【摘要】：隨著城市道路兩側(cè)土地開(kāi)發(fā)利用強(qiáng)度的增加,道路兩側(cè)出入口的數(shù)量不斷增長(zhǎng),一方面提高了用地區(qū)域的可達(dá)性,使得車輛能夠更加方便地抵達(dá)目的地,另外一方面,出入口車輛的頻繁進(jìn)出,則會(huì)對(duì)主路直行交通流造成一定的負(fù)面影響。為了協(xié)調(diào)道路的可達(dá)性和通過(guò)性之間的關(guān)系,使得道路的服務(wù)效率最大化,本文探討了不同類型單個(gè)出入口車輛運(yùn)行特性對(duì)主路機(jī)動(dòng)車交通流造成的動(dòng)態(tài)影響,以及多個(gè)出入口之間相互影響,并提出城市道路路段出入口接入條件和出入口優(yōu)化組織策略。首先本文綜合分析了國(guó)內(nèi)外出入口的研究現(xiàn)狀,歸納并總結(jié)了前人研究成果和不足之處,在此基礎(chǔ)上提煉出本文的研究?jī)?nèi)容。然后針對(duì)研究對(duì)象進(jìn)行交通調(diào)查,根據(jù)調(diào)查數(shù)據(jù)分析出入口處的車輛運(yùn)行特性和出入口路段的基本交通特性,車輛運(yùn)行特性包括駛離主路車輛的到達(dá)、離去以及在機(jī)動(dòng)車道停留的時(shí)間,路段交通特性包括車頭時(shí)距、流量、速度和車輛換道時(shí)間。依據(jù)車輛到達(dá)率和離去率劃分出入口類型：根據(jù)轉(zhuǎn)向車輛停留時(shí)間區(qū)分不同出入口類型對(duì)主路的影響。在單個(gè)出入口對(duì)主路的影響方面,分別就無(wú)排隊(duì)出入口和排隊(duì)出入口不同車道建立了路段初始速度模型,然后基于跟馳減速、受阻換道、排隊(duì)占道三種不同影響機(jī)理,建立了出入口影響條件下的速度影響模型,運(yùn)用交通調(diào)查數(shù)據(jù)對(duì)模型進(jìn)行標(biāo)定和參數(shù)敏感性分析。接著提出速度影響區(qū)概念,基于波動(dòng)理論和速度影響模型,建立了各車道速度影響區(qū)長(zhǎng)度模型,并對(duì)其中的駛離影響時(shí)間、換道車輛速度差、占道車輛排隊(duì)長(zhǎng)度等關(guān)鍵變量進(jìn)行了參數(shù)敏感性分析。無(wú)排隊(duì)出入口外側(cè)車道的速度影響區(qū)長(zhǎng)度大于中間和內(nèi)側(cè)車道影響區(qū),排隊(duì)出入口被占用車道相鄰車道的速度影響區(qū)長(zhǎng)度的決定性因素是排隊(duì)長(zhǎng)度。在不同類型出入口組合影響研究時(shí),利用仿真軟件工具,采取before-after的試驗(yàn)方法,主要研究了上游出入口對(duì)下游出入口速度影響區(qū)范圍內(nèi)交通運(yùn)行狀況的影響,以行程時(shí)間作為對(duì)比指標(biāo)。得到路段流量、出入口轉(zhuǎn)向比、排隊(duì)長(zhǎng)度等試驗(yàn)因子對(duì)下游出入口影響區(qū)范圍行程時(shí)間的一般影響規(guī)律,并利用Lasso回歸的方法得到了不同類型組合的行程時(shí)間計(jì)算公式,評(píng)定了不同試驗(yàn)因子的影響強(qiáng)弱程度。最后,選取路段平均車速為評(píng)價(jià)指標(biāo),基于前文關(guān)于單個(gè)出入口和多個(gè)出入口的研究成果,采用路段多區(qū)段加權(quán)平均的方式計(jì)算路段平均車速,以滿足路段服務(wù)水平為目標(biāo),提出城市道路出入口合理接入條件的判定流程和出入口優(yōu)化組織策略。本文通過(guò)描述解析了城市道路出入口處的交通運(yùn)行特性和交通流特性,深入理解了不同類型出入口對(duì)城市道路不同車道的影響作用機(jī)理及上下游出入口之間的相互影響機(jī)理。提出出入口速度影響區(qū)概念,從城市道路運(yùn)行效率的角度出發(fā),為出入口間距的確定提供了參考方法和依據(jù)。
[Abstract]:With the city on both sides of the road land use intensity increase, on both sides of the road entrance to the growing number of one hand to improve the accessibility of the region, so that the vehicle can be more convenient to reach the destination, on the other hand, frequent entrance out of the vehicle, will be on the main road straight traffic flow have a negative impact sure. In order to coordinate the road accessibility and through the relationship between the maximization of road service efficiency, this paper discusses the different types of single operation characteristics of dynamic effects caused by vehicle entrance to the main road traffic flow, and the mutual influence between a plurality of entrance, and put forward the city road entrance access entrance conditions and optimization strategy for organization. First this paper analyzes the research status at home and abroad entrance, and summarizes the previous research achievements and shortcomings, on this basis Refine the content of this paper. Then the traffic survey based on the research object, according to the traffic characteristics of survey data analysis at the entrance and exit sections of the basic traffic characteristics, including the characteristics of the vehicle off the main road running vehicles arrival, departure time and stay in the vehicle, road traffic characteristics including headway, traffic speed, and lane changing time. According to the vehicle arrival rate and departure rate divided into types: according to the vehicle entrance residence time different entrance type effect on the main road. The effect of single entrance to the main road side, respectively, without queuing and exit the queue entrance lane established different sections of initial velocity based on the model, then the following deceleration, blocked change, queuing lane and three different influence mechanism, set up the entrance effects under the conditions of velocity model, the use of traffic The survey data analysis was carried out on the model calibration and parameter sensitivity. Then the speed affected zone concept, impact wave theory and model based on the velocity, the establishment of a model of the effect of the length of time of departure and lane speed, the vehicle speed, lane change, road vehicle queue length key variable parameter sensitivity analysis was conducted. No queuing outside lane entrance velocity affected zone length is greater than the middle and the inside lane affected zone, queuing entrance occupied Lane adjacent lane speed affected zone length of the decisive factor is the queue length. In the study of effects of combination of different types of the entrance, by using the simulation software tools, adopt before-after test methods, mainly on the upstream the entrance to the downstream effects of entrance velocity within the affected zone traffic condition, travel time as compared to link flow index. The amount of entrance, steering ratio, queue length of the downstream entrance effect factor test general influence range of travel time, and using the method of Lasso regression obtained the travel time of different types of combination formula, evaluation test of different factors influencing the strength degree. Finally, select the average link speed as the evaluation index. Above a single entrance and a number of research results based on the road entrance, multi section weighted average method to calculate the average link speed, to meet the road service level as the goal, the city road entrance reasonable access conditions determine the entrance flow and optimization strategy for organization. This paper describes the analysis of the city road entrance the traffic characteristics and traffic flow characteristics, in-depth understanding of the different types of entrance to the city road effect mechanism of different lanes and a downstream The mechanism of interaction between entries is put forward. The concept of entry speed impact area is put forward. From the perspective of urban road operation efficiency, it provides a reference method and basis for determining the distance between the entry and exit.
