| Abstract | This research investigated traffic accidents along the First Stage and the Second Stage Expressways in Bangkok. The main aim is to identify hazardous locations along the Expressways by using the Rate Quality Control Method (RQCM). Prior to applying the RQCM, it is essential to determine the severity-index rate. This study developed the severityindex rate equation by using economic losses of accident victims. To verify the suitability of this severity-index rate equation, the 3-year expressways accident data (1988-1990) were used and compared with results obtained from the previous findings. It was known that this newly developed severity-index rate provided the similar finding as of the previous study. Results of the investigations revealed that there are 8 hazardous locations on the First Stage Expressway and 7 hazardous locations on the Second Stage Expressway. Considering on-and-off ramps, it was known 3 locations (At Narong-exit ramp, Dao Khanong-Suksawatexit ramp, and Sathu Pradit(2)-exit ramp), were found to be hazardous locations on the First Stage Expressway. While on the Second Stage Expressway there was only 1 hazardous location (Paho;yothin-entrance ramp). Regarding to the types of vehicles involved in traffic accidents along the expressways, results of accident exposure analyses indicated that the more than 4-wheel vehicle type was more dangerous than 4-wheel vehicle type in terms of driving conditions. As for the periods of time, driving conditions during night time periods were more dangerous than driving conditions during day time periods. |
