The specialized software for three-dimensional road design

VI-Road  is VI-grade's specialized software for three-dimensional road design.

VI-Road supports a series of advanced capabilities, such as the possibility of modeling kerbs and of specifying variable friction coefficients and track disturbances.

The user interface provides access to specific tools for creating, manipulating and smoothing driver lines.

VI-Road enables to estimate the static limit speed profile for a given vehicle on a specified trajectory. VI-Road supports the OpenCRG standard, allowing straightforward management of the crg data file.

VI-Road is compatible with other VI-grade products, such as VI-Driver, VI-Animator, VI-CarRealTime, VI-DriveSim, VI-Motorcycle, VI-BikeRealTime.


  • Interactive generation of road surfaces for different multibody solvers
  • Road data postprocessing with specific tools (smoothing, corner cutting)
  • Creation of driver trajectories
  • Generation of road geometries for visualization into simulation postprocessing software (VI-Animator, Adams PostProcessor)
  • Different features for automatic and fast road design: Analytical mode, Oval model, Extrusion mode,Meshed model
