Impacts of Public Transport Conversion to Gas

Dopady plynofikace MHD

The article evaluates the impacts of the use of natural gas in public transport using a process based on modelling of emissions and the impacts of the contribution of transport to concentrations of harmful pollutants in the air. The progressive conversion of the public transport fleet to gas since 2010 is evaluated on an example of the town of Přerov (Czech Republic). Four scenarios were modelled, three of them are based on the public transport company’s real vehicle fleet composition. The fourth scenario, in which 100% of buses are powered by natural gas, is theoretical. The monitored pollutants include particulate matter and nitrogen oxides. This detailed approach to the evaluation offers a more conclusive assessment of the impacts than the method, frequently used in reference literature, of comparing air pollution levels before and after the conversation to gas, as measured at monitoring stations distributed throughout cities. The results are therefore free of other factors such as the change in the composition of the total traffic flow, stationary sources of pollution, climate fluctuations, etc.
