THE EFFECT OF HEIGHT AND CONFIGURATION OF THE OVERTAKEN VEHICLE AND THE USE OF A 'LONG LOAD' SIGN ON OVERTAKING BEHAVIOUR

In an earlier report in this series (air 197-7), (IRRD no. 238026), the effect of length and speed of the overtaken vehicle on overtaking behaviour was discussed. The subject of this report is the effect of increasing the height of the overtaken vehicle, the use of a sign advising of a long load, and vehicle configuration on overtaking times and distances. An articulated vehicle and a double trailer combination (articulated vehicle hauling one articulated trailer) were used to test the effect of changing the vehicle configuration. Tests as to whether the means and standard deviations of overtaking behaviour parameters change as a result of the overtaken vehicle being higher (4 M instead of 2.5 M), displaying a 'long load' sign on the rear, or being of a different configuration were discussed. This analysis indicates that the changes in the overtaking behaviour of the driving population cannot be attributed to changes in the physical characteristics of the overtaken vehicle. A recent Swedish study of overtaking has found results which are similar to those from this study. (A). (TRRL)
