In Japanese road network, there is a large difference between high and low speed class, and the intermediate hierarchy filling this gap is not sufficient. In contrast, most of multilane roads in urban area have not been achieved a certain level of travel speed, although this kind of roads are typically expected to perform the traffic function. Therefore, in this study, traffic operation using slow-vehicle lane as one solution to improve travel speed within the existing road space is proposed and evaluation analysis with the case study for "Loop Road No.7 (Kan-nana Dori)" by traffic simulation is conducted from the point of traffic smoothness. As a result, due to the proposed traffic operation, it is shown that travel speed of main traffic is drastically improved and the whole travel time of all directions is decreased. Moreover, operating modification according to the necessity of accessibility is also shown to be applicable.
