Override the circulatory offsets specified in the current Design Guidelines' Circulating Lanes Category.

Configure Circulating Lanes Dialog Box

In the dialog box, move the mouse pointer over the controls to view the associated tooltip and then reference the controls described below.

For a description of the elements drawn in the turbo roundabout in this category, see Turbo Roundabout Illustration Legend.

Circulatory Offsets for Effective Lane Widths:

External Circulatory Offset

Specify the external circulatory offset value. This is the distance from the circulatory design vehicle's outer tire track to the outer construction line/circulatory lane separator.

Circulatory Lane Separator Width

Specify the circulatory lane separator width value.

Internal Circulatory Offset

Specify the internal circulatory offset value. This is the distance from the circulatory design vehicle's inner tire track to the inner radius/circulatory lane separator.

Fixed Lane Widths

Specify the fixed lane width value for each lane.
