Road trains may transport goods more efficiently than conventional articulated vehicles. However, delays and frustration of the motoring public may be increased if road trains are used on high traffic volume roads. This report discusses a technique of estimating the average time the 85th percentile driver would be required to follow a road train before being able to overtake. The author related the minimum gap required by a driver to the 85th percentile overtaking time. The minimum required gap was used to estimate the following time. The author reviews the effect of driver familiarity with road trains on their overtaking behaviour and concludes that drivers familiar with road trains would not overtake in a more conservative manner than those drivers who are not familiar with these vehicles. The report concludes that road trains 20 M long are an acceptable alternative to 16 M long articulated vehicles on most rural roads and that roads with low traffic volumes are suitable for the operation of 35 and 50 M long road trains. Figures in this report indicate the limiting traffic volumes (Author/TRRL).
