【摘要】：匝道或連接線與被交公路間平面交叉是服務型互通式立交的重要組成部分。該平面交叉區(qū)域設計的合理與否，不僅決定著該區(qū)域被交公路通行能力和服務水平的大小，還對整個服務型互通式立交的功能有重要的影響。國內外有關服務型互通式立交匝道或連接線與被交公路平面交叉的渠化方法及其適用性的研究甚少，所以本文對該區(qū)域平面交叉渠化方法及適用性進行研究，研究結果對保證整個互通式立交及其與被交公路連接的平面交叉區(qū)域的行車安全和通行能力有重要的現(xiàn)實意義。 本文在對我國服務型互通式立交常用的基本形式進行歸納和總結的基礎上，確定了服務型立交的匝道或連接線與被交公路之間T型平面交叉為研究對象。在分析平面交叉交通安全影響因素的基礎上，，結合不同等級被交公路的交通特性，對匝道或連接線與被交地方路間的平面交叉的交通特性進行分析。結合平面交叉渠化設計的目的和原則，對所研究的T型平面交叉渠化方法進行研究，并對不同的渠化方案劃分等級，確定不同等級的渠化方案的適應性，研究不同等級被交公路與匝道或連接線間的平面交叉渠化設計。使用VISSIM微觀交通仿真軟件分別對渠化前后的平面交叉交通運行情況進行模擬，對平面交叉渠化設計的合理性進行評價，最終確定服務型互通立交匝道與被交公路間平面交叉區(qū)域的渠化方案，達到了對該區(qū)域平面交叉的優(yōu)化，減少該區(qū)域交通事故的目的。論文還對存在交通問題的現(xiàn)狀互通式立交匝道或連接線與被交公路間的平面交叉，提出了近期和遠期的改善措施。
[Abstract]:The plane intersection between the ramp or connection line and the intersected highway is an important part of the service interchange.Whether the design of the plane crossing area is reasonable or not not only determines the traffic capacity and service level of the crossing road, but also has an important influence on the function of the whole service interchange.There are few researches at home and abroad on the method of channelization and its applicability of the horizontal intersection between the service type interchange ramp or the connecting line and the intersected highway, so this paper studies the method and applicability of the horizontal crossing channel in this area.The results of the study are of great practical significance to ensure the traffic safety and traffic capacity of the whole interchange and the plane crossing area connected with the intersected highway.On the basis of summing up the basic forms of service interchange in China, this paper determines the T-plane intersection between the ramp or connection line of service interchange and the intersected highway.On the basis of analyzing the influence factors of plane crossing traffic safety, combined with the traffic characteristics of different grade intersected highways, the traffic characteristics of the plane crossing between the ramp or the connecting line and the intersection road are analyzed.Combined with the purpose and principle of plane cross channelization design, this paper studies the T type plane cross channelization method, and classifies different channel schemes, and determines the adaptability of different levels of channelization schemes.This paper studies the design of plane crossing channel between different grade intersection highway and ramp or connection line.The running situation of plane cross traffic before and after canalization is simulated by VISSIM microcosmic traffic simulation software, and the rationality of plane cross channel design is evaluated.Finally, the channelization scheme of the plane crossing area between the service interchange ramp and the highway is determined, which achieves the purpose of optimizing the plane intersection of the area and reducing the traffic accidents in the area.The paper also puts forward the short-term and long-term improvement measures for the plane intersection between the interchange ramp or the connection line and the intersected highway.
