Ramp Segment

You can set ramp segment parameters in the Ramp Segment form whenever you add a ramp or edit the properties of a ramp, or open it from the Road Properties form.

Width

Specify the Width of the ramp segment.

In order to end up with an accessible road, when you set the width, you may need to take into account the Berm width (if Berm access is enabled as part of your design parameters).

Gradient (%)

Specify a Gradient (%) value for the ramp segment, measured in percentage.

Berm access options

Specify how the berms will be accessed from the roads. In situations where you do not need to access every berm, you can choose to restrict access to the CREST or the TOE, or select the NONE option to disable berm access completely.

Berm access width

Where a berm is accessed by a road you can choose to make the access width the FULL width of the berm, or HALF the width of the berm. You may want to restrict berm access to people, rather than vehicles, for example.

Taper length

This input is enabled when NONE is selected as the Berm access option. An algorithm is applied to automatically calculate the length of the taper. However, if you want the berms to be tapered at a specific length, enter a value. The length of taper is the distance from the road crossing to the place where the taper starts.

You will receive a warning if the specified taper distance is not appropriate for the pre-defined design parameters. Specifying an inappropriate taper distance may lead to incorrect ramp projections.
