A) The BRSA claims that none of the measures tatroduced by the Government at the Malgrove Intersection have been sufficient to meet the internationally accepted road safety standard. The Global Road Safety Facility indicates that on district roads, no more than 30%% of vehicular accidents should be of a serious mature. Note that "serious" vehicular accidents are considered to be those which involve fatalities or severe injuries. The BRSA calls for traffic lights to be placed at the intersection instead of the current measures and starts a petition to lobby the government. You have been contracted by the Global Road Safer Facility to investigate the BRSA's claim. You have written to the Royal Barbados Police Service asking for data on the number of vehicular accidents reported at the intersection in Malgrove, St. Philip between the time periods 2014-2016, 2017-2019 and 2020-2022, in line with the various measures implemented. You have received the following sample data for only one year out of each time period requested and have been told that no more information can be released at this time.
