The greenhouse gas emission generated by idling vehicles is a critical issue in the greenhouse gas reduction from the transportation sector. Recently, the mandatory application of the Idle Stop and Go (ISG) for buses, trucks and taxis is in the process of legislation. Focusing on the regulation is about to apply to passenger cars, this study analyzed the quantitative economic effects of the ISG installation by passenger car types in Seoul metropolitan area to support proper policy making. The benefit cost ratio of ISG installation on commercial passenger car of Seoul is the most effective, calculated as 8.55. Accordingly, the amount of 660 liters (per year per vehicle) of fuel and 1,606 kg (per year per vehicle) of $CO_2$ could be reduced. The results of this study might be used as an index for judgment of policy such as determining appropriate subsidy for ISG installation on passenger cars.

Since 2007, the defect confirmation test for vehicles using PEMS has been enforced in USA. This test can measure emissions from on-street vehicles using a device mounted on a car. Europe has confirmed its plan for introducing this test from EURO6, 2013. Thus, the Korean government is also under pressure to adopt this method that reflects the real-world driving conditions using PEMS, considering the emission controls for domestic heavy-duty vehicles. To provide various utilizations of the PEM, this emission test has been developed in accordance with the type of driving road, DPF, ISG, and air conditioner. This research aims to provide the fundamental materials for implementing defect confirmation tests for commercial vehicles, which are appropriate for domestic emission control situations, after studying the defect confirmation test methods for heavy-duty vehicles using PEMS.
