LANE BEHAVIOUR ON TWO-LANE RURAL ROADS WITH TWO-WAY TRAFFIC (PILOT STUDY)

SPURVERHALTEN AUF ZWEISPURIGEN LANDSTRASSEN MIT GEGENVERKEHR (POLIT-STUDY)

With the help of photographic recording equipment an investigation was made on a 7.5 M wide road into the manner in which vehicles distribute themselves over the road section and what causes this distribution. It was shown that the fundamental influences are: (A) The speed of travel; cars travelling at over 100 kph travel on average some 10 cm further to the left than slower cars. Similarly lorries being driven at over 75 kph choose, on average, to use a lane some 6 cm towards the left of that used by slower vehicles. (B) Vehicles travelling in platoons drive some 10 to 15 cm further left than free flowing vehicles. (C) Opposing traffic: private cars driving in two way traffic drive on average 19 cm further to the right than without opposing traffic. From these results it follows that the configuration of a cross section for two-lane roads should allow for a so-called two-way increment. The figure of 25 cm which has been used up to the present time is considered sufficient. /TRRL/
