THE EFFECTS OF LONG VEHICLES IN THE TRAFFIC STREAM - REGRESSION ANALYSIS

Overtaking data collected for ARRB project 197 was used to determine changes in the overtaking behaviour of the population of drivers due to changes in the length and speed of the overtaken vehicle. Some eleven parameters were considered along with three overtaking types. A regression analysis technique was used and is described in this report. It was found that increasing the length of the overtaken vehicle from 5 to 16 M resulted in an increase in overtaking times of about 18 per cent. Further, overtaking times are increased by about 14 per cent for each 10 km/h increase in the speed of the overtaken vehicle. If trucks travel 16 to 20 km/h slower than cars, then the same time will elapse whilst the 85th percentile drivers overtake both vehicle types. /TRRL/
