This study explores sustainable transport accessibility from suburban areas to the city center in Riga, using a variety of travel planning tools and mobility platforms, including Google Maps, ride-hailing apps, bicycle route maps, and micromobility rental apps. By analyzing travel time, cost, and distance across multiple transport modes—public buses, trains, ride-hailing, micromobility, and bicycles—this research provides a comparative assessment against single-occupant car travel. Data is collected from selected suburban locations to a central city point, identifying disparities in accessibility and attractiveness of sustainable travel options. The aim is to uncover which suburbs have effective, sustainable transport solutions and which are more reliant on car travel due to gaps in public transport or other sustainable mobility infrastructure. By highlighting these disparities, this paper offers insights into where sustainable transport is more feasible and cost-effective and discusses potential improvements to make sustainable commuting more attractive, ultimately contributing to reducing car dependency and promoting a more sustainable urban mobility strategy in Riga.
