【摘要】：當代社會,交通對城市發(fā)展的作用不言而喻,然而近年來隨著交通擁堵問題的加重,交通溢流引起的城市交通路網(wǎng)格鎖作為交通擁堵的一種表現(xiàn)形式逐漸引起了人們的關注。城市交通路網(wǎng)格鎖預測技術以及在交通地理信息系統(tǒng)(Geographic Information System for Transportation, GIS-T)中交通事件演化顯示技術為智能交通系統(tǒng)的重要組成部分,對于提高城市交通智能化管理水平具有很大的推動作用。其中,GIS-T中交通事件演化顯示技術以其混合數(shù)據(jù)結構和強大的地理空間分析功能等優(yōu)點,近年來迅速發(fā)展,被廣泛應用于各專業(yè)領域。本文以交通波理論為基礎,首先對交通溢流現(xiàn)象進行概述,在虛擬路網(wǎng)的幾何模型中,對城市交通路網(wǎng)格鎖的傳播機制進行描述；然后,在交通波分析的基礎上,探討基于停車波模型的排隊長度的算法,提出排隊長度線性預測模型,為交通路網(wǎng)格鎖傳播范圍的預測問題奠定基礎；在此基礎上,’將城市交通路網(wǎng)格鎖傳播范圍的研究問題分為建立兩個模型的子問題,即：城市交通路網(wǎng)格鎖傳播模型和排隊長度線性預測模型。為解決交通路網(wǎng)格鎖形成的動態(tài)變化趨勢的顯式表達問題,本文利用北京超圖軟件股份有限公司研發(fā)的GIS平臺,在SuperMap Deskpro.net軟件中處理并制作地圖,在VS2008環(huán)境中利用SuperMap Objects組件和C#語言進行二次開發(fā)。首先,制作地圖并針對每個圖層建立相應的屬性表,屬性會隨著路網(wǎng)中的數(shù)據(jù)對應更新；然后,通過交叉口溢流查詢找到發(fā)生溢流的交叉口,將對應的幾何對象添加到跟蹤圖層中,并利用緩沖區(qū)分析、跟蹤層的應用等功能來實現(xiàn)動態(tài)跟蹤,從而實現(xiàn)城市交通路網(wǎng)格鎖傳播的動態(tài)可視化表達。綜上所述,本文以交通波理論為基礎,提出了城市交通路網(wǎng)格鎖傳播模型,并實現(xiàn)了GIS系統(tǒng)的開發(fā),實驗表明,該模型實用有效、系統(tǒng)能夠滿足實時性、穩(wěn)定性等要求。本研究為城市交通路網(wǎng)格鎖研究領域提供了新的思路,對于該領域的后繼工作奠定了一定基礎。
[Abstract]:In contemporary society, the role of traffic on urban development is self-evident. However, in recent years, with the aggravation of traffic congestion, the urban traffic network lock caused by traffic overflow has gradually attracted people's attention as a form of traffic congestion. Grid lock prediction technology of urban traffic network and traffic event evolution display technology in traffic geographic information system (Geographic Information System for Transportation, GIS-T) are important components of intelligent transportation system. It plays a great role in improving the intelligent management level of urban traffic. Among them, traffic event evolution display technology in GIS-T has been widely used in various professional fields because of its mixed data structure and powerful geo-spatial analysis function. Based on the theory of traffic wave, this paper first summarizes the phenomenon of traffic overflow, and describes the propagation mechanism of urban traffic network latch in the geometric model of virtual road network. Then, on the basis of traffic wave analysis, the algorithm of queue length based on parking wave model is discussed, and a linear prediction model of queue length is proposed, which lays a foundation for the prediction of grid lock propagation range of traffic network. On this basis, the research on the propagation range of urban traffic network latch is divided into two sub-models, namely, urban traffic network latch propagation model and queue length linear prediction model. In order to solve the problem of explicit expression of the dynamic change trend of traffic network latch, this paper uses the GIS platform developed by Beijing Hypergraph Software Co., Ltd to process and make the map in SuperMap Deskpro.net software. SuperMap Objects component and C # language are used for secondary development in VS2008 environment. First of all, make the map and establish the corresponding property table for each layer, the properties will be updated with the data in the road network. Then, the intersection where the overflow occurs is found through the intersection overflow query, and the corresponding geometric object is added to the tracking layer, and the dynamic tracking is realized by using the functions of buffer analysis and the application of the tracking layer. In order to realize the dynamic visual expression of grid lock propagation in urban traffic network. To sum up, based on the traffic wave theory, this paper puts forward the grid lock propagation model of urban traffic network, and realizes the development of GIS system. The experimental results show that the model is practical and effective, and the system can meet the requirements of real-time, stability and so on. This study provides a new idea for the research field of urban traffic network latch, and lays a certain foundation for the follow-up work in this field.
