What Makes AutoTURN Unique

Take the complicated calculations out of the equation

AutoTURN does the heavy lifting for you. Eliminate the challenges of calculating curves and modeling vehicles with different steering capabilities. Using a vehicle of your choice, AutoTURN will display the space requirements and show you the results, so you can focus on the important safety and operational components of your design.

Boost productivity and explore the best design options

With AutoTURN Pro

Save time and make better decisions. Quickly create simulations and check multiple maneuvers for different vehicles on your project. Smart tools and automated processes help increase productivity and reduce human errors. Great for discovering the best design option or modeling more complex scenarios such as traffic calming and site circulation analysis.

Tackle complex urban design and complete streets projects

With AutoTURN Pro

Adopt the principles of urban design and help make your neighborhood safer by giving all road users the space they need to move. With AutoTURN Pro, you can simulate the movement and turning requirements of a variety of cycle types including typical bicycles, bike with trailers, scooters and more to validate your design.

Test your design with a vast array of vehicles

AutoTURN Pro includes over 1300 vehicles in its manufacturer-specific and standard design vehicle libraries, so you can run a robust swept path analysis. Quickly search by library name and apply filters to define results. You can also set custom vehicle groups that match your country or local area design.

Visualize the impact in 3D

With AutoTURN Pro

Prevent costly damages to vehicles and infrastructure by using the 3D Clearance Analysis tool. This patented technology simulates the 3D vehicle envelope and analyzes multiple design layers to detect potential conflicts with lateral, ground and overhead structures.

Review your results with quality diagnostic tools

With AutoTURN Pro

The automated tools ensure your design aligns with the guidelines and safety requirements of local transportation agencies. Conduct informed reviews of simulations with the Inspect Simulation tool which allows you to check any manually produced simulations to ensure key parameters, such as steering angle, speed, and proximity to vehicles or objects, meet design criteria.

Features

Licensing Options

Transoft offers a range of licensing options to help small, sole proprietorships right on up to the largest multinational organizations meet their transportation design and analysis needs.

User Subscription License (USL) is a model where a set number of Subscribed Users are assigned dedicated access to the software through their unique logins for the duration of the license term. The software can be installed and used by a Subscribed User on multiple workstations.

Each Subscribed User represents one individual and their login and password, which cannot be shared with other users. Software activation is an easy process and can be done over the Internet.

Why Choose the USL Option

User Subscription License offers a cost-effective way for small businesses to start with one user and grow by adding additional users. For larger organizations, it will offer more flexibility in user administration and management via the My Transoft Portal. Furthermore, it can easily handle scalability and budgeting as per the business needs defined by the number of users.

Key Benefits of USL License

Have more questions about USL? See the FAQ here.

Team Subscription License (TSL) is a license option that is intended to support casual or occasional users of the software. The size of a TSL is represented as a number of allocatable seats.

Why Choose the TSL Option

While User Subscription Licenses are better for dedicated users, Team Subscription Licenses can be a good complement to these if your organization has occasional, less heavy users of the software.

How it Works

Each user of a TSL must have an account in the My Transoft Portal to request a license. Internet access is required for this process.

When an end user starts the software product on their workstation, the software will connect to the My Transoft Portal and will determine if any of the seats are available. If a seat is available, it will be allocated and dedicated to that end user who will have unrestricted access to it for 24 hours. At the end of the 24-hour period the seat allocation will automatically expire, and another user will be able to claim it.

Once all the TSL seats are allocated at a given time, no other end user will be able to use that license until the 24-hour period expires and one of the seats is automatically deallocated.

Key Benefits of TSL

  1. More flexibility for your team members
    Allows access to software for casual users without having to spend on dedicated licenses for all users.
  2. Less administrative effort by IT
    Easy access to software for casual users without IT having to allocate or transfer licenses amongst team members, self-administered by users with automatic 24-hour lock.
  3. Combined Team & User Subscription option
    Flexibility of mixing plans according to the needs of different user types.
  4. Automatic updates, new features, and content
    Bug fixes, compatibility, new version releases, or vehicle guidelines are automatically available to you.
  5. Easily manage your changing business needs
    With enhanced scalability and user management.
  6. Install the software and log in from anywhere
    Access your workstation, laptop, or personal desktop with Single Sign-on.
  7. Unlimited technical support
    Receive premium assistance for all your deployments and technical support needs.
  8. Invitations to learning-focused webinars
    Attend learning-focused webinars from our product experts and learn how our software can help streamline design processes.
  9. Simple user administration
    User Management can be performed in the My Transoft Portal, via invitation links or by Identity Provider Single Sign-on with User Provisioning.
