【摘要】：随着我国经济的发展,城市化进程的加快,导致了机动车的迅猛增长,使人们忽视了非机动车,同时伴随电动自行车作为新兴事物的加入,也使非机动车流的特性发生了一定的改变。人们在对车道宽度进行设计时,主要倾向于机动车,导致城市道路资源分配不合理,而且在老规范中并没有考虑到电动自行车。论文基于此,首先确定了非机动车道通行能力的研究方法,然后调查了非机动车流平均速度及对应的平均密度,运用交通流三参数基本关系,创建了非机动车道的通行能力模型,最终得到了不同车道宽度和不同电动自行车比例时非机动车道的通行能力。首先,对非机动车道的通行能力作了定义,即在一定服务水平条件下,单位时间内通过某一宽度的道路的某一断面的最大车辆数,并确定了非机动车道通行能力的分析方法为实测法;其次,通过对非机动车交通流进行调查,对非机动车群运行特性进行分析,确定了骑行者能接受的骑行状态处在C级服务水平,并对处在C级服务水平的非机动车群的速度和密度等特性进行了分析;同时,根据不同电动自行车比例构成、不同车道宽度情况下,符合某种状态的非机动车群的平均密度、平均速度的调查数据,运用MATLAB拟合得到了以电动自行车比例和车道宽度为自变量,非机动车道通行能力为因变量的拟合公式,基于此创建了非机动车道的通行能力模型,最后,根据不同宽度车道和不同电动自行车比例的数据,计算得到了不同车道宽度和不同电动自行车比例时非机动车道的通行能力。本文对非机动车道通行能力研究方法作了初步探索,丰富了加入电动自行车后的非机动车道通行能力理论体系。
[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.
