This paper analyses the link between human capital and regional economic growth in the European Union. Using different indicate the importance of effective and efficient mobility in large cities is becoming essential for planners and citizens due to its
impact in terms of social, economic and geographic development. The aim of this research is to determine factors explaining urban transport systems by estimating aggregate supply and demand equations for 45 large European cities. Supply and Demand equations are separately and jointly determined using OLS and
SUR estimation models. On one hand, the findings suggest the importance of economic variables on the supply of public transport. On the other, highlight the role of those factors influencing the generalized cost of transport as main drivers of
demand for public transit. Additionally, regional variables are introduced to capture institutional heterogeneity in this service, and find that regional patterns are powerful explanatory determinants of urban transportation systems in Europe.
