城市道路平面交叉设计探讨(国外英文资料) Along with the development of urban construction, urban population swelling, urban road traffic pressure is more and more big, the intersection traffic congestion, delay, the environment problem increasingly prominent, a new design method of channelized traffic to ensure road traffic order, improve the efficiency of road traffic safety and traffic have a significant effect, design concept gradually get the attention of the governments at all levels. Based on the experience of urban road design in nanyang region, this paper discusses the cross-design of the plane. The intersection of natural design So-called intersection highly channelizing, separation is refers to the people, vehicles, road vehicles, noninterference, order, usually by the road, and traffic island with green belt separation lane, make all kinds of different types and different speed of vehicles, each other through along a certain direction. The forklift design can be designed by means of reasonable layout of traffic islands, traffic signs and ground lines to guide traffic in a certain direction or path. The basic principle of the design of the intersectionalized design Rule of separation: (1) highly channelizing design should as far as possible to reduce the interference between different traffic flow, guided by the traffic sign and marking in accordance with the traffic participants driveway separation, the separation, one car separation passage way, prompting of the road. (2) the guidance principle: clear the movement track of different traffic flow, traffic, lanes, via the one-way traffic, ban left measures such as the traffic flow. The main points of the design of the intersections (1) the import channel is appropriately broadened to match the traffic capacity of the section In theory, two levels is the same road intersection, the duration of your vehicles through the intersection only equivalent to about half of the link passage of time, traffic capacity of intersection int
