Nowadays, population growth, economic development, and expansion of metropolitan areas have led to the rapid growth of the world’s motor-vehicle fleet. As a result, ambient air pollution in many cities of the world has become dominated by emissions attributable to traffic, including dust, tailpipe, and non-tailpipe emissions of a variety of pollutants such as PM, CO, NOx, and benzene.

Traffic-related air pollution (TRAP) has been proved to be a main contributor to unhealthy ambient air quality, particularly in urban areas with high traffic volume. In addition, TRAP has become a major public health concern and been linked to a wide spectrum of diseases by substantial evidence. 

Therefore, it has become a consensus globally that TRAP deserves greater attention. And TRAP monitoring is particularly important for assessing air quality and exposures, thus supporting the formulation, implementation, and evaluation of related policies, and ultimately protecting public health. However, there are three main problems of TRAP monitoring in Asian developing countries. 

  • The quantities of TRAP monitoring stations are very limited.  
  • Domestic technical guidance for TRAP monitoring station set-up and operation is lacking. 
  • TRAP monitoring data is not effectively utilized to support policymaking nor used for air quality assessment


To improve TRAP monitoring in Asian developing countries, the session aims to introduce the experience and good practices of countries and cities that pioneered in TRAP monitoring and promote better TRAP monitoring in Asian developing countries. 

The session will discuss the following: 

  • Emissions of traffic sources  
  • Health effects of TRAP 
  • Low-cost sensors application 
  • Design and application of TRAP monitoring networks
