摘要: Using a portable emissions measurement system, 16 gasoline passenger cars were tested on fixed route consisting of different types roads in Macao and the data normalized with vehicle-specific power bin method. The HC, CO NO X emission levels seven car samples model year older than 2000 3.19 ± 5.04, 14.59 ± 22.88, 2.57 ± 2.12 g/km, respectively. other newer 0.02 ± 0.02, 0.23 ± 0.29 0.10 ± 0.13 g/km, scrappage old should be high priority to control total motor vehicles. Based relative levels, clear similar pattern for gaseous pollutants fuel consumption driving conditions was identified. are best fitted average speed inverse functions. Fuel is function. Compared conditions, factors during rush hours Macau Peninsula will increased by 61, 55, 45 90 %, This situation deteriorate 2015 if no further transportation management strategies implemented Macao. To save energy mitigate air pollutant urban area, improved traffic planning travel demand also necessary.
