Abstract

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