Abstract:

Recently a comprehensive traffic safety study for the two main corridors was conducted in Eastern Province of Saudi Arabia. The main aim of the study was to analyze the causes of various traffic safety related issues in the Eastern Province. This was done with regards to traffic crashes with fatalities in-particular; some of the methods employed included collecting data on traffic volumes, highway speeds, travel times, traffic crashes, and conducting the road safety audit. These methods helped develop several countermeasures which targeted to reduce crashes and the severity levels associated with them, and hence improve the overall traffic safety situation in the area. This paper explains a sketch planning approach for the application of Highway Safety Manual (HSM)based crash prediction methods using road safety audit data, to help estimate reduction in crashes due to proposed improvements. The selection of the two corridors was to best represent the transportation network in the Eastern Province which consists of several different types of facilities including urban, suburban, and rural roads. Comprehensive road safety audit was performed on two corridors and the data collected thereof was archived into reporting templates. After thorough evaluation of the data collected in the safety audit process, improvements to root causes of traffic safety concerns were recommended; the HSM based crash prediction methods were applied to see the effectiveness of the improvements suggested. Reports were prepared for each of the data collection items. While the results show reduction in traffic crashes based on improvements to the corridors, this approach could contribute in its true essence when applied in combination with several other traffic safety improvement strategies.
