城市道路平面交叉口优化设计

The optimization design of city road plane intersection

论述了城市道路平面交叉口优化设计,通过实例运用交通标志、标线和实体设施以及局部展宽进口端,设置左、右转专用车道等措施来减少车与车、人与车冲突或明确分开冲突,形成一个有序的道路交通系统,真正实现城市道路的安全、通畅,并实质性地提高了整个城市的交通能力。

This paper discussed the optimization design of city road plane intersection, through the example using traffic signs, marking and phys- ical facilities and local broadening imported end, setting the left and right turn lanes and other measures to reduce vehicle and vehicle, people and cars conflict or clearly separated the conflict, forming an ordered the road traffic system, achieve really the urban road safety, unobstructed, and substantially improved the traffic capacity of whole city.
