A study on the optimization design of JiangYan highway separate grade crossing

In order to rationally choose the mutual cross modes of the two routes on different planes, we analyzed the optimization design of the highway separate grade crossing. Combining with the changeable design idea, from the point of survey and design, we put forward the several problems that should pay attention to when we make the optimization design, so as to choose the most optimal scheme and exert its function. So that the separate grade crossing not only satisfy the needs of the traffic function, correspond to the modes of the overall layout, but also ensure the coordination between road and the surrounding environment.
