Introduction

This command provides user access to all intersections for both cross road and tee type intersections. The Intersection Manager allows users to manage curb returns across all intersections as well as add and edit individual curb returns at each intersection.

The Intersection Manager is available from multiple commands: Auto Curb Returns, Auto Roads and Project Assist.

When run, this command lists every intersection, defined by road alignment crossings and road intersects.

When the command is run indepenently (not from inside another command) users can freely navigate in the drawing with this form open.

The Intersection Manager provides three elevations of edits:

Edit all intersections for all Roads

Edit all curb returns at an intersection including the road priority (main/side road)

Edit individual curb returns at an intersection

The Intersection Manager lets users choose whether to include curb returns at each intersection, whether to include/omit batters, whether to do all-crowned or primary intersections, curb return radius and other controls.

This command supersedes the Nominate Side Road command.

Crossing Road Alignments vs Road Intersection Type

When alignments cross over each other and they are created as Roads, the softare defaults the intersection type as a Crossing Road Type. Crossing Roads generate four curb returns covering each approach to the intersection.

However, it may be desirable to set the Intersection type as a Tee type intersection. This is useful for presentation output where it is required to show the long section extending beyond the centreline of the main road.

In a Tee type intersection, the Side Road is assumed to start or stop at the intersection and form a 'Tee'. The Intersection Manager allows any any intersection to be set as a Tee type intersection.

For a crossing alignment intersection being created as a Road intersection, the Intersection Manager supports three options that trim the Side Road:

Maintain Cross Road
(none) Remove side road approach to intersection
(remove end returns) Remove side road departure from intersection
(remove start returns)

This control may be applied on a per intersection basis.

Note: Intersection Manager will not accept an intersection being converted to a Tee if the start of the alignment has a distance of less than 2 times the curb return radius from the main road centreline intersection.

Side Road Definition at crossing Roads

The 'Start' of a Side Road is defined by the side road departing from (moving away from) the intersection. In a Tee intersection scenario, this would be the Start of the side road

The 'End' of a side Road is defined by the side road approaching (morving toward) the intersection. In a Tee intersection scenario, this would be the End fo the side road.

Intersection Naming Convention

The naming convention is [ⱶ]/[+] <Main Road> - Ch:<Main Road Station> | <Side Road>
Tee intersections are listed with prefix [ⱶ] and cross roads are listed with prefix [+]

Details

Upon selecting the command the following form is displayed:

Menu Controls
These command controls apply to all intersections

Options > Create/Update Intersections
Creates all curb returns at all intersections, using the settings applied at each curb return.

Options > Remove Main Road Edges
Click to set all intersections as 'all-crowned' intersections. When selected, all curb returns will be set to remove the main (primary) road edges through the intersection.

Options > Keep Main Road Edges
Click to set all intersections a 'primary road' intersections. When selected, all curb returns will be set to include the main (primary) road edges through the intersection.

Options > Delete All Returns
Deletes all curb returns at all intersections.

Options > Reset All Intersections
Deletes and recreates all intersections using the defaults as per the Active Drawing Settings.

Crossing Intersections > Apply Automatic 'T'
Users can set a distance of alignment 'overhang' to autoamtically set these as Tee type intersections. After setting a value and clicking OK, all cross road alignments where the alignment extents past the intersection by a distance less than the value specified will be converted to Tee type intersections.
The Side Road will always be truncated to form the Tee.

Maximum distance
Type in a distance to convert cross road intersections into Tee intersections (if the alignment overhang is shorter than the value specified)

OK

Apply the Tee intesection controls

Cancel
Exit without applying

Options > Toggle OFF 'T' Converted intersections
Resets all crossing road strings to be treated as Cross Road intersections

Batters/Daylights > Set Omit all Batters
Sets all intersections to not include a batter for each curb return.
Note: this does not delete batters for curb returns already created. It sets the default status to omit batters for curb returns not yet created

Batters/Daylights > Set Include Batters
Sets all intersections to include a batter for each curb return (default behaviour).
Note: this does not add batters for curb returns already created. It sets the default status to include (add) batters for curb returns not yet created

Create/Update All Intersections
Click to create (or update) all intersections and all curb returns using the user settings in the Intersection Manager form.

Intersection Panel
Lists all intersections in the project

[List of Intersections]
Intersections are listed here. Click on an intersection to edit.

Create/Update All Intersections
Creates all intersections and curb returns as per the Crossing Intersection settings for each intersection.

Intersection button
Click to pick an intersection from the drawing to edit

Return button Click to pick a curb return from the drawing to edit

Crossing Intersection Panel
Create, edit and manage individual cross sections from this panel

Main Road:
Lists the main road for the intersection. For Tee intersections, this cannot be altered.

Side Road:
Lists the side road for the intersection. For Tee intersections, this cannot be altered.

Switch Main/Side Road
Click to switch the main and side roads in the intersection. For Tee intersections, this cannot be altered.

    'T' Intersection Panel
For crossing roads, users can set the intersection to be converted to a Tee type intersection

      Type
Set the Type of intersection to form at the crossing:
- None: maintain a full cross road intersection
- Remove Start Returns. Removes the 'Start' curb returns to form a tee
- Remove End Returns. Removes the 'End' curb returns to form a tee

      Apply Type
Click to apply the change in intersection Type
For Tee intersections, this cannot be altered.

    Intersection Controls
Sets the curb returns and intersection controls for the selected intersection

      Create > Create/Update Curb Returns
Creates all curb returns for the selected intersection as per the curb return settings for that intersection

      Edit > Override Default Radius
Click to set a single radius to apply to all curb returns for the intersection

      Edit > Override Connection Controls
Click to set the Connection Code to apply to all curb returns for the intersection. This sets the Code that the curb returns match to vertically and horizontally

       Edit > Override Templates Click to set the Template to apply to all curb returns for the intersection.

       Edit > Set Returns to Remove Main Road Edge Click to set all curb returns for the intersection as All-Crowned (main road edge removed).

       Edit > Set Returns to Keep Main Road Edge Click to set all curb returns for the intersction as Primary Crowned (main road ege maintained through the intersction)

       Edit > Toggle ON Create Returns Click to set all curb returns to be created in the intersection.

       Edit > Toggle OFF Create Returns Click to see no curb returns to be created in the intersection.

       Delete > Delete Return Deletes the currently selected Curb Return.

       Delete > Delete All Returns Deletes all curb returns created for this intersection.
