Free fare public transport and urban mobility: Economic, environmental and social effects

Free fare public transport (FFPT) has gained popularity as a mobility policy aimed at increasing ridership, reducing car dependency, and enhancing social equity. However, its economic viability and environmental effectiveness remain contested. This paper synthesizes findings from multiple case studies to assess the real-world impacts of FFPT. The analysis reveals that while FFPT successfully increases public transport use, it seldom leads to significant reductions in car travel unless combined with complementary policies such as congestion pricing or urban redesign. Moreover, the financial burden of FFPT often outweighs its benefits, straining municipal budgets and sometimes compromising service quality. Targeted subsidies and service improvements emerge as more effective alternatives. The study concludes that FFPT alone is insufficient for sustainable urban mobility and should be implemented as part of broader, well-integrated transport and urban strategies.
