【摘要】：平面交叉口是城市道路的重要組成,也是整個(gè)城市道路網(wǎng)的“瓶頸”,平面交叉口處發(fā)生擁堵現(xiàn)象和交通事故的概率要遠(yuǎn)遠(yuǎn)大于道路路段部分,影響著整條道路,甚至整個(gè)城市道路網(wǎng)的功能。平面交叉口的合理設(shè)計(jì)關(guān)系著城市道路的安全性、通行能力和整個(gè)路網(wǎng)容量。合理的交通組織和渠化設(shè)計(jì)可以在投入較少的情況下,達(dá)到較好利用平交口時(shí)空資源,挖掘道路潛在通行能力的作用,可謂是城市道路建設(shè)最具性價(jià)比的措施。論文分析了參與平面交叉口交通行為的行人和機(jī)非車輛三種主要交通流的出行特征和混合交通下的交通沖突特征,在此基礎(chǔ)上論述了平面交叉口交通組織的原則和方法,論述了渠化設(shè)計(jì)的特點(diǎn)和方法,提出了不同方法的適用性。針對我國現(xiàn)行規(guī)范中對魚肚形導(dǎo)流島設(shè)置左轉(zhuǎn)車道的設(shè)計(jì)參數(shù)規(guī)定不明確的問題,將其劃分為過渡段、駛?cè)攵�、減速段和停駐段四個(gè)功能段,根據(jù)不同設(shè)計(jì)速度提出了保證行車安全性與舒適性的各功能段長度及設(shè)計(jì)參數(shù);為了增加魚肚形導(dǎo)流島設(shè)置左轉(zhuǎn)車道的適用性,提出了奇數(shù)車道的設(shè)置條件和如何在沿河或山區(qū)等曲線較多路段設(shè)計(jì)魚肚形導(dǎo)流島的方法;參考魚肚形導(dǎo)流島設(shè)置左轉(zhuǎn)車道過渡段長度的研究辦法,確定了拓寬進(jìn)口道設(shè)置右轉(zhuǎn)車道的過渡段長度及設(shè)計(jì)參數(shù);運(yùn)用停車視距原理得出了拓寬進(jìn)口道設(shè)置右轉(zhuǎn)車道的拓寬段長度;通過實(shí)地?cái)?shù)據(jù)采集建立了VISSIM仿真模型,驗(yàn)證了左、右轉(zhuǎn)渠化設(shè)計(jì)的應(yīng)用效果;對于右轉(zhuǎn)導(dǎo)流島及導(dǎo)流路設(shè)計(jì),也根據(jù)不同的車輛組合給出了導(dǎo)流路寬度。在標(biāo)志標(biāo)線平面示意圖的基礎(chǔ)上介紹了魚肚形導(dǎo)流島設(shè)置左轉(zhuǎn)車道、拓寬進(jìn)口道設(shè)置右轉(zhuǎn)車道、右轉(zhuǎn)導(dǎo)流島及導(dǎo)流路設(shè)計(jì)中應(yīng)用到的標(biāo)志標(biāo)線,提出了交通工程設(shè)計(jì)中應(yīng)該注意的問題,保證交通安全并便于車輛遵循。本文的研究結(jié)論為完善城市道路平交口渠化和導(dǎo)流島的設(shè)計(jì)提供了參考。
[Abstract]:Intersection is an important component of urban roads, but also the "bottleneck" of the entire urban road network. The probability of congestion and traffic accidents at intersections is far greater than the part of road sections. It affects the function of the whole road, even the whole city road network. The rational design of the intersection is related to the safety of the city road. Capacity and capacity of the whole road network reasonable traffic organization and channelization design can make better use of the space-time resources of the horizontal intersection and excavate the potential capacity of the road under the condition of less investment. It can be described as the most cost-effective measure of urban road construction. This paper analyzes the travel characteristics of pedestrian and non-vehicle traffic flow and the characteristics of traffic conflict under mixed traffic. On this basis, the principles and methods of traffic organization at intersections are discussed, and the characteristics and methods of channelization design are discussed. The applicability of different methods is put forward. Aiming at the problem that the design parameters of the left turning lane are not clear in the current code of our country, it is divided into transition section and driving section. According to the different design speed, the length and design parameters of each functional segment to ensure the safety and comfort of the vehicle are put forward. In order to increase the applicability of the left turning lane, the conditions of setting odd-numbered driveway and the method of designing fish-belly diversion island in more curve sections along river or mountainous area are put forward. Referring to the research method of the length of the transition section of the left turning lane set up on the fish-stomach guide island, the length and design parameters of the transition section of the right turning lane for widening the entrance road are determined. The length of the widening section of the right turning lane is obtained by using the principle of parking sight distance. The VISSIM simulation model is established through the field data collection, and the application effect of the left and right turn canal design is verified. For the design of right-turn guide island and guide road, the width of the guide road is also given according to different vehicle combinations. On the basis of the graphic diagram of marking line, the left turning lane of fish-belly guide island is introduced. The design of the right turning lane, the right turn guide island and the sign mark used in the design of the diversion road are expanded. The problems that should be paid attention to in the traffic engineering design are put forward. The conclusion of this paper provides a reference for the improvement of the design of urban road channel and diversion island.
