy evaluation is used. This paper establishes a method of judging road traffic running state based on the average travel speed of road and the average travel delay of intersection. Using taxi as a GPS floating vehicle can monitor the running state of urban roads and has great significance for the management, construction and research of urban traffic.
