【摘要】：隨著我國(guó)經(jīng)濟(jì)的發(fā)展,城市化進(jìn)程的加快,導(dǎo)致了機(jī)動(dòng)車的迅猛增長(zhǎng),使人們忽視了非機(jī)動(dòng)車,同時(shí)伴隨電動(dòng)自行車作為新興事物的加入,也使非機(jī)動(dòng)車流的特性發(fā)生了一定的改變。人們?cè)趯?duì)車道寬度進(jìn)行設(shè)計(jì)時(shí),主要傾向于機(jī)動(dòng)車,導(dǎo)致城市道路資源分配不合理,而且在老規(guī)范中并沒有考慮到電動(dòng)自行車。論文基于此,首先確定了非機(jī)動(dòng)車道通行能力的研究方法,然后調(diào)查了非機(jī)動(dòng)車流平均速度及對(duì)應(yīng)的平均密度,運(yùn)用交通流三參數(shù)基本關(guān)系,創(chuàng)建了非機(jī)動(dòng)車道的通行能力模型,最終得到了不同車道寬度和不同電動(dòng)自行車比例時(shí)非機(jī)動(dòng)車道的通行能力。首先,對(duì)非機(jī)動(dòng)車道的通行能力作了定義,即在一定服務(wù)水平條件下,單位時(shí)間內(nèi)通過某一寬度的道路的某一斷面的最大車輛數(shù),并確定了非機(jī)動(dòng)車道通行能力的分析方法為實(shí)測(cè)法;其次,通過對(duì)非機(jī)動(dòng)車交通流進(jìn)行調(diào)查,對(duì)非機(jī)動(dòng)車群運(yùn)行特性進(jìn)行分析,確定了騎行者能接受的騎行狀態(tài)處在C級(jí)服務(wù)水平,并對(duì)處在C級(jí)服務(wù)水平的非機(jī)動(dòng)車群的速度和密度等特性進(jìn)行了分析;同時(shí),根據(jù)不同電動(dòng)自行車比例構(gòu)成、不同車道寬度情況下,符合某種狀態(tài)的非機(jī)動(dòng)車群的平均密度、平均速度的調(diào)查數(shù)據(jù),運(yùn)用MATLAB擬合得到了以電動(dòng)自行車比例和車道寬度為自變量,非機(jī)動(dòng)車道通行能力為因變量的擬合公式,基于此創(chuàng)建了非機(jī)動(dòng)車道的通行能力模型,最后,根據(jù)不同寬度車道和不同電動(dòng)自行車比例的數(shù)據(jù),計(jì)算得到了不同車道寬度和不同電動(dòng)自行車比例時(shí)非機(jī)動(dòng)車道的通行能力。本文對(duì)非機(jī)動(dòng)車道通行能力研究方法作了初步探索,豐富了加入電動(dòng)自行車后的非機(jī)動(dòng)車道通行能力理論體系。
[Abstract]:With the development of China's economy and the acceleration of urbanization, the rapid growth of motor vehicles has led to the neglect of non-motor vehicles, as well as the addition of electric bicycles as a new thing. It also changes the characteristics of non-motor vehicle flow. In the design of lane width, people mainly tend to motor vehicle, which leads to unreasonable allocation of urban road resources, and does not take electric bicycle into account in the old code. Based on this, this paper first determines the research method of non-motorized lane capacity, then investigates the average velocity and the corresponding average density of non-motor vehicle flow, and applies the basic relationship of three parameters of traffic flow. The capacity model of non-motorized lane is established and the capacity of non-motorized lane with different lane width and different proportion of electric bicycle is obtained. First, the capacity of a non-motorized lane is defined as the maximum number of vehicles passing through a section of a road of a certain width within a given service level. The analysis method of non-motorized lane capacity is determined as the measured method. Secondly, through the investigation of non-motor vehicle traffic flow, the operation characteristics of non-motor vehicle group are analyzed. The acceptable riding condition of cyclists is determined to be at the C level of service, and the characteristics of the speed and density of the non-motor vehicle group at the C level of service are analyzed. At the same time, according to the different proportion of electric bicycle, the speed and density of the non-motor vehicle group are analyzed. Under different lane widths, the investigation data of average density and average speed of non-motor vehicle groups in a certain state are obtained by MATLAB fitting, and the ratio and lane width of electric bicycle are taken as independent variables. Based on the fitting formula of non-motorized lane capacity as dependent variable, the capacity model of non-motorized lane is established. Finally, according to the data of different width lane and different proportion of electric bicycle, The capacity of non-motorized lane with different lane width and different proportion of electric bicycle is calculated. This paper makes a preliminary exploration on the research method of non-motorized lane capacity, which enriches the theoretical system of non-motorized lane capacity after adding electric bicycle.
