FOUR-YEAR-OLD NAMSAN TUNNEL CONGESTION PRICING SCHEME IN SEOUL : SUCCESS OR FAILURE?

This paper evaluates the effectiveness of a congestion pricing system imposed on two tunnels in downtown Seoul four years after it was first implemented. The effectiveness was measured on the basis on the traffic speed and volume and the number of single-occupancy vehicles using the network after the plan went into effect. It shows a dramatic rise in the number of carpool vehicles occupied by 3 or more persons, which could travel on the network without paying tolls. Toll-paying vehicles dropped from 68.5% to 29%, indicating a high degree of mode shift. After dropping initially, the volume through the corridors rose 74%, but speed increased, too. Likewise volume and travel speeds increased on the roads outside the congestion pricing corridors. Some of those gains are explained by drivers' shifting times of travel and routes as well as improved signalization in the corridor.
