The World's Most Used Vehicle Maneuvering Simulation Software

AutoTURN® is a maneuver simulation and analysis software that helps you test vehicle movements in your road and site design projects. In the design and planning of intersections, modern roundabouts, parking lots, loading areas or bus terminals, you can test with AutoTURN® that the designed layout can safely accommodate the expected vehicle maneuvers and turning radii.

AutoTURN® Solutions


Leading vehicle maneuver analysis and turning movement simulation CAD software. Available in Pro, Standard and Lite versions.


The leading online solution for performing vehicle maneuver analysis and simulations with PC or Mac work tools.


It provides easy-to-use tools for architects performing vehicle maneuver analysis, developed specifically for Autodesk® Revit® users.


You can perform 3D vehicle maneuver analysis and simulation in accordance with the characteristics of your rail system vehicles.


You can add special vehicles for projects in sectors such as construction, emergency and freight transportation.


You can add national standard design vehicles such as AASHTO, TAC etc. for your project requirements.

AutoTURN® Features

With four interactive driving modes including speed, roll, lateral friction and turning radius algorithms, you can quickly and easily simulate forward and backward maneuvers of vehicles. Our continuously updated features enable you to realize complex vehicle movements with reliable engineering results.

AutoTURN® includes national standard vehicle libraries for the United Kingdom, France, Germany, Netherlands, Spain, Italy, Sweden, Denmark, Poland, Czech Republic, South Africa, UAE, Israel and many more countries. In addition to the national standard vehicle libraries, AutoTURN® Pro users with an active maintenance subscription (MAP) have access to vehicles from a growing number of vehicle manufacturer libraries.

As part of our research, we continue to add new vehicles to AutoTURN® that will allow you to create realistic vehicle simulations in 2D and 3D. Advanced vehicle modeling tools allow you to define custom freight vehicles with reverse driving, steering linkages, load shapes, tracking points and much more. With advanced features, you can check overhead, side and underbody clearance distances, vehicle collision detection, terrain obstacles and visibility angles to ensure a safe design.

AutoTURN® offers powerful reporting tools to help you gain valuable insight into your simulation. You can report the maximum speed in your simulation with the Speed Profile Report, examine the steering angles of the vehicle using the Turn Report, or perform 3D analysis on cross-sections taken from any point of your vehicle route. With the visualization tool, you can easily export your vehicle simulations in AVI format videos and present your designs to project managers and stakeholders.

  • Special vehicles can be created by our experts upon your request.
  • Compatible with Autodesk® AutoCAD®, AutoCAD Civil 3D, Bentley® MicroStation®, Bricsys® BricsCAD®, ZWSOFT® ZWCAD®.


Dynamic CAD Software for Parking Facility Design

ParkCAD is the world’s leading CAD-based software that can design, control and organize any parking lot in just a few minutes

ParkCAD Features

Using ParkCAD, you can ensure that your designs always comply with regional parking standards. Parking lot angles, dimensions and parking aisle widths are stored in the Design Guide, minimizing human error.

Save, update and retrieve different design versions of your parking lot designs. Control your different plans for print or presentation in a single drawing file. Continue to develop parking lot designs that meet your client’s requirements and compare your designs to maximize parking and green space while minimizing land use.

Let ParkCAD determine parking lot layout, angles and orientations to provide maximum parking in a defined area where you set the boundaries. Dynamically model pedestrian crossings and vehicular corridors within the parking lot to better serve users, increase capacity and analyze land use to make it more efficient.

Design and develop accessible parking spaces (including guidelines, symbols and vehicle classes) according to your parking requirements. You can view the number of available parking spaces and the proportion of accessible parking spaces in a real-time view, and get notified if the regulatory requirements are met. In addition, ParkCAD can be customized to meet your project requirements, allowing you to define new standards or define special objects such as family parking spaces or electric vehicle charging stations.

ParkCAD allows you to create, store and compare multiple designs. You can compare these variations in terms of parking capacity, traffic safety and construction costs. The Quantity Report provides an approximate cost calculation based on 2D ParkCAD objects.

  • ParkCAD includes parking standards for Austria, Czech Republic, Denmark, Estonia, Finland, France, Germany, Hungary, Italy, Latvia, Lithuania, Netherlands, Norway, Poland, Portugal, Serbia, Slovenia, Spain, Sweden, Switzerland, United Kingdom, Bahrain, Qatar, Saudi Arabia, UAE and South Africa.
  • Compatible with C® AutoCAD and AutoCAD Civil 3D, Bentley® Microstation V8i, CONNECT and Bricsys® BricsCAD.


The Most Comprehensıve Solution for Roundabout Design and Analysis

TORUS® delivers a complete set of tools for roundabout design at its core. Everything you need from automated initial geometry to analyzing the safety of the design, providing a solid foundation for the upcoming phases.

Designed for all skill levels, TORUS makes your job easier, smarter, and more efficient by simultaneously balancing guidelines, safety and operation. Generating the initial geometry from a desired design vehicle and providing immediate dimensional and analytical guidance allowing you to reach project goals and design objectives faster and safer. Don’t get frustrated by the typical iterative manual process. With TORUS’ latest version, the process is streamlined with dynamic feedback, making each iteration nearly effortless.

TORUS™ Özellikleri

To promote driver safety, designers can add a new sight line that checks the angle of visibility a driver has to see oncoming traffic in the adjacent approach leg.


Enhanced workflow on the user interface with more intuitive arrangements within dialogue boxes.

Make fewer manual approximations for the fastest path for every adjustment in geometric elements. Honoring stipulated offsets, TORUS approximates the fastest paths and calculates speeds, providing powerful editing feedback to control speeds and evaluate consistency and safety.

Using TORUS’ Path Overlap Analysis, it can help detect and analyze if the natural paths of vehicles in adjacent lanes may overlap. This feature gives you the necessary feedback to highlight this type of vehicle conflict for multilane roundabout design.

Sight line analysis is an important factor for determining safety constraints in a roundabout. With TORUS, you can generate various types of sight lines (approaches to crosswalk, yield line, and circulatory lanes). Once placed, you can control their display and edit the properties used to define them.

Safely decrease a roundabout’s entry speed in rural areas by adding vehicle speed reduction treatments. They use continued curves on approaches consisting of two reverse approach curves before the roundabout entry curve.

TORUS lets you add, view, edit, and delete AutoTURN vehicle movements from a roundabout in order to demonstrate the movements governed by the vehicles specified in the current design guideline.
