It is known that traffic volume, which is representative of live bridge, has a significant effect on service level (LOS: level of service) and structural displacement of bridge. In particular, if the traffic volume is distributed in the traffic congestion time zone on the toll road, it is possible to manage efficiently in terms of customer satisfaction and maintenance management operation such as improvement of service level and structural integrity. To do this, it is necessary to induce the distribution of traffic in the congestion time zone, and it is necessary to apply the differential pricing system such as the congestion charge and the difference of toll by time. In this study, we analyzed traffic aggregation by time zone for the subdivision and advancement of the Gwangan bridge uniform fare system.
