    Abstract
  • The on road vehicular emission factors were determined by monitoring the vehicle's pollutant concentrations in three highway tunnels in China, and by measuring the pollutant emission characteristics of typical in use motors on the chassis dynamometer.Based on the measured data, the pollutant emission factors of the classified type vehicles were solved using the linear optimization technology.The calculating formula of the linear source strength of CO, NOx and hydrocarbons (HC) as well as the parameter values in the formula were given.Finally, the reliability analysis of the vehicular emission rates, which was based on monitored pollutant concentrations, meteorological conditions and traffic fleet compositions on an existing express highway, shows that it has a good relationship between calculated and observed results.
