Expand an arm and click Exit in the left hand pane. The Exit page is displayed.
Select the Number of Lanes from the drop down list.
The Lane Width is measured between centers of lane markings. The innermost and outermost lane widths are measured to the nearside and offside definition lines respectively.
The Splitter Radius is the radius of the offside definition line at the splitter.
The Nearside Radius is the radius of the nearside definition line at the splitter.
Select Equal Spacing Between Lanes to even out the lane width.
By default, an additional lane at entry is added at the nearside and the offside approach lanes are extended to the yield line. If you wish the additional lane to be added to the offside then select Add Lane to Offside.
If this exit is not relevant to flow calculations, e.g. it might be a service road, then select Ignore in Capacity Calculations.
In all cases the Max and Min values represent the limiting values from the adopted design standard.
