Vehicle Envelopes Design Method

Generate various types of movements in the drawing and allows the existing movements to be edited and removed. The main purpose of this tool is to demonstrate the movements governed by the vehicles specified in the design guideline that was used to generate the roundabout.

Note:

• To generate a movement animation, use the Run Animation tool.

For examples of how the Evaluate Movements tool works, please play the Evaluate Movements and Evaluate Movements on Fastest Path tutorials (for information on how to play a tutorial, see Tutorials -> Play).

Evaluate Movements Dialog Box

Error Notification

Indicates an error in generating the movement. If a movement cannot be generated, its name will be preceded by the graphic in the list. To find out what caused the error, move your mouse over the corresponding graphic and read the tooltip that will display.

Draw

Turns a movement on/off. By default, a movement added to the roundabout is drawn in the drawing.

Type

Indicates the type of path that TORUS used for generating the movement.

Symbol	Movement Type
D	Movement based on the design vehicle path
F	Movement based on the fastest path

Movement Name

Displays the name of the movement.

Entry Leg

Displays the name of the entry approach leg for the movement.

Exit Leg

Displays the name of the exit approach leg for the movement

Design Vehicle

Displays the design vehicle used for the movement.

Outer Truck Apron, Custom Truck Apron, Extended Central Island

These buttons are only available for design vehicle path movements. Fastest path movements cannot be specified to affect design features. The design features are drawn as offsets from the movement's tire track envelopes. See each type for specifics about which offset values are used.

If a design feature has not been turned on yet, clicking a feature button will turn that feature on and update the roundabout based on the movements that are specified for that feature. These design features can be turned off and on in Generate / Edit Roundabout's Central Island section.

Outer Truck Apron

Click the Outer Truck Apron button to specify that the design movement affects the design of the outer truck aprons. The outer truck apron is drawn as an offset from the movement's tire track envelopes. The External Entry Offset value is used on the entry side of the legs and roundabout while the External Exit Offset value is used on the exit side of the legs and roundabout. These values can be found in Design Guidelines' Leg Offsets Category and in Add / Edit Leg's Configure Entry Path Radii and Offsets and Configure Exit Path Radius and Offsets dialog boxes.

Custom Truck Apron

Click the Custom Truck Apron button to specify that the design movement affects the design of the custom truck apron. The movement's tire tracks are offset by the Internal Circulatory Offset value to draw the custom truck apron. This value can be found in Design Guidelines' Circulatory Offsets Category and in Generate / Edit Roundabout's Configure Circulatory Offsets dialog boxes.

Extended Central Island

Click the Extended Central Island button to specify that the design movement affects the design of the extended central island. Two design movements must be specified to enable the feature. Click this button for the first movement in the direction of traffic that you want to affect the extended central island. The movements' tire tracks are offset by the Internal Circulatory Offset value to draw the extended central island. This value can be found in Design Guidelines' Circulatory Offsets Category and in Generate / Edit Roundabout's Configure Circulatory Offsets dialog boxes.

Next Movement

The Extended Central Island design feature requires a pair of movements to define each instance of an extended central island. Select the next movement in the direction of traffic that affects the extended central island in this cell.
