Accident analysis of a transport system: The case of the bus rapid transit system in Mexico City

In recent years, Mexico City has been seriously affected by the lack of efficient transport services. This is due to the excessive population growth in the City, and the lack of an efficient urban transport system has been evident. A 'Bus Rapid Transit' (BRT) system, appeared as an alternative to the problem of transport in the City. However, the system is vulnerable to accidents; it is believed that since its implementation there have been a total of 415 related accidents. When accidents occur and in particular during the rush hours, it usually brings chaos in the City. For example, a collision between a motor car and a BRT unit occurred in June 29, 2013, at the intersection of X and Y avenues. As a result of the accident, there were fifteen injured, and disruption of the vehicular traffic and took several hours to bring the traffic to normal. The paper presents some preliminary results of the analysis of the accident. The approach has been the application of accident analysis techniques such as 'Barrier analysis' and 'Events & causal factors chart'. The paper gives an account of the ongoing research project.
