城市次干路集散功能可靠度量化評價與實證研究
發(fā)布時間：2019-06-12 06:32
【摘要】：依據(jù)《城市道路工程設計規(guī)范》(CJJ37—2012)關于次干路功能的闡述,以"支路車流經(jīng)過次干路匯集向主干路"和"主干路車流經(jīng)過次干路分散到支路"為研究對象,提出城市次干路集散功能可靠度的概念,作為定量評價次干路功能實現(xiàn)程度的概率測度指標,進而建立相應的數(shù)學模型.基于鄭州市區(qū)2條次干路,采用實地調(diào)查的延誤、信號配時和交通量數(shù)據(jù)資料,論證了非飽和情況下,車流由主干路向次干路和由次干路向支路分散,或由支路向次干路和由次干路向主路匯集的相鄰交叉口左轉(zhuǎn)延誤的不相關性;結合模型分別計算得到各自的集功能可靠度值、散功能可靠度值,與實際交通運行狀態(tài)進行對比分析,驗證了所提方法的可行性與適用性.
[Abstract]:According to the description of the function of the secondary trunk road in the Code for Design of Urban Road Engineering (CJJ37-2012), taking "the traffic flow of the branch road through the sub-trunk road to the main trunk road" and "the traffic flow of the main road passing through the sub-trunk road to the branch road" as the research objects, the concept of the reliability of the distributed function of the urban sub-trunk road is put forward, which is used as the probability measure index to quantitatively evaluate the realization degree of the sub-trunk road function, and then the corresponding mathematical model is established. Based on the data of delay, signal timing and traffic volume of two sub-trunk roads in Zhengzhou city, this paper demonstrates that there is no correlation between the left turn delay of traffic flow from the main road to the sub-trunk road and from the sub-trunk road to the branch road, or from the branch road to the secondary main road and the adjacent intersection from the sub-trunk road to the main road under the condition of non-saturation. Combined with the model, the reliability values of set function and scattered function are calculated respectively, which are compared with the actual traffic operation state, and the feasibility and applicability of the proposed method are verified.
