无信号控制的交叉口行人过街的交通分析 摘要目前在我国城市交通管理系统中，往往只重视车辆交通，轻视步行交通，关于行人交通流控制问题的研究较少，常简单地将其笼统归入到机动车交通流的管理之中，在客观上造成了交叉口处不同类别的交通流在同一时间互相穿行，彼此干扰的现象，既影响了交通运行效率，又不利于交通安Unsignalized intersection traffic analysis of pedestrian crossing Abstract Pedestrians are the main urban traffic control, pedestrian traffic safety is an important urban transport system components. Currently in city traffic management system, emphasis is often placed vehicular traffic, pedestrian traffic contempt, on the pedestrian traffic flow control problem of small, often simply be classified into the general management of motor vehicle traffic flow into, in the objective the intersection, causing a traffic flow of different types of walking through each other at the same time, the phenomenon of serious interference with each other, not only affects the transport efficiency, not conducive to traffic safety. The intersection without signal control, the difficulties faced by pedestrians crossing the street, to analyze the intersection without signal control of traffic characteristics of pedestrian crossing, pedestrians in the intersection to reduce delays, for improving the safety of pedestrians crossing the street and intersection capacity, improve traffic the management level is of great significance. This paper studies the non-signal controlled pedestrian crossing intersection characteristics, characteristics of different pedestrian crossing, illegal crossing of the psychological as well as the risk of different locations across the street level were analyzed crossing facilities on the need to set the situation described. Key words Pedestrian crossing no signal control intersection delay 第章 ,行人穿越道路的需求量较大,过街的交通状况普遍较差. 当道路路幅较宽、机动车流量增大时,行人过街危险性将大增,特别是在无信号控制路段更是如此.我国行人过街存在很多问题，行人过街设施缺乏，行人强行穿越机动车流；行人过街设施设计不当，行人过街信号设置不合理；缺乏有效的交通管制。研究无信号控制路段行人过街的安全性、便捷性变得尤为重要。 第章 过街2.1 速度对交通事故的影响 速度对交通事故的发生以及严重程度有着直接影响, 是道路交通事故的重要诱因之一。交通调查显示, 车速越高, 发生事故的危险性也就越大,但是危险性与车速并不成线性关系。澳大利亚RTA研究速度与事故危险性的关系如表2-1所示。从表中可以看出, 速度每增大5 km/ h
