SRT threshold calculator

In 2000 TERNZ developed an algorithm for solving a set of analytical equations to determine the Static Roll Threshold (SRT) of a heavy vehicle.

A key feature of this algorithm is that a reasonably accurate estimate of SRT can be obtained using vehicle data that is easily measured.

The algorithm was implemented as a web-based software application which is freely available for public use. Two versions of the program exist on the internet:

an New Zealand version
an Australian version which was developed for Mainroads Western Australia.

Another version that provides the user with greater flexibility in specifying input parameters can purchased from TERNZ.
