【摘要】：城市道路上有较大过街需求的地点需设置过街设施,而平面过街设施是最常用的过街设施形式。路段平面过街设施设置的不合理会加剧行人过街交通与道路机动车交通的矛盾,诱增路段上机动车行车延误和行人过街的危险性,因此对于路段平面过街设施的合理设置是有必要研究的,为了更好的解决这一实际问题,本文从路段人行横道的地点和合理间距的设置方法进行了研究。本文首先从国内外学者的文献著作和现行的规范条款两方面回顾平面过街设施的设置位置和间距的研究;其次,在实际调查的基础上,详细分析了行人过街交通特性,确定了行人过街速度、行人过街横向宽度、行人可接受间隙等过街特征的取值,并从过街到达率和可接受绕行距离两方面分析了人行横道间距对过街行人的影响,分析了路段机动车流的离散性、行驶时间、通过人行横道的延误和行驶车速,并对机动车流受人行横道的影响进行了研究;然后,基于人行横道间距对行人、机动车流状态的影响,研究了人行横道间距对于路段机动车道、路段人行横道的通行能力和服务水平的影响;最后,考虑行人流量与人行横道设计通行能力关系、行人可接受绕行距离确定平面行人过街设施合理间隔取值的上限,通过机动车流量与路段设计通行能力关系、机动车运行速度与设计服务水平的关系确定平面行人过街设施间隔取值的下限,提出路段平面过街设施合理间距的计算方法,最终得出路段平面过街设施的合理间距范围计算公式。并给出算例说明,及具体的城市道路环境中过街设施间距的取值。研究结果对于在实际城市交通设计中,路段人行横道布设的间距取值具有一定的借鉴意义。
[Abstract]:Cross-street facilities are required at locations where there is a greater demand for cross-street traffic on urban roads. The plane crossing facilities are the most commonly used crossing facilities. The unreasonable setting of plane crossing facilities on road sections will aggravate the contradiction between pedestrian crossing traffic and road motor vehicle traffic. In order to solve this practical problem, it is necessary to study the reasonable setting of road section plane crossing facilities because of the danger of vehicle delay and pedestrian crossing. In this paper, the setting method of the location and reasonable spacing of pedestrian crossing is studied. Firstly, this paper reviews the location and spacing of plane crossing facilities from the literature works of domestic and foreign scholars and the current regulations. Research; Secondly, on the basis of actual investigation, the characteristics of pedestrian crossing traffic are analyzed in detail, and the values of pedestrian crossing speed, pedestrian transverse width and pedestrian acceptable clearance are determined. The influence of crosswalk spacing on pedestrian is analyzed from two aspects of the crossing arrival rate and acceptable bypass distance. The discreteness, driving time, delay and speed of passing crosswalk are analyzed. The influence of pedestrian crossing on the flow of motor vehicles is also studied. Then, based on the influence of crosswalk spacing on pedestrian and motor vehicle flow, the influence of crosswalk spacing on traffic capacity and service level of road sections is studied. Finally, considering the relationship between pedestrian flow and pedestrian crossing design capacity, pedestrians can accept bypass distance to determine the upper limit of reasonable interval of pedestrian crossing facilities. Through the relationship between the vehicle flow and the design capacity of the road section, and the relationship between the speed of the motor vehicle and the design service level, the lower limit of the interval value of the pedestrian crossing facilities is determined. This paper puts forward the calculation method of the reasonable distance between the plane crossing facilities of the road section, and finally obtains the calculation formula of the reasonable distance range of the plane crossing facilities of the road section, and gives an example to illustrate the calculation. The results can be used for reference in practical urban traffic design.
