ARNDT

Overview

ARNDT is a software program whose purpose is to:

  • Enable road designers to identify potentially hazardous geometry of proposed or existing roundabouts.
  • Predict accident rates and costs for proposed or existing roundabouts. This enables a designer to determine if the additional construction costs of a particular roundabout layout warrant the saving in accident costs.
  • Determine whether the accident rate at an existing roundabout is similar to that expected, given the geometry, traffic volumes and speed environment; or whether there are other major factors influencing accident rates.

The user of the program is required to input geometric, speed environment and traffic flow data for the required roundabout. Utilising this data, the program displays a plan view of the roundabout for the user to determine that all input parameters are correct. The user may then choose to generate an output report that details the safety performance of the roundabout.

The ARNDT software program is based on the results of a combined research project undertaken by the Queensland Department of Transport and Main Roads and the Queensland University of Technology.
