abstract="While most motorways in Queensland are divided with at least two lanes in each direction, a few motorways have been constructed as two lane, two way roads. These &quot;half motorways&quot; have been designed and constructed with the intent of eventual duplication to divided carriageways. This study showed that a maximum 7 second time gap between opposing vehicles influenced drivers' positioning of their vehicles. The lateral positions of cars, utility vehicles, and semi-trailers are statistically different when opposed than when unopposed; whereas, the lateral positions of B-doubles were not. This indicates that B-double drivers did not tend to move laterally when opposed by oncoming traffic. On average, passenger car drivers did not position their vehicles appreciably differently when opposed by semi-trailers and B-doubles than other passenger cars, and there was no appreciable difference in passenger car drivers' positions when faced by oncoming semi-trailers than B- doubles. The vehicle envelopes are useful to understand the impacts of heavy vehicles on driver behaviour, and can also inform road design and pavement asset management.<p /><p>Language: en</p>",
