The paper presents some preliminary results of an analysis of the two BRT (Bus Rapid Transit) accidents. The case-1, relates to an accident where a BRT drives straight to a pedestrian crossing, and the case-2 involves an accident where a BRT collides with a Van. The approach has been the application of two accident analysis techniques; i.e., ‘Barrier analysis’ and the ‘Events and causal factors”. Some of the findings related to the case-1 are: a) the BRT driver's performance was “Less than adequate”; b) the ‘fence’ was not designed to withstand the impact of a BRT such as the one involved in the accident; c) the design layout of the station, the corridor, the pedestrian crossing, etc., was “Less than adequate”. Some findings for the case-2: a) the driver of the ‘V’-vehicle was in a hurry and was not familiar with the City and the BRT routes; b) the driver of the ‘V’-vehicle ignored a red light; c) the emergency response were adequate and timely in assisting the injured. More research is being undertaken to complete the analysis in the light of the new evidence that has been gathered

The book chapter presents a statistical analysis of historical data of bus rapid transit (BRT) lines A&B accidents that have occurred in Mexico City from 2005 to 2015. Some of the key conclusions are the following: (a) 484 accidents have occurred when considering both lines A and B. The most critical years have been 2008, 2011 and 2012; the least critical year, on the other hand, has been 2010; (b) overall, the frequency of accident occurrence has been decreasing in both lines; (c) the most critical seasons of the year have been the following: autumn (27.7% in line A) and winter (32% in line B); (d) the frequency of accidents increases when approaching the end of the week (Thursday and Friday) and the frequency of accidents decreases sharply at weekends; (e) 48.28 and 54.47% of accidents have occurred at the three peak (i.e. morning, afternoon, evening/night) in lines A and B, respectively; (f) 64.8% (22/73) of pedestrians have been killed when collided with the BRT buses; and (g) the most critical section of the BRT lane has been identified with 38 (11.87%) accidents and for the case of line A. Future work includes statistical significance tests on the data.
