Lane changing (LC) manoeuvre has been regarded as an essential characteristic of driving behaviour, which mostly influences traffic efficiency and safety. Thus, a wrongful performance of LC could lead to accident occurrence in the form of rear-end, sideswipe, or angled crash. Consequently, to develop countermeasures to minimize events associated with LC, an understanding of drivers’ behaviours during LC manoeuvres and its duration are essential. This study explores into characteristics of drivers’ LC duration time along Kuala Lumpur – Seremban expressway. Data were collected along a selected segment using an instrumented vehicle. A passenger car was instrumented with a Video Velocity Box (VBox), which used video recording of field traffic event Hence, VBox attached to the test vehicle was used for recording LC manoeuvres in the field after which the video records were played back in a computer to estimate the LC duration times. A total of 174 LC manoeuvre incidences were observed in this study, the LC duration times of the observed motorists’ LC events ranged from 0.90 to 10.52 seconds with mean and standard deviation values of 3.02 and 1.32 seconds, respectively. Out of 174 sampled drivers, an approximate of 162 representing 93% performed LC manoeuvre in less than 5.0 seconds with most of them executed in less than 3.0 seconds. This implies that more than 90% of the drivers observed are characterized by an aggressive LC driving behaviour. It was also found that the LC duration times data obtained in this study fits a Lognormal distribution reasonably.
