As the Seoul Metropolitan Government (8MG) is trying to encourage the use of electric vehicles as the Green Car Smart City declaration, it is necessary to develop an electric vehicle (EV) delivery plan considering Seoul`s transportation characteristics. This study aims to identify strategies and issues associated with the introduction of various types of EVs based on transportation data In addition, this study proposes organizational frameworks for fulfilling the plan and estimates benefits such as emissions reduction and energy saving and costs for the plan implementation. Although the SMG set up a plan for delivering mire than 20,000 private EVs among the total 40,000 EVs, the encouragement of the private EV use was found to be significantly difficult because of high EV prices and short of charging infrastructure. Meanx4tile, taxies and buses were found to be less difficult and more economical because of their long travel distances5 fixed route operations (for buses) and easier installment of charging stations in depot. For EV taxies, pilot projects may be implemented cooperating with large taxi companies with mare than 100 fleet, The location of rapid charging stations may be determined depending on the amount of taxi traffic volumes. In the case of IN buses, buses operated on rather short routes5 for example less than 20km can be the target. In addition, some portions of niitorcycles and rental cars may be converted to EVs. For private EVs, 3,500 EVs may be on the road by mid 2013, ``which include 2,200 new cam annually, 720 company fleet vehicles, 150 rental cars and 390 car sharing fleet. Concerning rapid charging thciities, 80 charging posts located at 40 different places may be provided in order to ease the EV drivers`` anxiety. Candidate locations would be district offices, near the ramps of inner circular expressway, roadways crossing the city boundary and Hangang bridges. Besides these, 20 more fast charging posts may be installed in 10 depols of company taxies. For public standard chargers, several public facilities such as public parking lots, civic centers and libraries would be candidate locations. In the private sector, large buildings with a floor area of more than 30,000m2 would be the target for the installment of chargers. The pace of the charging facility provision should be coupled with the nunfrr of EV purchases. The proposed ratio of the nunters of EVs to public chargers are 5:1 until mid 2013, and alter then the ratio may be adjusted to 8:1. These plans would be implemented by public-private partnership where the SMG may provide administrative and financial supports. As an active measure; the SMG may take the role to lead the plans, directly managing and controlling the EVs by selling up an WV center. The analysis on expected benefits and costs for the dep1oynnt of 40,000 EVs indicated that Seoul may see greater benefits of emissions reduction and fuel savings than the cost incurred by EV purchase subsidy and infrastructure construction. In more detail, the analyses suggested that B/C ratio for the four vehicle types (private car, bus, taxi, and motorcycle) would range between 0.90 and 1.01 depending on electricity prices if the benefits last five years. If it lasts seven years, B/C ratio would range between 1.26 and 1.41. Considering that the B/C ratio of private WV sector resulted in only 0.49 0.77, the public sector EVs such as taxies and buses would generate great benefits. Meanwhile, the low B/C ratio for the private EVs implies that government should lead the promotion of EV uses in the private sector for vitalizing related industries and spreading environment friendly transportation modes.
