THE EFFECTS OF LONG VEHICLES IN THE TRAFFIC STREAM - PRELIMINARY APPRAISAL AND ANALYSIS OF THE DATA

The analysis presented in this report, establishes a basis from which the effect of length and speed of the overtaking vehicle on overtaking behaviour will be determined. The forward visibility of an overtaking motorist was either an oncoming vehicle or a crest or curve and overtakings were classified according to the visibility restriction. The results in this report indicate that it was acceptable to pool overtaking data for the two types of visibility distance restriction. It was also shown that many parameters, used to quantify the overtaking manoeuvre could be reasonably modelled by a lognormal distribution. There were some restrictions and these were discussed. The correlation between parameters were examined; there were no unexpected high correlations. Finally, overtaking times have decreased since the early nineteen forties, and Australian motorists tend to take longer to overtake than their Scandinavian counterparts. /Author/TRRL/
