The Heavy Vehicle Assessment Tools assist road managers and transport operators in making informed decisions relating to heavy vehicle safety.
These tools have been developed to assist road managers and transport operators in better understanding the performance of heavy vehicles and their impacts. Each tool allows the user to calculate the performance characteristics of a proposed heavy vehicle, including gradeability, pavement impacts, risks at intersections, rollover risk and trailer clearances.
Find the maximum grade before a tandem or tri-drive vehicle combination loses traction according to the vehicle drive axle group load and friction factor.
Determine design traffic and pavement wear for different heavy vehicle combinations in terms of the number of Equivalent Standard Axles (ESA).
The heavy vehicle intersection and acceleration risk calculator enables a comparison of the acceleration performance of a proposed vehicle with an existing vehicle.
The heavy vehicle static rollover threshold calculator.
The heavy vehicle Trailer Clearance Calculator enables ensuring that the vehicle combination complies with the regulatory requirements for trailer clearance.
