In addition, from 2000 to 2010, the private vehicle fleet grew by more than 58% in Chile (INE, 2011,2005, 2003). This was paralleled by a rise in the percentage of total trips made in private transport versus public transport (CEPAL, 2012). In common with most of Chile’s larger cities,31 these trends are leading to greater road congestion and elevated pollution levels. In 2006 on average, approximately 54% of the daily motorised trips in the Santiago metropolitan region were made on public transport (bus, metro, collective taxis).32 If daily commuting is disaggregated by income, results show that the lower-income segments are still highly dependent on public transport (CEPAL, 2012).
