【摘要】：隨著經(jīng)濟的快速發(fā)展和城市化進程的不斷推進,城市交通擁堵問題日益普遍和突出。為反映城市道路交通的運行狀態(tài),一系列道路交通擁堵指標(biāo)被提出。但是擁堵指標(biāo)的提出往往是針對某一特定城市或地區(qū)進行的,然而不同的城市具有不同的路網(wǎng)屬性,城市交通運行狀態(tài)的特點也就有所區(qū)別,這就導(dǎo)致了交通擁堵指標(biāo)對不同城市存在著適用性問題。在此背景下,本文針對應(yīng)用較廣泛的動態(tài)交通運行指數(shù)模型,研究其在不同路網(wǎng)屬性的城市的適用性。首先,本文在對國內(nèi)外交通運行指數(shù)模型進行梳理歸納的基礎(chǔ)上,將可實時反映路網(wǎng)運行狀態(tài)的動態(tài)運行指數(shù)模型分為基于嚴重擁堵里程比的交通運行指數(shù)模型和基于出行時間比的交通運行指數(shù)模型。然后將兩種動態(tài)交通運行指數(shù)模型應(yīng)用于同一路網(wǎng),觀察到兩種動態(tài)交通運行指數(shù)模型在同一路網(wǎng)下的應(yīng)用結(jié)果具有一定差異性,進而提出了本文的研究重點,即不同路網(wǎng)屬性下動態(tài)交通運行指數(shù)模型的適用性研究問題。為了對此問題進行研究,本文做了一系列準(zhǔn)備工作:在分析城市分類及路網(wǎng)屬性基礎(chǔ)上,設(shè)計了典型城市路網(wǎng)規(guī)模和級配比參數(shù),并以北京市路網(wǎng)為樣本總體,采用隨機數(shù)生成法和最小樣本量確定法,進行了各類城市虛擬路網(wǎng)庫的構(gòu)建,為本文研究提供了路網(wǎng)基礎(chǔ);通過對浮動車數(shù)據(jù)(FCD)的計算分析,選擇了三類交通運行狀態(tài),為本文研究提供了交通運行數(shù)據(jù)基礎(chǔ);為提高動態(tài)運行指數(shù)模型的應(yīng)用效率,應(yīng)用SQL server工具通過編寫程序進行模型應(yīng)用計算,為研究提供了模擬計算手段�；谝陨蠝�(zhǔn)備工作,本文將兩種動態(tài)運行指數(shù)模型應(yīng)用于所選定的FCD和所構(gòu)建的虛擬路網(wǎng),進而得出了模型應(yīng)用的指數(shù)結(jié)果。借鑒信號處理方法與指標(biāo),提出了對模型適用性進行評價的敏感性指標(biāo)(SI)和穩(wěn)定性指標(biāo)(FI)兩項單項指標(biāo)。在對單項指標(biāo)標(biāo)準(zhǔn)化后加權(quán)求得綜合性評價指標(biāo)(CEI),進而提出了對動態(tài)交通運行指數(shù)模型的適用性判別方法。最后,本文以不同城市類別為劃分,對所提出的動態(tài)交通運行指數(shù)模型的適用性判別方法進行應(yīng)用研究,證實了所提出方法的可行性與有效性。
[Abstract]:With the rapid development of economy and the development of urbanization, urban traffic congestion is becoming more and more common and prominent. In order to reflect the running state of urban road traffic, a series of road traffic congestion indicators have been proposed. However, the proposed congestion index is usually aimed at a particular city or region. However, different cities have different road network properties, so the characteristics of urban traffic operation state are different. This leads to the applicability of traffic congestion index to different cities. Under this background, this paper studies the applicability of the dynamic traffic operation index model which is widely used in cities with different road network properties. First of all, on the basis of combing and summing up the domestic and foreign traffic operation index model, The dynamic operation index model, which can reflect the running state of road network in real time, is divided into traffic operation index model based on serious traffic congestion mileage ratio and traffic operation index model based on trip time ratio. Then two kinds of dynamic traffic operation index models are applied to the same road network, and the results of the two dynamic traffic operation index models in the same road network are observed to be different, and the research emphasis of this paper is put forward. That is, the applicability of dynamic traffic operation index model under different road network attributes. In order to study this problem, this paper makes a series of preparatory work: on the basis of analyzing the city classification and road network attribute, the paper designs the typical city network scale and grade matching parameters, and takes Beijing road network as a sample. By using random number generation method and minimum sample size determination method, all kinds of urban virtual road network library are constructed, which provides the road network foundation for the study of this paper, through the calculation and analysis of floating vehicle data (FCD), three kinds of traffic operation state are selected. In order to improve the application efficiency of the dynamic operation index model, the model application calculation is carried out by programming the server tool, which provides the means of simulation calculation for the research. Based on the above work, two kinds of dynamic operation index models are applied to the selected FCD and the virtual road network, and the exponential results of the application of the model are obtained. Based on the signal processing method and index, two single indexes, sensitivity index (SI) and stability index (fi), are proposed to evaluate the applicability of the model. The comprehensive evaluation index (CEI) is obtained after the standardization of the single index, and the applicability of the dynamic traffic operation index model is proposed. Finally, based on the classification of different cities, the applicability of the proposed dynamic traffic operation index model is studied, which proves the feasibility and effectiveness of the proposed method.
