This paper describes part of a study of the effect of overtaking provision on operating speed and capacity of single carriageway roads. The objective was to update and extend previous studies and to allow the influence of alignment and sight distance to be re-assessed. More than 1,100 overtaking maneuvers were recorded using a series of three video cameras to cover a 1 km length of overtaking section. The relationship between variables has been examined and appropriate distributions have been fitted. Formulae have been developed in which each variable may be estimated, for different types of overtaking maneuver, based on the speed of the overtaken vehicle and the accepted gap size. The results of the study are compared with previous research both in the U.K. and overseas.
