Traffic related emission modelling by traffic flow simulation

  • Vehicular emission is often the main source of air pollution. The chief pollutants react with air and secondary pollutants resulting in adverse effects to the environment. European commission has legislated laws in order to reduce the air pollution from vehicular emissions. Traffic modelling has been used for many decades and particularly in the last decade, flow of traffic based on vehicle type has been used to estimate emission of polluting gases and particles. Passenger car and Heavy duty Emission Model (PHEM) is used along with microscopic traffic flow simulation software VISSIM (In German: Verkehr In Städten – SIMulationsmodell meaning "Traffic in cities - simulation model") for estimation of major two major pollutants of greenhouse gases (carbon dioxide, nitrogen oxides) and particulate matter emitted from passenger cars and heavy-duty vehicles, based on their technical performance characteristics in a traffic flow at a typical German motorway segment. With a country’s fixed fleet composition for a particular year, PHEM gives fuel consumption and emission as outputs using fuel types used (diesel or petrol) and based on the trajectories of the vehicles. This study is planned to exploit the developments and investigate the validation of this software with HBEFA. Different 25 scenarios are created for a German motorway segment with varying traffic behaviours; and the emission results between two emission modelling software tools are compared.
