This category allows you to view and edit the approach leg offsets and radii path radius 1 & 2, and entry path start.

Design Guidelines' High Speed Entry Category 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.

Note: For the purposes of describing the software, it is assumed that Right-Hand Traffic is selected under Traffic Direction in Design Guidelines' General Category. If Left-Hand Traffic is selected, the descriptions with references to a right/left turn path should be interpreted in the opposite direction.

High Speed Entry Path Start

Specify the entry path start value. This is measured from the inscribed circle diameter to the start of entry path radius 1 in the high speed entry.

High Speed Entry Path Radius 1

Specify the high speed entry path radius 1 value. This is the first radius of the path which the design vehicle travels from the entry approach leg to the circulating path.

High Speed Entry Path Radius 2

Specify the high speed entry path radius 2 value. This is the second radius of the path which the design vehicle travels from the entry approach leg to the circulating path.
