RT Journal Article SR Electronic A1 Gnap, Jozef A1 Dydkowski, Grzegorz A1 Urbanek, Anna T1 The Effectiveness of Public Intervention in the Regional and Urban Mobility Based on the Examples of Poland and Slovakia JF Communications - Scientific Letters of the University of Zilina YR 2024 VO 26 IS 4 SP A75 OP A88 DO 10.26552/com.C.2024.052 UL https://komunikacie.uniza.sk/artkey/csl-202404-0007.php AB Ensuring the sustainable development of urban and regional public transport systems is one of the major challenges faced by public authorities. This article examines changes over more than two decades in the two key synthetic measures for balancing transport: urban and regional public transport and individual motorization in two neighbouring EU countries, Poland, and Slovakia. The findings reveal the low effectiveness of transport sustainability policies, particularly in Poland, as evidenced by a decline in public transport usage and a significant increase in the number of private cars. Comparing the two countries Slovakia's policies proved more effective, showing lower increases in the number of private vehicles and only a slight decline in the volume of urban public transport.
