Specify the parameters to create a minimum turning circle envelope.  The vehicle will move in a specified direction and then turn at its maximum steering angle.

Option

 

Description

Envelope Type

You can generate the following minimum turning envelopes:

  • Absolute minimum envelope.

  • TRH 17 template.

  • Around a kerb (TRH formulas).

Kerb Radius

The radius of the kerb (in m) used in the Around a kerb option.

Through lane width

The lane width that is available.

Coordination Interval (m)

The interval at which the position of the vehicle will be calculated.

Simulation Type

There are three options:

  • None - Only the vehicle position will be displayed.

  • Track Path - The track path of the vehicle will be displayed.

  • Swept Path - The swept path (vehicle limits) will be displayed.

Turning Direction

The minimum turning envelope can be determined for a left or right turn.

Simulation Direction

The simulation may be in the forward direction, or in the reverse direction, for single unit vehicles.

Turn Through

Enter the angle through which the vehicle must turn to complete the manoeuvre.
