AutoTurn Features

Turning Analysis

Simulate Standard & Multi-Part Vehicles Maneuvers

Ensure your design works – manually ‘drive’ forward or reverse for a standard or manufactured vehicle of your choice including multi-part vehicles (e.g., trucks and trailers) as well as vehicles with high steering lock angles (e.g., forklifts), while controlling the speed, super elevation, lateral friction, and turn radius. Create realistic reverse maneuvers using the push from prime mover method or the classic pull method.

Edit Simulation Paths

Assess the turning space and swept path, required for vehicles to maneuver safely and efficiently, and easily make small adjustments by dragging the nodes to control different parameters of the path no matter if they are passenger vehicles, buses, articulated trucks, and wheel loaders.

Check Sight Distance

Ensure drivers have enough time to notice and react to potential conflicts on the road, with sightline checks, stopping sight distance, interval distances, and object height analysis. Our 2D analysis can help identify blind spots that may be compromised by obstructed sightlines at intersections, terrain obstructions, and others alike.

Analyze Vertical Profile

View a vehicle’s clearance in a vertical profile for a simple driveway or ramp. Detect conflict or clearance issues between the vehicle body and terrain, or the vehicle roofline and overhead obstacles.

Reverse engineer the maximum uphill and downhill slopes and grade-break limits based on the ground clearances of selected design vehicles

Check Speed Profiles

Analyze the vehicle’s speed based on its centerline trajectory or path. The analysis considers the acceleration, deceleration, and lateral friction along a simulated path.

Libraries

With over 1.700 standard vehicles, quickly search by library name and apply filters to refine results or set custom vehicle groups that match your country or local area design guidelines. Libraries are updated regularly to comply with guidelines for different countries, including Canada, United States, Australia, Germany, France, United Kingdom, the Netherlands, Argentina, Brazil and Austria.

Create Custom Vehicles

Can’t find the vehicle you need? – Easily create custom vehicles by modifying a copy of an existing vehicle or by specifying each component and its characteristic individually, add user-defined dimensions for filleted vehicle radii and chamfered corners.

Oversized & Overload Transport

In 2D designs, evaluate the turning space and swept path of vehicles hauling oversize or overweight loads to check for lateral clearance from elements like structures, light poles, and utilities.

Steering Linkages

Define steering linkage between steering axle groups and vary wheels per axle to match specifications.

Accurately model electronically steered systems such as trailers carrying wind tower and wind blade sections, and vehicles transporting transformers, or use the manual steering mode, to control the steering of rear steerable axles to replicate remotely controlled steering systems.

Generate Turning Report

Produce detailed reports so that you can learn more about your simulation and identify key points so peers or stakeholders can conduct reviews. Configure the display of your simulations to match your client’s requirements or define the standards of the display by setting separate elements on specified layers.

Produce Speed Profiles

Create a speed profile report that assesses vehicle speeds, considering acceleration, deceleration, and lateral friction along a simulated path.

Generate a Turning Template

Generate a turning template displaying the key angles of the design vehicle used for the analysis to document your work.

Record and Play Animation

Record vehicle maneuvers and simulation videos to share with stakeholders. Control simulation playback and watch from different perspectives using the preset cameras.

IntelliPath®

Let AutoTURN do the heavy lifting – automatically solve possible drive paths trajectories based on the available space and the desired speed.

Simulate Bicycle Movements

Use over 12 different cycle types from design guidelines worldwide (e.g. bikes with trailers, recumbent cycles, scooters) to simulate movements and ensure on-street and off-street design projects safely accommodate the turning space required.

Check Sight Distance

Ensure drivers have enough time to notice and react to potential conflicts on the road, with sightline checks, stopping sight distance, interval distances, and object height analysis.

Reverse engineer the maximum uphill and downhill slopes and grade-break limits based on the ground clearances of selected design vehicles

Analyze Clearances & Envelopes In 3D

Highlight potential conflicts between vehicles and terrain or overhead obstructions. Instantly see a 3D swept path envelope, which models the vehicle’s underside and roofline, while considering the yaw, pitch and roll limits as the vehicle interacts with the terrain. Detect conflicts that might not be apparent with assessing clearance on a vertical profile.

Simulate Forward and Reverse Maneuvers

Perform forward and reverse vehicle movements, including front-, rear-, and front-and-rear-steering, to ensure vehicles have sufficient space to circulate around an area safely and efficiently.

Evaluate the tightest turns at low speeds to determine if the vehicle can maneuver smoothly.

Most common simulations performed are:

  • Backing up RVs and service trailers
  • Docking trucks and setting up loading zones
  • Navigating or barricaded event sites
  • Planning parking and staging areas for events, concerts, or film sets
  • Verifying clear paths in temporary layouts or behind-the-scene zones

Vehicle Clearance Envelope and Display Option

Display and analyze the various vehicle envelopes generated by different components of the vehicle to ensure your design allows sufficient space for vehicle circulation and maneuver in the design area. Export your analysis to be inserted into your design for the approval process.
