This investigation is a study of voluntary weaving movements on two-lane motorway roadways under conditions of uninterrupted flow. The movements are studied both microscopically and macroscopically. Information on movement and position characteristics of vehicles participating in weaving was obtained from a series of induction loops placed in a sequence. Four types of weaving by changing over to the left lane and two types of weaving by changing over to the right lane were distinguished. In order to determine the relationships among the variables, multiple regression analyses were carried out. A relationship was found to exist between weaving behavior and lane configuration. On the passing (left) lane, the gaps accepted are considerably shorter than those on the shoulder (right) lane thus causing the well-known phenomenon of nonuniform lane utilization under high volume conditions. Moreover, weaving movements involve a high potential of danger to multilane traffic flow. The maximum of weaving movements was estimated at a total of 600 weaving movements per hour and kilometer at a traffic volume of 2,000 veh./h. In addition, the frequency of passing was also included into the consideration and related to the frequency of weaving. It turned out that, also under low volume conditions, passing generally means overtaking more than one vehicle at a time. The relationship pattern found has been used to define weaving behavior for a model to simulate traffic flow.
