The swept path analysis software trusted most by design professionals

AutoTURN® is used to confidently analyze road and site design projects including intersections, roundabouts, bus terminals, loading bays, parking lots or any on/off-street assignments involving vehicle access checks, clearances, vehicle tracking and swept path maneuvers.

AutoTURN has been developed by transportation professionals for transportation professionals and is backed by rigorous engineering diligence and regular field tests. As the vehicle swept path analysis software of choice for transportation engineers, planners, drafters, and architects, AutoTURN is used everyday. In fact, many national and local Road Administrations use AutoTURN, making it the defacto standard software of its kind for government agencies.

AutoTURN Features

Check vehicle clearances for 2D grade conflicts between a vehicle's body and terrain or even between a vehicle’s roofline and overhanging obstacles.
Innovative SmartPath tools allow the generation of continuous vehicle paths with four interactive drive modes (Arc Path, Corner Path, Oversteer Corner, Steer A Path) that incorporate speed, superelevation, lateral friction, and turn radius algorithms for realistic results.
Perform vehicle conflict analysis and receive real-time visual feedback on any simulation path obstructions. AutoTURN also comes with the ability to regenerate an existing simulation to account for conflicts that occur after path obstacles have been added, removed, or modified.
AutoTURN includes national standard vehicle libraries for: EMEA (Europe, Middle-East, Africa), North America, Canada, Mexico, Australia, New Zealand, plus many more countries. For the UK market the FTA 216 (UK), FTA CUSTOM (UK) and ARCHITECTS HANDBOOK (UK) vehicle libraries are most commonly used.
