Section 7 - Traffic Accidents Traffic Accidents This section provides some general statistics on the road traffic injury accidents and resulting casualties in Hong Kong for the past ten years. The traffic injury accident data are collected and coded by the Police, and stored in the database in the Transport Information System, which is developed and enhanced by the Road Safety and Standards Division (RSSD) of the Transport Department. The RSSD uses these data to identify locations of accident black spots and accident trends for in-depth investigations and devising preventive and remedial measures. The data also serves as an important source of information for formulation of road safety strategies, publicity/education programmes and on-going review of road safety legislations.
