  • Road traffic microsimulations based on the individual motion of all the involved vehicles are now recognized as an important tool to describe, understand, and manage road traffic. Cellular automata (CA) are very efficient way to implement vehicle motion. CA is a methodology that uses a discrete space to represent the state of each element of a domain, and this state can be changed according to a transition rule.

  • The estimation of emissions largely depends on the quality of emission factors used for calculation. The study on the estimation of emission factors is important for calculating the emission of air pollutants from road traffic in Ho Chi Minh City (HCMC). The result of this study is the selection of a suitable method and tracer for estimating emission factors of 15 volatile organic compounds (VOCs) from C2-C6 and NOx from road traffic in HCMC. The survey has been carried out in 3/2 Street, District 10, HCMC from January to March 2007. Three VOCs compounds with high average emission...

  • The Swiss work was based on a provisional national PM10 emission inventory. It was first disaggregated to a km2 grid. Dispersion functions for primary PM10 emission were defined in an empirical dispersion model which was used to calculate the concentration of primary PM10. The contribution of secondary particles was modelled by using simple relationships between precursor and particle concentration. The long-range transported fraction was taken from European scale models. The PM10 fractions were then summed to create the PM10 map.

  • The population exposure without PM10 fraction attributable to road traffic is shown in Figure 6. Compared to total PM10, the frequency distribution changes considerably. Most people would live in areas with PM10 values less than 20 µg/m3. In France and Switzerland, less than 3% of the population would live in areas with PM10 greater than 20 µg/m3. In Austria, this portion is higher due to an increased non-traffic caused regional PM10 background.

  • The maintenance of road pavements in England has become a costly necessity, due largely to the large volume of commercial vehicles using the roads which cause pavements to deteriorate quickly, and makes their repair more difficult to carry out. These roadworks incur not only direct works costs, but also indirect costs from factors such as congestion, motor accidents and pollution. There is obviously a need for cost-effective maintenance that minimises the occurrence and duration of these disruptions.
