You can change the frequency of assemblies applied in corridors within intersection objects.
The frequency that assemblies are applied to corridors in an intersection is specified at intersection creation, and is controlled at the command settings level.
You can specify different frequencies for tangent, circular arcs, or spirals segments separately. Once the intersection is created, you can edit the corridor properties to change frequencies as needed. For example, suppose originally the curb return fillet is from station 1+00 to 3+00.
Then suppose that you change the frequency of assembly insertion for one or more of the corridor regions; for example, quadrant 2. Also perhaps you may add manual stations, for example, at station 2+05 and at 2+15 in the curb return fillet section of the corridor in quadrant 2.
Now suppose that you edit the intersection geometry so that the curb return fillet radius at quadrant 2 is increased. Suppose that due to this change, the curb return fillet station changed from 0+50 to 3+50 because of the increased length of arc. In this case, the intersection object will do the following:
If the corridor is set to rebuild automatically, then the corridor will be updated with the changes noted above, including manual stations (which would remain at their previous station values).
If one of the manual stations is no longer part of the new curb return fillet area, then that manual station is removed from the list.
If the corridor is set with Rebuild Automatic turned off, then the intersection will still change the corridor regions to the new stations. However, the corridor is not rebuilt unless “Rebuild” is selected on the corridor object, either in the drawing, or in Prospector.
