Four-year-old Namsan Tunnel congestion pricing scheme in Seoul : Success or failure?

Before the congestion fee charging, toll-charged vehicles amounted to 68.5% of the total traffic volume of the two tunnels, and then the share dropped to 29% afterwards. The empirical analysis results for the effectiveness of the congestion pricing scheme are very promising. Key Words: TDM, Congestion, Pricing, Effectiveness, Seoul

1. INTRODUCTION
Seoul has earned a notorious reputation for its severe traffic congestion. In order to mitigate the congest i o n problem, the transportation policy of Seoul Metropolitan Government (SMG) had been mainly focused on the supply of transportation systems such as constructing new urban freeways and subway lines until the early 1990’s. However, after 1993, the SMG has approached traffic problems from a different angle in response to the limitation of the past transportation policy to solve the traffic congestion problem. The ne

Abstract

The purpose of this paper is to evaluate the effectiveness of the congestion pricing scheme at Namsan #1 and #3 tunnels in downtown Seoul four years after its implementation. The effectiveness of the scheme was measured by the changes of various traffic impacts. The traffic volume of the two tunnels was reduced by up to 25% for the first month. After that time, the traffic volume started to increase again and then exceeded the previous volume level. However, average travel speed of the two tunnel corridors improved by up to 74%. The overall traffic volume of the four alternative routes was increased; nevertheless, their average travel speed increased as well. The number of carpool vehicles occupied by 3 or more persons including the driver during the peak periods was remarkably increased. (The rest omitted)
