In 2002 the Mexico City government planned a BRT (Bus Rapid Transit) corridor running across the centre of
Mexico's Capital. (Hereafter the BRT unit for the two case studies will be referred to as either 'BRT' or 'MetrobusBRT').
The first corridor of Metrobus-BRT was launched in 2005 along one of the main avenues of the city with 20
km long. It is believed the Metrobus-BRT has improved mobility by 50%, reduced accidents by 30% and
encouraged a modal shift from private vehicles to public transport [23]. Based on its success, a second corridor was
opened in 2008, followed by the third Line 3 which started operating in 2011 [23]. Further extensions are already
planned and in construction [23]. According to the official figures by the BRT system operator, there has been a
total of 415 accidents from 2005 to 2012. According to these figures, there has been 51.8 accidents per year. The
most critical year in terms of the frequency of occurrence has been in 2011, with a total of 81 accidents. [24]. In the
following subsections two of those accidents that occurred in 2011 and 2013 are described briefly.
