The efficiency of the fare-free public transport for the air pollution reduction

Abstract

The article presents the problem of air pollution in polish cities on the example of Cracow. The focus was on one of the corrective actions taken by the city – free-fare public transport during high air pollution. Changes in the city's approach to this service since 2015 and consequences for the city budget were presented. Then, the efficiency of free-fare public transport in attracting new passengers was considered. The example of the Nysa town was cited, which introduced such permission for car drivers, but withdrew it three years later. In the next step, the concentration of air pollution before and after the activation of free-fare public transport in the heating season 2018/2019 was analyzed. Particulate matter PM10, nitrogen oxide and carbon monoxide were taken into account. There was no constant relationship between the changes in the level of these pollutants in the air and the full-paid (or fare-free) public transport. There is also no reason for the need to change parameters based on witch the fare-free public transport is activated. Finally, the necessity of further efforts of central and local authorities to improve air quality as well as further research on sources of air pollution and efficiency of undertaken actions was emphasized.
