Generally urban freeway plays a key role in the urban transportation system of the city. However, urban freeways are having a congestion problem on the entrance and exit ramp junctions in Korea. During the rush hours, particularly, serious traffic congestion occurs in the merge and diverge influence areas of the urban freeway in Korea. Thus, the purpose of this study was to identify the traffic characteristics in the merge influence areas of the urban freeway, compare and analyze the correlations between the lane-based traffic characteristics in the merge influence areas, and finally develop the lane-based speed correlation models at the upstream, downstream and ramp spots within the merge influence area of the urban freeway.
