Ø 矩阵修改
矩阵文件不能直接被修改
虽然不能直接修改矩阵文件，但可使用简单的scripts来修改。
There is no graphic matrix editor. But, you can write simple scripts to modify matrices.
Ø 与其他公司模型的接口
与EMME/2、transcad、PTV VISUM等软件没有接口
市面上其他软件的网路档可先转成shape 档即可输入到CUBE中
Cube can not use TransCAD, EMME/2 file directly, but you can always export a transcad or EMME/2 network file to a shape file, and then import the shape file to CUBE.
Ø 没有U-turn
没有U-turn功能
U-turn 虽不能直接表示在CUBE的网路中但仍能以间接的手段来表示。
You can not directly add u-turn to a cube network, but you can immiate a u-turn by adding additional dummy nodes. U-turn can be represented on a CUBE network, it all depends on how you create the network.
