Road parameters are an important basic setting, It determines what method to calculated this road, the location of the vertical curve, etc.
Tips: It is recommended not to make random changes later.
There are two input methods for horizantal curve parameters: PI(point of intersection) method & line element method.
The PI requires less parameter input and is simple, but its applicability is general. The line element method has strong applicability and is basically applicable to all lines, but the input is a bit troublesome.
Before inputting a horizantal curve, user needs to select the input method. The default is line element method. Please do not change it at will after selection, otherwise it will cause the loss of horizantal curve parameters.
It is recommended to use the specific road section as the road name. For example, a separated road section can use the left and right sections as the line name, and tunnels and large bridges can be used as a separate line.
Good route names are easy to distinguish and easy to switch quickly. It is recommended that the road name should not be too long to avoid taking up too much top column space. If it is too long, it is recommended to reduce the length and cannot contain characters.
Only text and numbers can be entered.
The station prefix is defaults to K.
