This research is to analyze reasons for violation of the Self Carfree day policy. It also analyzes satisfaction of the policy participation incentives. The results are that the violation rate is increasing if the drivers live in a zone which is highly energy consuming, which has low potential demand per bus stop and low trip generation per number of houses, which therefore requires more bus routes and bus services, and in which the drivers pay more car operating fees and show less tendancy towards participation even with the 5-10% oil price increase. The results are significant at the 0.05 level.

This study presented a method to allocate RFID reader sites for the weekly no driving day program. In resent years, three metropolitan cities begin to operate the system to resolve the traffic jam, air pollution, and oil cost, which is expected to be operated across the country in a few years. In this regard, the accurate verification of the observance of the cars which are participated in the system is needed so that the more benefits are rewarded to observing participants but not violating ones. Thus, this study distinguished road sections where the system of the Daegu metropolitan city cannot determine the observance of the participated cars when the cars detour the RFID readers by employing a set of data from the traffic census, digital maps, and terrestrial photographs of the superstructures on the roads. Then, the appropriate sites for additional RFID readers were determined based on those sections in the road network and the types of the road superstructures.

최근 환경문제의 심각성이 고조됨에 따라 Co2 배출량 감소계획에 따른 세계 각국의 정부주도로 민간 및 지방자치단체에서도 그린에너지, 저탄소 녹색성장 프로젝트, 승용차요일제 등 다양한 정책을 시행하고 있다. 따라서 탄소저감의 효율적인 방안으로서 승용차 운행을 줄이고 자전거 활용의 활성화에 대한 관심이 증대되고 있다. 본 논문에서는 자전거활용의 활성화를 위하여 자전거 도난방지와 관리를 위한 저비용의 무선 네트워크를 활용한 임베디드 제어 모듈과 모바일 서비스 기반의 자전거 관리시스템을 설계하고 구현 기법을 제안하였다.

It is necessary to evaluate the greenhouse gases (GHGs) reduction policy by central and regional governments to set up the suitable GHG emissions measures. Quantitative, qualitative and synthetic methods have been adopted by previous researches to estimate GHG reduction policy. However, these methods mostly focused on the results of the reduction policy, rather than understanding and fixing the integrated structures of GHG emissions. In this research, System Dynamics(SD) was applied to 1 million green homes program, self-carfree-day system and carbon point program. The results showed that SD analyses could be appliable for the estimation of GHG reduction policy by developing the feedback loops and dynamic simulation model. SD can be consider as a supplementary tool to estimate the GHG reduction policies through the recognition of the structure in complex real system.
