立体复合通道工程上下层交通转换方式设计研究

Research on the Design of Upper and Lower Level Traffic Switching Modes for a Three-dimensional Composite Corridor Project

上下层交通转换方式研究是复合立体通道的研究重点,以狮子洋过江通道项目为例,为尽可能发挥过江通道的作用,需对通道上下层之间的调节功能进行研究,在基于交通量预测的基础上,结合上下层功能定位、控制因素、应急疏解、实施条件、经济等多方面因素比选后择优确定推荐设置方式。

The study of upper and lower traffic conversion mode is the focus of the research on composite three-dimensional channel.Taking the Shiziyang Link Project as an example,in order to fulfll as much as possible the role of the river crossing,the regulatory function between the upper and lower levels of the corridor needs to be studied.Based on the basis of the traffic volume forecast,and combining with the upper and lower levels of the function of the positioning,control factors,emergency evacuation,the conditions of implementation,the economy,and other factors,the recommended setting method is proposed after comparisons.
