Temporal Accident Trends of Bus Rapid Transit Line 1 in Mexico City

The chapter presents the results of historical accident data on BRT L1 that have occurred in Mexico City from 2015-2020. Some of the key findings were the following: 1) A total of 1,769 accidents have occurred in the period of analysis (2015-2020); the most critical years in terms of the frequency of accident occurrence have been 2016 (27%) and 2019 (21.2%), and as expected, the least critical year was 2020 (7.1%). 2) The most critical seasons of the year have been the following: spring (27.1%) and summer (26.5%); the less critical seasons were winter (23.2%) and autumn (23.1%). 3) The results also highlighted that accident occurrence decreases sharply at the weekends (15.8%). The main conclusion of the analysis is that 64% of accidents occurred during peak hours causing traffic congestion and negative effects on health and to the environment. More research is needed to incorporate data from 2014 to 2020 for the case of the other six existing BRT lines. Further, some relevant statistical significance tests on the data are needed.
