【摘要】：隨著我國經(jīng)濟的發(fā)展,城市化進程的加快,導(dǎo)致了機動車的迅猛增長,使人們忽視了非機動車,同時伴隨電動自行車作為新興事物的加入,也使非機動車流的特性發(fā)生了一定的改變。人們在對車道寬度進行設(shè)計時,主要傾向于機動車,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自行車。論文基于此,首先確定了非機動車道通行能力的研究方法,然后調(diào)查了非機動車流平均速度及對應(yīng)的平均密度,運用交通流三參數(shù)基本關(guān)系,創(chuàng)建了非機動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自行車比例時非機動車道的通行能力。首先,對非機動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),并確定了非機動車道通行能力的分析方法為實測法;其次,通過對非機動車交通流進行調(diào)查,對非機動車群運行特性進行分析,確定了騎行者能接受的騎行狀態(tài)處在C級服務(wù)水平,并對處在C級服務(wù)水平的非機動車群的速度和密度等特性進行了分析;同時,根據(jù)不同電動自行車比例構(gòu)成、不同車道寬度情況下,符合某種狀態(tài)的非機動車群的平均密度、平均速度的調(diào)查數(shù)據(jù),運用MATLAB擬合得到了以電動自行車比例和車道寬度為自變量,非機動車道通行能力為因變量的擬合公式,基于此創(chuàng)建了非機動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自行車比例的數(shù)據(jù),計算得到了不同車道寬度和不同電動自行車比例時非機動車道的通行能力。本文對非機動車道通行能力研究方法作了初步探索,豐富了加入電動自行車后的非機動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.
