| Summary | This study is to estimate motor vehicle emission factor more rationally. The fuel efficiency of vehicles by real road traffic is larger than by catalog mode. The motor vehicle emissions and their variability characteristics by real road traffic were investigated by using on-board emissions measurement system. Using these results, more rational estimation method of motor vehicle emission factors in the future will be developed. |
