Stations available for stakeout

You can customize the stations available for stakeout in an RXL, LandXML, or 12da road when staking a:

• Station on string

• Skew offset

To customize the stations available, select the stakeout method and then tap next to the Station field in the Stakeout screen. The Select station screen appears, listing the stations on the centerline. Tap Edit to modify the station interval and the types of available stations.

Station interval settings

If required, edit the Station interval for lines and Station interval for arcs and transitions or accept the default value set when the road was defined. A separate station interval value for arcs and transitions enables you to tighten the interval for curves and more accurately represent the design on the ground.

Select the station interval Method:

• The 0 based method is the default method and gives station values that are multiples of the station interval. For example, if the start station is 2.50 and the station interval is 10.00, the 0 based method produces stations at 2.50, 10.00, 20.00, 30.00 and so on.

• The Relative method gives station values relative to the start station. For example, if the start station is 2.50 and the station interval is 10.00, the Relative method produces stations at 2.50, 12.50, 22.50, 32.50, and so on.

Available stations

To configure the types of available stations, select the appropriate Available Stations check boxes.

Depending on the road type, you can select the following:

• Computed Sections defined by the station interval
• Horizontal Curve (key stations defined by the horizontal alignment)
• Vertical Curve (key stations defined by the vertical alignment)
• Template (stations where templates have been assigned)
• Super/Widen (stations where superelevation and widening has been assigned)

The station abbreviations used in the Roads software are:

PI	Point of intersection
PT	Point of tangent (Curve to tangent)
RE	Road end
RS	Road start
SC	Transition to curve
SEE	Superelevation end
SEM	Superelevation maximum
SES	Superelevation start
SS	Transition to transition
ST	Transition to tangent
STEQ	Station equation
T	Template assignment
TS	Tangent to transition
VCE	Vertical curve end
VCS	Vertical curve start
VPI	Vertical point of intersection
WE	Widening end
WM	Widening maximum
WS	Widening start
