Comparison of pollutant emissions per passenger for public and individual transport

Current European Union policy aims to reduce the negative impact of the transport sector on emissions of pollutants generated by internal combustion engines into the atmosphere. One of the key trends of this expansion is to increase the share of public transport. This paper develops a passenger journey scenario in an urban agglomeration, using a car and a bus. The input data consisted of tests carried out under real operating conditions, using apparatus from the PEMS (Portable Emissions Measurement Systems) group. Both tested objects met the same emission standard - Euro 4/IV. The obtained pollutant emission values were converted into passenger emissions. The results show that travelling by bus has a many times lower environmental impact.
