Spatial Patterns of CO Vehicular Pollutant in Macao Peninsula

چکیده
This paper describes a new approach to assess high-resolution Carbon Dioxide (CO) distribution for the peninsula of Macao Special Administrative Region (S.A.R.). Firstly, two widely used vehicular pollution models, namely Danish Operational Street Pollution Model (OSPM) and United States intersection vehicular pollution model (CAL3QHC), were applied to evaluate the roadside CO concentration from vehicular emission. It was found that the OSPM was more suitable in this region. Therefore, the OSPM was adopted to simulate such pollutants in front of each building block in the Macao peninsula. Geographic Information System (GIS) was utilized to run all model cases and store the model results automatically. The spatial pattern of CO distribution in all the main streets of Macao peninsula was found and the influence of traffic loading was shown by a spatial comparison of the CO concentration and traffic loading.

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 NOX 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, respectiv...
متن کاملSpatial Analysis of Urban Form and Pedestrian Exposure to Traffic Noise
In the Macao Peninsula, the high population density (49,763 inhabitants/km2) and the lack of control over the number of vehicles (460 vehicles/km) have led to an increase in urban pollution. To provide useful information to local government and urban planners, this paper investigates the spatial distribution of traffic noise in the Macao Peninsula. The interactions among urban form, traffic flo...
