MultiUseWidthAndSlopeLinks

Last updated: 2021-09-08

The MultiUseWidthAndSlopeLinks constructs links to develop default top setup surfaces of lane and paved areas along with the ability to add simple daylight slopes. This multi-link subassembly also replaces two subsurface subassemblies; the EBS subassembly and the SubsurfExc subassembly. The EBS function can define a new surface parallel to an existing surface which can define the excavation below subgrade areas. The SubsurfExc function inserts subsurface excavation links per user Input parameters.

This subassembly is a non-symmetrical multi-functional subassembly where each side can be used differently and multiple function capabilities can be mixed to accomplish a variety of tasks beyond the three described here. This is because each parameter on each side can be set and targeted separately. The MultiUseWidthAndSlopeLinks subassembly does not have parameters for base and subbase layers.

Used for Setup Surface Creation 2:31

Used for Subsurface Excavation Limits Surface Creation 8:16

Used to Create an Excavation Below the Subsurface Surface 5:18

Typical attachment point is on the crown point of the roadway in both divided and undivided roadway situations.

There are three main uses for this subassembly along with multiple combinations of options.

  1. Replacing Setup-ETW assembly: Use this subassembly to replace the Setup-ETW assembly which is used to develop a setup corridor and top surface for use in various design applications such as in intersection design. Set the inside and outside width and slope parameters on each side. The slopes can also be assigned a parameter from the superelevation table. User can also set a target surface for each side along with a daylight width or slope if desired.

  2. Replacing SubsurfExc or EBS:

    The Vertical distance from insertion sets a constant vertical height from the attachment point as a negative or positive value. This parameter is overridden when either the Right parallel surface depth, the Left parallel surface depth parameter, or both is used in association with assigning surface targets. This creates a surface parallel to the target surface on either side of the assembly at the depth defined. The width of the new surface is defined by setting any combination of the Left inside width, Left outside width, Right inside width, and Right outside width Input parameters. From the outer edges of the new surface, a link may be projected on the left side to the Target Surface Left Side using the Left daylight width parameter, or if this is set to 0.0, then the Left daylight slope parameter takes precedent. On the right side, a link is projected to the Target Surface Right Side using the Right daylight width parameter, or if this is set to 0.0, the Right daylight slope parameter takes precedent. The Target Surface Right Side and Target Surface Left Side may be the same target surface or two separate surfaces.

All of the width and slope parameters can be assigned profile targets.

The Allow right width target to daylight parameter set to Yes will allow either of the right links to terminate and build a daylight point if they intercept the Right daylight surfaceprovided the Right daylight surface is assigned a surface and the Right parallel surface depth is not assigned a surface.

 

The Allow left width target to daylight parameter set to Yes will allow either of the right links to terminate and build a daylight point if they intercept the Left daylight surfaceprovided the Left daylight surface is assigned a surface and the Left parallel surface depth is not assigned a surface. The right and the left can be set independently.

 

The attachment point is usually at the baseline of the assembly as this subassembly has build t in right and left simultaneous functions, but can be attached anywhere. The right or left width parameters can be set to zero if only required on one side.

In layout mode, the subassembly shows 2 links on each side, and will also reflect any vertical offset from the attachment point entered by the user.

Info: All dimensions are in feet unless otherwise noted.  Curb & gutter dimensions are in inches.  All slopes are in a percent slope designated with a "%" sign.

Right inside SE

For the right inside link, specifies whether the superelevation slope defined for the baseline alignment should be used, if it exists. Entry of User defined, or if there is no baseline outside/inside lane superelevation values at this location, results in the user-entered slope; Entry of Use Outside Lane SE results in the pavement slope being equal to insertion side Outside Lane Superelevation Slope for the defined baseline alignment; Entry of Use Inside Lane SE results in the pavement slope being equal to insertion side Inside Lane Superelevation Slope for the defined baseline alignment; Use the Opposite Side Outside Lane SE X -1.0, which results in a pavement slope being equal to outside lane Superelevation Slope defined for the side opposite the insertion side multiplied by -1.0; and Use the Opposite Side Inside Lane SE X -1.0, which results in a pavement slope being equal to inside lane Superelevation Slope defined for the side opposite the insertion side multiplied by -1.0. This same logic applies when any of the shoulder SE values are set. Use same side lane slope results in the slope of the link to match the slope of the outside link on the same side.
