The rural traffic simulation model TRARR was used to evaluate a range of options for improving traffic performance on two-lane rural roads in Australia. The options include auxiliary lanes, widening to four lanes, and reconstruction on an improved alignment. Simulated travel times, bunching rates, and overtaking rates are presented for these options for a range of terrains and traffic volumes. Benefit-cost analysis was used to derive a volume warrant for each option, based on construction costs and reductions in travel times and accidents. Minimum volume warrants of 385 to 6,800 vehicles per day were found, depending on the terrain, the existing road standard, and the type of road improvement considered. Practical warrants are likely to be higher than these minimum values, but the relative rankings appear to be robust.
