In a multi lanes-two ways divided road, lane changing behaviour is more important than overtaking behaviour. In this paper the lane changing behaviour on a six lanes-two ways divided urban freeway will be discussed. A 24 hours observation was carried out in urban freeway segment adjacent an arterial road. A video camera was installed in a nearby pedestrian crossing bridge to record 24 hours traffic movement of the freeway. Desk observation was then carried out by playing back the video. For each type of vehicle, the number of several movements were recorded every 15 minutes. These include lane changing to the left, lane changing to the right, overtaking from the left and overtaking from the right. The percentages of each type of movement relative to the number of vehicle for each vehicle type for every 15 minutes period were calculated. The correlations between these percentages and V/C were calculated.
