An appraisal of the urban scheme for sustainable urban transport

The purpose of this study is to appraise the impact of integrated land use and transport policies on environmental objectives for sustainable urban transport. Furthermore, while considering environmental objectives, we find the most effective policy from an existing policy case and policy scenarios for Namyangju-City, in the Seoul Metropolitan Area, as an experimental appraisal. The simulation results show that the CO₂ emissions reduction effects of the policy scenarios of integrated land use and transport is greater than those of existing policies. Specifically, the largescale development plan, such as scenario 2, which is the development scenario of the subcenter-area in Namyangju-City, is more effective than scenarios 1 and 3. While the effect of scenario 2 is evenly spread across the city, the effect of scenario 1 is noticeable in the central-area and the local district-area, and the total reduction of CO₂ emissions within scenario 2 of the subcenter-area is similar to the central-area development of scenario 1. The CO₂ emissions reduction effect of Scenario 3, which is the development of the local district-area in Namyangju-City, is relatively lower than that of any other scenarios. Also, it is effective all over Namyangju-City but ineffective for the local district-area. Comparing the CO₂ emissions per capita, while a do-nothing case is estimated to emit 1.95 tonnes of CO₂ in 2031, the results of an existing policy case and policy scenarios 1, 2, 3 are estimated to fall to 1.50 tonnes in 2031 from 1.72~1.79 tonnes in 2016.
