HIGHLIGHTS

  • Road safety problems of Jamuna Bridge and its approach roads are investigated.
  • Traffic operational and behavioural characteristics are analyzed.
  • Hazardous Road Locations (HRL) are identified.
  • Measures for improving the likelihood of accidents are suggested.
  • Application of surrogate safety measures as an alternative analysis approach is proposed.

ABSTRACT

According to recent statistics, more than 150 accidents and 440 casualties are happening per year on the 39 km road section of Jamuna Bridge and its approach roads, a major highway section in Bangladesh. Such statistics demand special attention for analysis, investigation, and treatment. This study presents the results of a comprehensive study on the safety problems of that highway section. The study used a special dataset recorded by the road operator for accident analysis and characteristics evaluation. Different aspects of traffic operational and behavioural characteristics are also discussed using onsite observational survey and video analysis. The analysis shows that the accidents are highly clustered at a few sites with the significant involvement of heavy vehicles, particularly trucks and buses. A total of 15 such locations are identified and considered to be hazardous. It is expected that the outcome of this research will be helpful not only to improve the safety aspects of the study section; but also to understand the way of accidents happening at the high standard roadway facilities. The application of the new analyses approaches will be useful in identifying cost-effective safety measures relating to the aspects of the road environment and driver behaviour, thereby reducing the likelihood of accidents.
